k Group: Forum Members Posts: 36, Visits: 664	Has anyone succeeded in making their own carbon fiber brake rotors and bads for a carbon on carbon braking system for a race car? ...What kind of process did you follow for making them? Any special considerations? How did you test them? I'm just curious to know if it would be as straightforward as it seems it would be or if there is some "secret magic" that prevents mere mortals from attempting the feat. Thanks

Takes about 6 weeks to grow a disc. Modern discs have slightly diffrent characteristics as they alter the gasses used an the various quantities Originally the discs that were used in f1 were the off cuts from the plane industry. F1 discs were the centres that were cut out off the discs for Boeing 747

But I certainly wouldn't look into trying to make some. I bought a couple to make into light fitting bases and they were relatively cheap.

Hi mate rumour has it the boys at ks tried to make discs with high temp pre preg Didn't end well surprisingly

Yeah, I guess it problematic post curing the discs to 1000 dec C :-)

As a hobbyist you will not get the materials or the equipment. The process I was involved in was this: resin impregnated fibres (not epoxy) were placed into a mould and baked. This burned the resin, leaving only graphite. after this the now porous material was infused with resin and baked several times to get rid of the porosity. So in the end you get a carbon fibre reinforced graphite material, which is much more heat resistant than any crp. So no, it is absolutely not a straight forward process.
