To get a decent fibre volume ratio with carbon fibre, use 1000gsm of fabric per mm of part thickness. I would also suggest to wrap the mandrel if you can as this is way easier to compact the fabric and to control the fibre orientation which is crucial for the strength of the part.

Great rule of thumb, going to try it out! I was thinking in this case since the fabric would be captive in the "tub" it would have less chance to distort as the two walls slide past each other. Great point on the strength, I focused on just getting it done and forgot to go over the specialities of working with carbon. Will cover it in more depth on the next how-to video. Thanks alot!

Damn you skipped the one part I wanted to see where you get the parts out of the mold...

My bad, was a little too violent to do with camera in the way - pliers and chisel! Will be sure to film it in the next video (going to make an X carriage for a 3d printer)

@@vapourcycles all good I look forward to your future experiments with this! I want to try this process for making electric skateboard parts.

Sounds like a really cool project! Going to look great in carbon too 🤘

pretty cool seeing the process, especially the bits that weren't working. I tried making cf handle bars the other day, what mess haha. anyway subbed, keep it up!

Trick! Sorry I missed the function of this part, what is it? I made a carbon fibre slave screw on head bolt for my”wiper snipper” grass cutter. The screw fitting that scrapes on the ground. To be honest it did good. Could of done with more curing though.😂 Straight... need it now.. extra hardener situation. I packed that stuff deep with and extra coat between a few layers. If you can add extra windings in a sequence where it’s super dooper sticky... it’s adds mega strength. Observation.👾😊🤜🏼🤛🏼🍀🍀🍀😎

Hey Steve! It has no function, beyond being an easy shape to demonstrate the process :) Sounds like you had a fun project there, probably the most advanced grass cutting mod on the planet 🤘

Why not print it in carbon?

You mean the chopped fiber one? You can't squeeze much through a printer nozzle, so you are limited to fiber size and therefore strength of the part. Also you can only print thermoplastics, which is not good if you want thermal stability. And finally this process has no layer adhesion issues - it's pretty much one solid molecule of plastic! The only thing printed carbon filled nylon has going is that you can make things hollow and therefore light, it's not in the same league on every other aspect
