Is there anyone better than Paul to explain anything about composites??
Thanks Jeeth, very kind!
Paul is brilliant, as is everyone we've ever dealt with at Easy Composites - literally everyone from sales, technical support, shipping, accounts. Honestly the best company we have had the pleasure of working with.
@@jonathanw2036 Thanks Jonathan, we dig the positive vibes, it makes it all worthwhile!!
This channel is awesome. Thanks for the videos! Otherwise I found "Explore Composites" does an amazing job at showing quick tests of how different composite samples are made and how they feel. Also has a website with a list. Not sure if he's private or business.
Chuck composites, Chuck carbon Fibre. Bottom line is, in this world there's no better teacher than Paul
How can people even give Paul a thumbs down! He is amazing! I wish I could give him more thumbs up for his amazing videos!
Hi Victor, thank you for your kind comment! I'm glad you enjoy our videos! We've got more coming out soon :)
When the worst part of a channel is that they don't have as many videos as you'd like... Really amazing work. It's really inspired me to try and make my own custom cycling shoes, still in the research and planning phase but you guys make all the processes seem doable, thanks for that and for all the information! Keep the amazing videos coming!
Hi, thanks for your kind comment. We've got plenty more videos in the pipeline! Good luck with your project!
Damn, he is the best person to explain everything. Great speaker!
Thanks Patek2 :)
Thank's for a great video! Very informative as usual!
Thank you guys. Just another excellent video instruction. You are a brilliant communicator and I always gain knowledge I can use from them. Keep them coming. How about a internal bladder prepreg project???? You know you want to LOL.
It may be something we consider for a future video.
Thank you. I learned all for your videos. 😁
Amazing video, top notch production and quality education!
Thank you for your kind comment! We'll have more videos out soon :)
another great video from easy composite, dear Mr. Statham I am still waiting for some new videos for RC planes, and thank you so much for all your hard works and amazing videos
Thanks Amir, we do have some tutorials planned for RC aero/fixed wing UAV. Some many ideas, so little time!
@@easycompositestv I wish you always be so busy with customers so you don't have time for making tutorials :)
thank you team! we're in the infusional paradise, enjoing
Cheers Ed!
that's a great product i wish i knew about them sooner,
Good stuff! I've found your channel to be very informative but was wondering if in the future you might do a video on the use of core materials in more complex parts. When to use them and when to not and perhaps best practices for a high quality finish. Keep up the great content!
We'll certainly try to incorporate it into future videos even if we don't make a dedicated one but I agree, more information on the best use and when/how to choose core material options would be insightful.
Great vid, excellent explanation, THANKS!!!!!!
You’re welcome, thanks for the feedback.
great explanation and presentation
Thanks Peter, glad you enjoyed it.
More videos coming!? y'all are the only company I get my products from! #onlythebest
Yes we have a schedule of videos being filmed over the next few months. Glad you like our products and videos!
Again a fantastic video. Thanks
Thank you, glad you enjoyed it.
Hi Paul here from easy composites At this stage it's an Arnold Schwarzenegger level catchphrase
Get to the choppppppp....ed carbon fibers and add 10% of the weight of the resin to it before mixing it with the hardener
very nice video, i love your products
Hi Cherif, Thanks for your kind comment!
In few words these products is fool proof resin infusion , i need them.
Great video!
Glad you enjoyed!
This makes me think this would work Vey Well for making fenders for my nova!😲😲😲👌🏻
Certainly where you are unsure and need the extra help with resin distribution and controlling the vacuum then that will work very well.
@@easycompositestv some of the fender lines/shape tells me this would be incredibly useful!!

Thank you for learning a lot from Easycomposites KZhead. I can study while watching videos even though I don't understand English. I wonder if this video is a product that helps prevent pinholes from forming if you use them.
It depends on the cause of the pinholes but the correct use of these products can help with resin distribution and flow, which if it goes wrong can be a major cause of pinholes.
Brilliant 👍
Paul is a celebrity in my mind.
Haha, well, it takes all sorts!
Great info - I have a part that is a meter in diameter and a half meter wide with 2 compound curves - I've struggled to get the resin to infuse to every corner and edge. I'll give the MTI and MVS a try to see which does the best job in my application. Thanks.
Thanks for the comment, yes, this sounds like a good candidate for these products. It might be due to the flow characteristics of your laminate, if it’s a thick stack or you have some slower flowing reinforcements in the (like plain weave carbon, biax or UD) then switching to an outside in infusion and using the VMS Strip would be a good way to go 👍.
@@easycompositestv , the product is a challenge because of its half round shape. Think inner fender shape, its halfround front to back, and curved from outside to inside. I've been struggling with it for some time 😁
Beautiful
A great clear demonstration as always. Thanks for sharing. Around 11:00 you say about leaks in the bag. If, say, there is any drop in my test before hand is that not suitable for use with these hoses? What if I have a tiny drop that I can't find. Usually I wouldn't worry about it but this sounds like once the infusion is complete the vac is doing very little?
Hi Ben, when considering a leaking bag, it would be exactly the same when using this type of product as when not using them; either way, a leaking bag means you’ll gradually lose pressure in your bag and compromise the laminate. To overcome a leaking bag in an infusion is very difficult because at the end of the infusion, the resin will be locking off the vacuum side; if you leave the pump running then you’ll draw off too much resin and, of course, as the resin starts to gel then the vac will stop doing anything at all. Using a membrane product, when the resin reaches the the membrane it will lock off the membrane in that place, the result would be much like closing the vac line and switching off the pump.
This channel is very cool, I’ll like to see if they can do a custom hook for a Mazda 3 2015 😳😳
Hi Alain, I'm glad you enjoy our channel! It's unlikely we'll make a video about a custom hook for a Mazda 3. But if you wish to carry out the project yourself, we would be happy to provide technical advice by email at Technical@easycomposites.com
Hi Thank you for your valuable information. Do you have a video on making carbon fiber drone parts? frame, propeller etc. (especially the propeller) I will be glad if you share such videos
Not at the moment but we'll certainly add it to our list of requested videos for the future. One thing to bear in mind is that propellers can be incredibly difficult to manufacture in terms of the balance and structural integrity.
Tech ingredients has a video on carbon fibre propellers 🙂 kzhead.info/channel/PLzrI14lOlSqfR9lOz-3dgf7fQaD6C9_bW.html
@Easy Composites Ltd Could we get a video on laying up carbon fiber honeycomb panel, possibly using 3 different ways, a wet layup with no oven, CF pre preg, and how to use film adhesive?
Hi Solomon, it's a video we will be doing in the future however we are currently working on some other fresh content prior to addressing this particular video
I have watched hoping you will make an episode telling me how to make make my current project. I am making a 20ft car/motorcycle body. Wet layup over a foam buck. Do you have any techniques for non-mold non-vacuum bag projects?
Hi Shea, no general suggestions but maybe some thoughts would come to mind if you have a more specific question or problem to solve. I guess we could point out that polyester resins will melt styrofoam or XPS foam but epoxy won’t. Although epoxy is a more expensive resin, you’ll save a lot more that the difference by using XPS foam for your shape and the coating that in epoxy to protect the foam. You should then apply a release agent to the epoxy shell and then do your wet layup for the component onto that, that way, you will be able to remove the component from the former shape quite easily.
@@easycompositestv for sure, thanks for the reply! I'm working on a streamliner body right now. My biggest concerns are keeping the carbon from lifting and getting a smooth finish from the final peel ply layer. I have some videos on my channel about the build and I just layer up my first layer today. I was watching your channel to get pumped up😂. Trying to break a landspeed record!
please do a video on making complex objects like propellers
It may well be something we cover in a future video
Thank you, so useful ; do you send your items to Italy? (or you got a distributor here?)
Hi Paolo, yes, we can ship to Italy. Since Brexit, the process is not quite as smooth as before but we are opening a new warehouse in Europe in the next couple of months which will make things very smooth again. Until then, we can still ship to you but you should read the ‘Brexit’ page on our website.
Thank you.
Will you ever be making a video that covers making very small, intricate parts? I've been thinking about taking a swing at this to make a carbon fibre version of my gaming mouse, I just can't figure out if it would be possible to do since it has screw holes, PCB mounts, and clips integrated into the different parts. It would be especially difficult to hand laminate I would imagine.
We have videos demonstrating various laminating processes, it may be easier to skin the mouse or make a carbon fibre shell and 3d print the internal mounting points and bond them in place.
@@easycompositestv That's a very good idea, thank you for the suggestion
You Mike good video but maybe can make about more difficult infusion . Wi make infusion for 5 cm ticnes. And longest take 24 h
Hi there can you make winglets for Kawasaki H2R
Question on vacuum technique: I have some experience with vacuum bagging as a woodworking doing veneers, laminates and fiberglass-epoxy. For large parts, I used vacuum capacitors (air tanks that already have a vacuum pulled) hooked to the bag. These capacitors great accelerated pulling the bag down. Would this work with composites being infused?
Well, yes, you can include a reservoir in the setup, this will have some vacuum ‘capacity’, but ultimately it won’t really have any positive effect in a typical infusion setup. It’s rare that the time it takes to pull the bag down is much of an issue but if it’s something you want to speed up, it’s often easier to just connect up a vacuum cleaner which can do the initial emptying of the bag in seconds.
Paul if I were to infuse a very large surface area would I be correct in thinking that a series of these infusion strips spaced, say, 500mm apart would ensure a good even distribution? Specifically, I mean for an outer layer of carbon on a boat hull.
A series of strips or one long strip could be used in that way to help ensure it works as you planned it.
Is there already a video on the trick used at 9:37? I am really curious how to fix it!
No specifically as this material and careful infusion layup design is what can be used to prevent dry patches like this.
New to infusion.. Just curious to how come you don't have inlet one side and outlet directly opposite?
Hi Tom, on a simple component you can do that and in fact, you normally would. Products like MTI are useful on more complex shapes where the advance of the resin flow might otherwise close off air paths to certain parts of the component, or where you can’t predict where the resin will get to last. Take a look at our other, more conventional tutorials on resin infusion, we have 3 other tutorials on the subject - they should give you a good grounding.
I think this was just a "how not to do it" to demonstrate the problem you could face in more complex parts
@@dejayrezme8617 which is exactly what he says in the video.
sickest one use calculation
Hi exist some kind of honeycomb prepreg or like that where we improve structural but a lot less weight. instead of aluminium or nomex aramid. Someting more 3D like cubic where give strenght in all axis i mean Up/down and left/right. honecomb only give in one axis Up/Down. I was thinking in some prepreg fabricwave in cubic.
I'm not aware of any premade structure like that on the market sorry
If i wanted to do the with the core section, but the part is also a visual part that should look perfect form the flat side, how do i go about doing that? Doing it in two stages/infusions maybe?
Two stages is a possibility, or as suggested you can sand the edges of the core to a taper so there is no line around the core edge. You can also use layers of carbon tape to fill the "step" at the edge of the core if sanding the core is not desirable.
@@easycompositestv aah, i did not catch the detail about chamfering the core edge! Thanks for making a video about this!
Thanks a lot for all this information. I want buy your product to make carbon fiber parts. I have no experience and I live in the USA. What and where would be a would starting point? I plan on using core materials to make parts about 1/2 inch thick or less. Thanks again
Hi Hoss, I guess it depends on what these components are; that wasn’t clear from your comment. Certainly watching through our back catalogue of tutorials will give you a really good grounding in practical composites, even if you don’t fully understand all you’re watching!
@@easycompositestv I want to make coolers or ice chest. Also some boxes for my tools to carry around. I work in construction and I am an automotive technician. I have the need for a better product in both fields. You can email me at: Fragoso289@gmail.com if you wish. I went in your website and sent the company an email. Asking about shipping to America and other questions. Haven't heard back from you guys yet
@@hoss2200 There are similar companies in the US. I feel it would be bad form to mention any of them here, but it would not be that difficult to find them by searching using google or duck duck go or what have you.

Make a video on Ultra Filtration Hollow Fiber Membrane Epoxy Pouring in real way method
would it be possible to strip the outer material away and T off with the MTS? would it be useful to strip smaller spots off towards the end to ensure a full vacuum pull with a designated "pull to" point or should it always be sealed off at the end?
If its not sealed off at the end, the resin will just flow easier through the open end rather than the microporous membrane.
Can you make a video for how to calculate epoxy for vacuum infision ?
Our other infusion videos cover how to calculate the amount of resin used.
However much your cloth weighs, use the same weight with resin, plus a dribble more to allow for resin in the tubes.
Interesting you didn't include the MTI Valve in this video, are you going to cover that in a future video? Have you guys had a chance to review the valves yourselves? I actually used to use the MTI Valves 4 or 5 years ago, but then stopped when I did a number of tests and couldn't actually notice them working at all, I was still able to absolutely flood the feed side of the bag with resin when theoretically the valve should have regulated and shut off flow long before that happened. I know DD-Compound say there is a small chance that a bit of debris can get into the valve and prevent it from functioning, so I was never sure this wasn't the case - but it seemed unlikely to be occurring on 100% of the tests that I did.
It is possible we may cover it in a future video as this video was more about the membrane products. We have not had any problems with them ourselves and they do seem to function as intended.
Would it be easier to use a heat sealer to seal the MVS ?
Its not something we have tried ourselves.
Next one Core materials which one is the strongest one how easy to separate layers without closing it around (when u need to cut trough core exposing it) /// or when closed after part is made (like grinding edges to V shape inside and then filling with epoxy + fibers mix etc to protect the edges) which one is easier to use how easy to damage by tightening the screws etc. or by hiting it with something overall ....strenght comparsion between new ones like u use - 3dcore , to older ones like soric etc
It entirely depends on the context and application. Strong as in stiff? Impact resistance? Shear strength? etc. It also massively depends on the skins. A core material is akin to the supporting member on an I beam. Its sole purpose is to improve efficiency of the composite skins.
what's the best alternative to your product for viewers located in Australia?
Hi Michael, I’m afraid we don’t have any dealers or distributors in Australia and we don’t specifically work with any firms so its difficult to direct you anywhere. We can ship non-Dangerous Goods (reinforcements, tools, infusion equipment, PrePreg) easily and at a reasonable cost but unfortunately Dangerous Goods like resins are more of an issue.

Can you guys make a tut over how to make carbon fiber wheels for cars? Would love to make a version of the 18 inch wheels that come with the tesla for weight savings and so that the caps still fit on the outside. (I have the rimetrix orbitals, not the factory aero caps and they are much more efficient and stylish).
Hi chase, its unlikely we’ll put a wheel video together as not only are they one of the most complex composite products you could look to make in terms of the structural integrity and balance but also, the safety critical nature of the wheel makes it something really best left to specialists who can perform the necessary pre-build FE Analysis and Structural Calculations as well as the testing of the finished piece to recognised standards. For an oversight though, there is a great Koenigsegg video on KZhead showing their processes.
@@easycompositestv thank you! So I shouldn't attempt this myself?
@@aggiechase37 Hi chase, it really would be up to you. We personally won't be making a wheel due to the reasons above.
Does the MVS strip have a peel ply or release film on the bottom side? So could I place it directly on the surface of a part (such as flax) on which I am not using peel ply and mesh?
You would need something underneath so a strip of Peel Ply just under the MVS would be fine but without it, you wouldn't be able to remove the MVS from the reinforcement.
Make one video on car metal rood replace by making carbon fiber? 🙏👍❤️
This would be the same processes as in our carbon bonnet/hood video tutorial.
@@easycompositestv but how they add air vents and sharpen design ...etc.
@@rajkargutkar3751 Normally by building them into the mould itself so making a pattern/buck with an original fitment hood with any required openings/vents before producing the hood mould.
is there a reason you don't use pleats on the vacuum bag?
For a flat panel example like this, it's not necessary and would just made it less clear to see what's going on with the membrane and resin flow, which is what we're trying to show in this video. For anything other than a flat panel then we would have pleats in the bag.
Does Easy Composites Ltd have an US distributors?
At the moment, no, I’m afraid we don’t. We can and do ship direct to the US from the UK though. Shipping is, of course, not expensive but generally our prices are lower and (I would say this!) our products are very good, which hat can compensate quite a bit.
I need help I’m trying to start a small business making forged carbon parts for my mk5 Supra can you help me find a kit right for me ?

waiting for new videos... Pleas upload some new projects!!!
Hi Soma, we have lots of videos in the pipeline. We'll be sure to upload a new video soon!
I can ask why it is no longer possible to buy your products from Italy as it is not possible to have them sent to you ..
The good news is that our EU warehouse opened officially last week and so from hereon, you will be serviced via our facility in the Netherlands rather than the UK. This means that we’ll be returning to a situation more similar to that of Pre-Brexit/Pre-January 2021 so goods that you order will no longer need to pass through customs and there would be less hassle relating to import duties, taxes, VAT, etc. Please see more details here: www.easycomposites.eu/buying-from-easy-composites-eu However, whilst they are both wholly owned by the same directors, the EU and UK sites have to operate as separate businesses for legal purposes and to prevent any issues, you will need to register a new account on the www.easycomposites.eu/ website.
Did you ever get around to sharing the trick you mentioned at 9:35?
Good question! Now I think about it, no, not yet. Will hopefully be doing another infusion video soon so will make sure it’s included 👍
Do y'all sell in the USA?
Hi , we can ship to the US, no problem in fact we have ship every day and have a great customer base in the States. Smaller orders container Dangerous Goods such as Resin and Solvents can be a little expensive but the good news is that you can get an accurate shipping cost easily on the website, simply add items to your basket and then choose ‘United States’ on the basket page. If you have any questions though, feel free to drop us an email to sales@easycomposites.co.uk
I just end up bagging a whole part and then throwing about 4 inches of MTI hose on the back side of a mold that has strips of Peel ply around the part. Usually works pretty accurately because I'm good at predicting where the resin will go. But I cannot get rid of pin holes in any part for the life of me

@@easycompositestv sad news 😭 I always have problems with applying wax (sometimes the result still stiuck in the mould). in your opinion, how many times do you need to apply wax to the new media at least?
But why you made first example that way? If in and out will be on opposite side result will be different,and I thought that's the rule.
Because of the really simple demo pieces, doing that would create a perfect infusion, and not show the example of what can go wrong, It doesn't make sense if you look at it from the viewpoint of "how to do i make a perfectly flat peice of carbon fiber," but think of it more in the terms of what could happen on more complicated parts where the in and the out arn't perfect, or the part has a lot of weird areas to it, making it borderline impossible to do it the standard way,
Grease1991 is correct that these are demo pieces so it was necessary to create a situation that is non-perfect to demonstrate the product. Ordinarily a flat sheet would be a simple infusion.
9:30, let the gravity help
Surely the vacuum line should have been at the furthest point away from the resin line, to try and eliminate dry spots in that 1st finished test piece!? Having it as close as it was, was always gonna draw resin into the vacuum line too soon, and mess up the flow rate of the resin.
Well, yes, exactly. That was the point; to demonstrate what would happen if the resin reached the vacuum line before the laminate had fully infused. I thought this was clearly explained but maybe not. Anyway, you’re quite right, you wouldn’t knowingly put the vacuum connector right night to the resin line.
This was explained VERY VERY clearly in the video.
“Unintentionally keeping as a secret” but we will keep it as a secret and tell that secret at a later date...🤔 Great video tho.
@Gary Bednarz I’m going to be sitting on pins and needles until I find out.
Haha, classic cliff-hanger! Actually, it didn’t quite fit in here but it will in one of our upcoming vids, stay tuned 😀.
"Pins and needles".. Well probley just a needle..
@Gary Bednarz I saw a guitar builder dragging a squeegee over an infusion. I always wondered about that!
I imagine just plugging in another vacuum line or repositioning it to the other corner.

@@easycompositestv Intentionally or unintentionally, you had a chance to correct it at the time of editing and you *chose* to not include the data. I’m expressly looking for large CF projects to examine so I can keep from destroying materials and tools but I can’t really do that since I now I have valuable information being kept from me. It doesn’t make sense to take a project then offer 99% of the data that is needed to complete the project and we both now now badly projects can go with less than adequate data. #SixSigma
