Rapid Prototyping Forged - Chopped Carbon Fiber PART 2
Тәжірибелік нұсқаулар және стиль
Second part of the video!
In the first video we did some trial and error to prototype and understand the material using polyurethane and chopped Carbon Fiber.

In this new video: part 2 we are using better and stronger mould made out of aluminium filled epoxy resin. www.easycomposites.eu/tool-ca...
and now we are using epoxy infusion resin instead of the polyurethane, resulting in more translucent parts and stronger parts.
Why didn't I start with epoxy? like mentioned in the first part we wanted to go through the testing results as fast as possible to determine a fiber to resin ratio. the polyurethane has a curing time of about 20min, epoxy resin would be around 6 hours. Meaning we went through all these steps quickly before getting good results directly with the epoxy resin, saving us some time and money.

Your every video is worth gold. Still, no way to create a perfect piece without practice and fails😅
I really enjoy watching your methodical approach to dialing in these processes.

Thanks! thought it might be interesting, instead of just sharing the last final successful part after all trial and error :)
Great content, thanks for sharing!!
the trick of using polyurethane as a reference, fabulous, I didn't fall for it. My line of work was based on an epoxy mold with a very thin internal layer of silicone (an error) because I thought that it would not be able to demold well. and a counter-mold or male also made of silicone (error) since the pressure exerted did not reach well. I think that the pieces with carbon sheet you have done by cutting the pieces with preg or with unsaturated sheets of epoxy and then you have compressed them. Congratulations master Libeert
Brilliant. Thanks.
Great content as always, please make more videos I am still in the learning phase. Still loads to learn, but videos like these give me ability to learn🎉

Can we use polyurethane mold for forging using epoxy ?
I have a question, I have a part that I am wanting to make out of carbon fiber. I am having a hard time figuring out how to build a mold for it, because the piece that I am trying to make does not have a male and female end. Do you have any ideas or suggestions on building for a solid unit?
For my master's thesis I am trying to develop a guide to forged carbon for the DIY/ maker level. For this I am staying within the realm of 3d printing (fdm and SLA). Have you found any efficient ways of sanding/ smoothing your molds before casting them? As the mold release is one of the biggest hurdles I am trying to overcome. Also mixed wall thickness in parts, I think I am going to test dividing the parts into sections as to get a more even distribution of fibers.

Super cool masters topic mate! Best of luck. I for one would love to read it when you publish.
I am not sure if I havent overheard the information, but why you didnt use solely the 3D printed part as a mold?
zeer informatief! bedankt voor het plaatsen van deze video. maar eens gaan kijken naar een 3D printer.
About balloons: I've been making prepreg CF tubes; using flexible plastic tubes inside that project out through the vacuum bag. A pain because of all the sealing you need to do with the vacuum bag. But, if you could find a balloon that survived to 120deg (required for the prepreg) you could partially inflate it, leave it completely in the vacuum bag, and like you showed, the vacuum would suck it up against the inside surface. Latex balloons did not survive my oven tests.

You can make these bladders with silicone, only downside is they don't last long with epoxy resin 🙂

From what ive read online 25-30% fiber to PU ratio created the strongest parts. So your ratio is right on

correct :)
how you did the weaved part: piece of cloth in the bottom, chopped fiber on top and finished with another piece of cloth on top then pressed ?

Did you not watch the Easy Composites video on this topic? A lot of the mistakes made were covered in their excellent tutorial ;-)

I've seen it, they mostly just share the part of success, nothing wrong with that! I took another approach by replicating all the errors and approach to success in my video's as well :)
Have you ever tried to put the epoxy bucket in a small ultra sonic cleaner filled with water? It should eliminate all the bubbles.

Put the entire mould in the vakuum while the epoxy cures.
