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.....

             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.....

                 During use with loads of airflow is probably really not critical. However, bring the car to a stop after some laps and having the brake system heat soaking everything around it will certainly warp a....

     If these are one-offs you could sand the A surface smooth, use a release agent on the printed part and laminate directly to make a carbon part. Really depends on what your expectation and volume are....

             Volumes are very low, currently need 2 units, although having spares might be a good idea! Is there any youtube vids showing what you mean?

     If you only want a couple as others have said prob your 3D part down on the outside, seal an release an use that as your mould. Mark your split line an laminate one half to the line Cover a 25/ 30mm....

             All makes sense. The more i thing about it the more it makes sense to print the inner void shape and mould around that, then maybe do the flat flange as a separate piece and bond them together..?

                 Nah print the void with a flat base, or stick it onto a flat board and laminate everything in one go!

                 I'm not sure how feasible it is for you to do this but I used expanding foam to fill the inside of a 3d printed part so I could use the foam as a mold. Your shape may not allow for that though in...

                     I'm pretty sure you wouldn't be able to get the foam out in one piece due to the internal shape. But nice idea for other ideas.
