DO NOT MAKE CARBON FIBER PARTS AT HOME (Making Charge Pipes) [DIY] with CR-Scan Lizard

[@Futemire]

I think the fact that you let everyone know that you failed multiple times is very important for those first starting out. Too many people get discouraged after watching other videos that make it seem easy and as if they get the perfect product every time or after the first try. So thanks for being completely transparent about that.

I worked CF composites at Koenigsegg, and the strategy that ended up working was kind of close to how we worked. The difference is that we never use sleeves for anything, but instead regular 240gr weave, but pre-preg. The reason your weave ended up wavy and inconsistent is because your weave wasn't cut out for the dimensions of the pipe. My suggestion is to buy 240gr pre-preg CF weaves. You can store rolls of them pretty much indefinitely in a freezer. Take your CAD drawings of your molds, "unfold" them onto a 2D plane, and cut the shapes into your CF weave + like 1cm in each direction. Then just laminate the mold with your CF weave, and use a box cutter to just cut off the excess along the edge of the mold. The pre-preg makes your CF weave kind of stiff, so it's easy to cut through it without the weave bunching up. Apply 2 more layers but leave the overlap on one of the molds; when you connect the two molds, take the overlap and make that the connection point to the CF on the opposite mold. And then just connect the two molds the same way you did, with the vacuum tube running down the middle, the breather, and all that. With the pre-preg you also won't need to do any treatment, like polishing etc. It all comes out looking good enough to be inside an engine bay. All you gotta do is cut off those excess strands of epoxy that seeps out the cracks of the mold with a box cutter.

Hello friend. I know the job is very easy with prepreg carbon fiber. I have prepreg carbon fibers. But I wanted to make it a handlayup for less cost. Thank you so much for your advice.

with pre-preg u wont need to polish them right? are you apply the polish for your ceo's head?

[@ohedd]

@@farhangorengtepung for internal CF components we don't polish, but all exterior and interior components including the visible engine bay gets polished. But no you don't "have to" polish it; polishing just adds the extra 10%. Yes, that includes Christian's head as well.

[@loopie007]

I would recommend watching a couple videos on how CF bike frames are made. Typically they use a bladder to blow up the inside of the tube, then vacuum the outside. And, as others have said, they use precut pieces of prepreg. It's fun to do it your way sometimes, but when you want the job done, check what others in the industry are doing. Did you do any pressure testing on the pipes? What about the mounting tabs?

[@jgetscensored7837]

You should consider using dowels as alignment pins next time you make a mold. You could probably program your printer to do it for you, or just add them after the fact. But it would really help in ensuring alignment of the two sides is proper.

[@noimagination99]

True, but here, I think the vacuum bag's pressure forces alignment of the outside edges of the molds, so it works fine.

[@pawpatina]

you can see they are wavy so they lock together.

[@BestKiteboardingOfficial]

You could have wetted the carbon, wetted the inside of the mold, clamped the molds and then inflated internal bags, no need for vacuum bag on outside. Sometimes it's easier this way. Props for showing the process and failures. Nice work.

[@diegojosephia]

I like to use inner bike tubes inside of the internal bags it let me controll it a lot. Also using a weave works better for me then tube

[@C-M-E]

Glad you got it figured out, but yeah, these are typically done with build-up layers. The outside layer adjacent to the mold face is the 'pretty' layer and done as one piece cut to shape, then subsequent layers reinforced for strength flange into the other half (the overlap) while the 2nd half fits inside the first at the seam. Too many people get stuck on the epoxy thinking that it's the component that gives a part strength, when its primary job is to essentially lock the carbon in place for shape. There's a lot of tricks you can use for other considerations specific for its working environment that also could also enable its use for downpipes, but there isn't an 'off the shelf' resin specifically for that due to epoxy's low heat tolerance. I specialize in extreme heat use and it took me several years to formulate one that can withstand exceptionally high heat (currently exploring in the 5600*F and above neighborhood) but in that usage, you most certainly won't have a 'show level' esthetic part anymore. In the future, I would print your parts as you intend them to look and function, then build your molds in fiberglass with generous flanges, use your tool coat for the inside and progressively sand up to 2000 grit for a perfect surface finish. Prepreg isn't strictly necessary for one-offs, but if you were to be doing this in a production use, you will end up with a stronger part for optimum carbon/resin ratio and less overall waste. But then again, you'd also need all the support equipment for pre-preg and not be doing this on the internet.😁

[@smnkm4ehfer]

Prepreg is significantly easier to work with tho 🤔

Hey amazing video, i was wondering instead of vaccum pressuring the moulds, would it been possible if you had tightly secured the two halfs of the mould and filled air in those transparent pipes that you filled inside the carbon fiber pipes? I am not a professional at this or never tried doing this kind of stuff before but all this time i was thinking of this idea to fill air in those pipes. Would this idea have worked?

[@helldiablo8471]

I started doing carbon fiber work, and I have two words for you: wet sand. Even at 120 grit it works super well! Zero dust, and the sandpaper lasts way longer. You don't even need to wear a mask or gloves. I also found 320 grit works the best for leveling the surface, without worrying about sanding too deep.

[@TeslaDIY]

i tried making an intake pipe for a friend a while back, was super messy but somehow got it to work, it was far from perfect, but i wasn't aiming for perfection. Props to you for trying until its perfect, very inspiring as always!

[@pieterreynders5607]

Vert nice! If you can't use prepreg's to ensure a nice glossy finish (the finish of your mould determines that) you can apply a layer of 2k clearcoat and wait for it to just "flash-off" proir to moulding. You get a great finish after just a little bit if polishing.

[@Hawk013]

For a part like that, since you were using two layers anyways, I think I would have done a single layer in each half as seperate halves, then assembled them and spiral wrapped it to bind it all together with the second layer.

[@ryankingston7733]

I love that part with the windows error sound along with the p-dog screaming, so fitting especially when things don't go the way we would like. Great stuff, enjoyed watching your video. Thank you : )

[@justagraze2603]

pretty cool. i specialized in carbon fabrication for about 10 years. just wondering why you didnt vent the bladders to atmosphere or pressurize them after the molds were under vacuum? at least i didnt see that in the vid, but they turned out really nice in the end regardless. well done mate!

[@alextasarov1341]

I think it’s hard to notice, but it seems like he sandwiched the bladders in the seal so that air could enter them. He places another strip of seal on top to make the seal above, but there is nothing sealing the bladder from atmosphere. It looks flat but air can definitely get in.

[@Mortimusmoose]

Because he isnt using bladders. Look closer, those are just small tube bags. Very common for what hes doing. Thats how I make these tubes as well. No need for bladders. He needed to put breather inside the tubes though so his.....vacuum....(wont get into that) would hold the carbon to the walls of the mold. My thing though, is since he put it in an oven, why not use prepreg instead? Oh well.

[@jnxmck]

I've got no knowledge in carbon fabrication but I'd have thought pulling a vacuum in the bag then pressurising the tubes that pass through the carbon sleeves with something like a bicycle inner tube (which would obviously need to be cut and re-sealed so it's no longer a loop) so they conform to the walls of the moulds while the epoxy cures would have been a good starting point?

[@JamesBalazs]

@@Mortimusmoose yeah I was also confused by the lack of a proper vacuum pump, lack of breather on the inside, and why he originally tried to use sleeves/tubes absolutely saturated with resin, rather than just hand laying sheets in the first place when he literally made a 2 piece mould to allow that. Putting a discouraging title making out that it's impossible to DIY is really annoying when there's so many basic things wrong with the method he's using, which could be learned with a tiny bit of research...

[@Mortimusmoose]

@@jnxmck Yes....you just described a bladder. Perfectly fine for this. You can do it either way. If you dont have access to a bladder, you can do it the way he did it, or how I described. Bladders are the easiest way to do it though for sure.

[@SupercarSeany]

Appreciated the persistence here. Would there have been any way to actively inflate or pressure the inner vacuum tube to expand the sleeve a bit better? FWIW ice also seen a KZbin builder 3d print a positive mold, put the sleeve around it. After curing with resin, they melted the 3d mold out in a hot water bath.

[@franckbrunie4759]

Just some air in the inner tube and seal it would have been enough

[@TheShaddix]

Your level of persistence is inspiring to say the least! 99% of people would've given up after the first attempt had failed... But you kept going which is insane (in a good way). And I still can't believe you do all of your work directly on your laminate floor. You should build a small workbench since you do so much of this stuff as it can't be that comfortable working on the floor!

for the carbon sleeves, i think id try to use vacuum for the outside and compressed air in the inner tubes.

[@kovacs9974]

Superb video! I'm just wondering something, would it work if you use the carbon sleeves with the vaccum bag inside of them and you try to put air (more pressure than normal atmosphere pressure) in them to push the carbon sleeves to the walls of your mold ? Maybe you've tried it already though.

[@foesfly3047]

I wondered about that too.

[@ddegn]

Using internal bladders is a common technique when molding hollow parts. When the part is open on bother ends, you can use an inner vacuum bag and an outer vacuum bad and join them together to vacuum bag the whole part. Two days ago, the channel *Matthieu Libeert* made a tutorial about making carbon fiber tubes. One of the methods used a mold which included the above described technique for vacuum bagging the part.

[@tangochaser4030]

Quick question since Ive never tried to make anything out of carbon fiber. Can you make a mold of the original pipe, fill that mold with plaster, then make your tube by wrapping the carbon fiber around the plaster mold? Kinda like making a cast item.

[@mn5789]

[@charleswatts1864]

Don't you need to pressurize the inner liners? So they expand and force the shape of the inside of the tubes? Maybe just clamp the shells together and pressurize the inner liner?

[@thescalefactorypl9932]

I was also wondering that, kevlar karbon sleeves are rather cheap and if that worked it would make easy composite charge pipes. Some 80s group B cars featured kevlar charge pipes so i think it's such a pity that this is still not popular in tuner scene

[@hybridracers]

Its armchair quarterbacking but any tube made really needs to be over a mandrel and if they have any curves they always start with a silicone bladder. They look great. Your molds are top notch for being 3D printed. It was far more trouble than I would have gone through when I would have just made a split mold and put a bladder in it.

[@young3nsinglej]

A bladder was myb1st thought. Would also reduce any imperfections in the internal flow too, seen as these are going to have very fast flowing air pass through them...

[@DM-pm8hr]

Great Video, but I have a question. If I see this correct, the 2 sides of a pipe are not connected by fibres, only by matrix (resin), because you used 2 pieces for the mold, right? Are you not concerned if that withstands the pressure inside the pipe?

I would advise you to build or buy a professional dust system. You can make money now, but you would't be able to reverse the damage in your lungs later. Start on looking dust extraction system for woodworking. I personally built myself one from 1.5kW ventilation motor from a grill house.

[@JonasE-l7q]

@@keronGR Which filters are you using in that process? I Would think you would have to use something in the ballpark of HEPA H13 to get the Carbon particles out of the air right?

[@keronGR]

@@JonasE-l7q Think this process as a multiple stage. First you need to build a dust separator. Nothing fancy here, just youtube and you will find plenty DIY. This is important, as all the heavy particles or objects will fall in the bin. After the dust separator, you build a box with 2 or three filters. FIRST is a PRE-FILTER (G1-G4 class), SECOND is a BAG FILTER (M5-M6, F7-F9 class) and at the end you can add an absolute Filter or HEPA. Me, I don't use HEPA filter, because it reduces the performance of the vacuum motor. I just frequently wash and clean the filters. I use a 1.5kW ventilation motor, it's so damn strong it sucks many of my tools laying on the table. But I would also add another fan, ziptied to a prefilter, mounted on the back of the table, so that it absorbs even the tiniest particles, which the vacuum system has missed. Hope my answer is helpfull

Nice job. I have 2 questions. 1) 10:38 You left a margin of approximately 4-5 mm in the canvases on both halves of the mold. And when you pressed these halves to each other, in my opinion, these protruding edges should have bent in a chaotic shape along the entire border of the joint (in particular, considering that the canvases are crimped from the outside with a mold, then, in my opinion, they should have bent inward of the pipe). But 13:07 when you pulled them out, along this joint line only excess epoxy resin formed in the form of a white crust (it seemed so to me), but for some reason both halves of the canvas lay Perfectly on top of each other, as if there was a clean overlap. How did it happen ? Is it possible to control this ? 2) 10:57 What functions does this green ribbon perform ?

[@RexinOridle]

Dude, the amount of effort you put into them, hats off to you.

could you have used a balloon inside the carbon sleeves to hold inside the mold until cured? Then resin/vacuum

[@Kojo_Deon]

please what is the name of the hand pump, that was used to sucked the air?

[@Protocol-X]

Nice to see people showing failed attempts too. What is the brand and name of your high temp clear coat spray? I've been looking for something a few months now but no luck for one with a gloss finish.

[@ECOLAPStudio]

Hello friend. I used DUPULI Supertherm clear spray.

[@BoisesBaggedSupra]

Great video. Would it have been easier to secure the two pieces together and inflate the plastic on the inside of the CF instead of vacuum sealing it and letting the suction expand it?

[@beno0055]

no, the mold would have to be much much stronger.

Is it possible to use the lidar camera on the iPhone 14 to 3d scan that pipe instead of buying a 3d scanner?

[@GermanTopGameTV]

I have build intake runners myself and I know your pain. I have made two different sets for an isuzu and a vw pickup truck. I enden up using the method you employed as well - laying up both sides and then pressing them together with a fiber buttjoint. The idea of using a sleeve is appealing and there probably is a way to get it to produce good results. I have however, not found it yet. The obvious downside to this method is that there is a defined breaking edge as no fibers go all the way around the part. I have developed a solution to this issue, but I haven't used it yet so I can't tell you if it works.

[@mostwanted6379]

hey love the video i have a question did u throw away the failed attempted parts or did u saved to used some how? that lead me to the next question can u recycle carbon fiber parts some how ?

[@Eric-Marsh]

This is some really good stuff. You've got me watching and thinking about how I might approach my own projects.

[@ThatGuysProject]

with the failed ones, could you not of forced pressure into the internal bag to force it to expand, while the outer bag was pulling vaccum?

대단하십니다! 궁금한게 검은색 에폭시접착제는 제품명이 먼가요?ㅎ

[@Justjackson7]

Can you reuse the 3d models or would you have to make a new one all over again?

[@lynchingacers]

Another random thought was there a way to do an inner support, like an inflated bike inner tube cut and reglued to support the tubes from inside pushing into the mold

[@ludgerheitkemper6501]

Very nice tubes, but I mean, the really important is the inner tube. The metal connectors you mount made an edge in airflow. I made several tubes for bikes and test on a dymo. The smallest edge costs power! My tubes are shorter, wraped around of 2K-silicone forms. So the inner form was defined better. Sorry for german english ;-)

[@robertsaca3512]

Exactly how necessary is it to place precision instruments, such as a scale, down on the table with brutal aggression? Does every tub and cup need to be smashed together as well?

[@MRKchallenger]

At least! You back. Good 😁👍

[@liewchengyeh]

Isn't it better to use latex tube as the expansion insert ?

[@deltadia]

Amazing. I don't know why yt recommended this but I love the editing and the fact that all the failures were shared. I had no idea carbon fibres were sold in sleeves either!

진공시킨다고 틀 속에 있던 파이프가 원통처럼 펴지는 이유가 궁금합니다

[@franciscor2840]

Hi, what high temp clear coat are you using? I’d like to use it on my project.
