In vac, the atmospheric pressure push the mold together. When bladder tries to open the mold, so you would need stronger mold to hold

@@LestaAZL I was wondering this same exact thing. Thanks for the logical response.

Yes, it's exactly as LestaAZL has commented. The moulds you need for a pressurised bladder need to be incredibly strong (usually billet aluminium) in order to resist the deflection of the 'unbalanced' pressurised bladder. Therefore they tend to be very expensive to produce. An internal vacuum bag setup like this exerts equal pressure on the inside and outside of the mould, allowing much lighter, more cost effective composite moulds to be used.

Good point. Vacuum + plastic film= waste + money. You can make a thicker mould just by adding 3-4 layers of fiberglass or carbon fiber, hence achieving a stronger mould. I prefer the bladder anyways

What pressure would a pipe like that hold

Thanks for the comment, that’s great to hear. 👍

Can i ask what kinda parts you made and for which team? I'm just a big F1 fan and i'd like to know

Thanks, yes, we're pleased to be getting back on with them.

@@easycompositestv great work! cheers from Italy!

Haha, thanks a lot. We'll get cracking then!

Thanks very much. Yes, we try to show a range of ways of doing things. We will, in fact, be returning to some simpler and more entry-level topics over the next few videos but they'll always be showing a process that's used for a good reason, even if that reason is simply to avoid the need for complex tools or equipment. Stay tuned.

Because you learn something just by looking and get ideas what you can do with it .

Thanks Caleb, I'm glad you found it easy to follow. That's always the challenge with these complex subjects.

Thank you Lukas, we appreciate your comments and support.

Thanks Greg, we'll do our best.

Thank you for watching and commenting Mac Mac, we’ll keep them coming 😀

Thanks very much, I'm really glad this is inspiring you.

Hi, yes, that was our experience when we started out too. That's why, - as we acquired knowledge, figured processes out, or developed our own methods - we wanted to share them with others.

Thanks a lot, I'm glad this made it clearer. Yes, we might well do something quite soon on the compression moulding with silicone. Stay tuned.

@@easycompositestv Excellent! Keep up the good work!

Thanks Leon, stay tuned!

And that's why they cost millions of dollars as well.

At least they won't rust.

If you want an idea on the labor involved, check out the youtube channel Street Bandito. One of the guys is making (and is almost finished with) a full carbon body 240z. The guys does some fantastic work and his car looks gorgeous, all done himself.

GUNER 400 parts;) But dont worrie you Pay for the extra Carbon time:)

@@readysetnogo I believe their channel is the reason why this video was recommended to me. I'm interested in handcrafted/homemade carbon fiber stuff. I'm glad there's other fans of the Street Bandito out here. They deserve more love for all of the effort they put into their builds especially the carbon z.

Our pleasure. Thanks for watching!

Thanks again David, glad you enjoyed this one too.

Hi Arsh, thanks for your comments. I'm not sure we'll make a video specifically about making carbon fibre wheels because it's unlikely that anyone at the learning stage of the their composites is going to take-on making carbon fibre wheels. However, the process would essentially be a combination of what you see in this video and in our bike frame video, with a lot of extra complexity and really critical calculations and knowledge for safety.

Hi Karl, yes indeed.

meh not really. fiberglass parts are cheap as fuck. Cf is only slightly more expensive to work with. but it looks cool and people are easily fooled. so why not charge out the ass for it? the skills here are very basic. the tools very basic.

Diesel Ramcharger Basic skills? Then 99% of the population doesn’t possess basic skills. Lol

@@SkypowerwithKarl Just because you can't do it doesn't mean the rest of the world can't.

Link: ukposts.info/have/v-deo/hINla2dpbKqG258.html The part is around the 13:10 mark

on that particular part there appears to be no undercuts on the larger opening but the throat of the intake would have likely been separate part of the negative keyed into the rest of the negative part. The process would be generally the same as creating the first mold for a standard part as seen in Easy Composites "Fibreglass/FRP Split-Mould Making Guide" or "How to Make a Prepreg Carbon Fibre Mould", except instead of having a split on the outer layer you would split the internal buck to easily remove it. For more complicated internal geometry you would have to include draft angles in the internal buck in order to ease removal as seen in "Making a Carbon Fibre Bike Frame" @32:30 with removing the inserts for the pass through on the frame.

Hi Christian, I'd agree with what Andrew says.The best process for parts that are 'smooth on the inside' would either be a made tool (if the part could be removed from the without becoming stuck) or it could be a male tool in more than one part, i.e. a split male tool, this would be common, or - for really complex shapes like induction shapes with multiple turns, then you could even use a sacrificial core. These wash-out or melt-out cores are a whole complex subject in their own right but in general they are made from a material that can be dissolved with water or melted out (lots to consider in terms of cure temp of the prepreg vs melt temp of the core) which is either cast (into a mould) or CNC machined.

It knows you better than you know yourself!

Haha, great, that's good timing then. We aim to please :)

Please you do indeed, i've started with Fiberglass and Carbon Fiber just recently, but have been watching your videos for years and they showed that it is alot of work but no magic involved, i have quite a few molds already, the whole vacuuming equipment is coming together piece by piece, until then i am using a food vacuum pump with the tubes and the clothes bags, which both release awesomely haha

he said you can but its not worth it

It's really very difficult to make something like this using a resin infusion process. Nothing is impossible but the practicalities of dealing with dry fabric and then handling the infusion consumables, it just makes it too difficult.

@@easycompositestv indeed it is. The resin needs heated and degassed for a start. The material needs an activator and heat, to create a pre-formed shape. And then the resin needs injected with compressed air pushing it in, with vacuum at the other side helping draw the heated resin to every crevice in the pre-form. That's the "vague" theory used by aerospace to make resin infused carbon parts 👍 (I worked on autoclaves in this way)

@@E9JMX The only things that I find wrong with your reply is #1. The A+B epoxy creates its own heat to cure. #2. You only need vacuum to draw the epoxy into the material. #3. Adding compressed air would add air to the mix. Keep in mind I used to do these processes when making carbon fiber prosthetics. Adding to the fact that we both understand manufacturing, our products might require different processes. Just throwing my two cents in.

Thanks a lot, we'll do our best to keep them coming.

Thank you, glad to have you on board :)

Thanks Dave

For sure, this is labour intensive work!

Koenigsegg* but yeah it's stupidly hard. And koenigsegg makes sure all the weaves line up then sand down the outer to a perfect matte finish. So if it takes two hours to make this tube for a normal person, you can look at about four to six for koenigsegg.

That's right I'm afraid!

Hyperian if you want to make them lower buy price just use industrial machines and bigger number of employees and you can produce more so price will be lower

@@PakleniVuk industrial machines = money. More employees = money. More machines + more employees + more money invested does not equal more demand.

@@samyoung8470 if it was that simple, we would be swimming in carbon fiber products nowadays.

We probably won't make a video on this exact mould but we have covered the process (pretty-much) in two of our other videos. The split-mould we used in this video is a prepreg carbon fibre tool. The patterns (for the two halves) were CNC machined from epoxy tooling board like in ukposts.info/have/v-deo/e4dyqqVve3-Lmqc.html and then the mould halves made from made from XT135 carbon 10:00 28/04/2020fibre tooling prepreg like in ukposts.info/have/v-deo/o2R4mHeshaCalps.html. There are other solutions for making high temperature moulds, such as a hand layup process using high temperature epoxy tooling gelcoat, resin and paste which you can find out about in this tutorial (on our website) www.easycomposites.co.uk/#!/composites-tutorials/High-Temp-Tooling-Gelcoat-Putty-Mould

You're welcome, glad you enjoyed it.

Thanks for watching Gonzalo!

Thank you! Appreciated.

Hi Kevin, I would say that modest sized external components are a good starting point. Interior trim pieces tend to be rather fiddly and have added complexities of mounting lugs etc. If you're thinking of using prepregs, such as shown in this video, then induction components could be a good place to start, or some exterior details like scoops or vents.
