Hey guys,

We have just designed and 3d printed a prototype of a brake duct we want to use but need to make it out of carbon.
Now, i have no composite experience what so ever! So whats my first step? Or any one local to me (SG80NZ) fancy a challenge?

Not too complex of a part. Prepreg would certainly be beneficial to get an even finish on the part, and will have a higher glass transition temp (generally speaking). What kind of temperatures will that thing see?
If you persue it, i would print half the negative mould so you have a well defined split line, make the first half on the mould like this, rip off the printed half and laminate the second half of the mould. Check the easy composites youtube channel for details on mould making.

We see temps of around 500' on the disc and 260' at the caliper. This runs pretty close to the disc but will have air flow through it for the most part, and hopefully our disc temps will be reduced significantly with nice ducting installed. Will check out the youtube channel! 
 This is a skill that we could do with in the race shop!
