Hey i want to make a Seat-holder (strut-structure) for a Racekart.
I found someone who made those but he doesnt seem to reply (or just dont wanne tell me) how you can do that.
I see only 2 ways to do this sofar:
1. Make 2 halfs along the corpus and glue them together (maybe with a extra carbon layer afterwards so you have no scars?)
2. Have a core made of foam inside, seal it off so its not just expanding with the vakuum and make it dissolve somehow

Is there any other way? His parts looks just perfect.
I dont want to skin - just to make this clear
Both ways i know dont really please me. First one lowers the strengh significantly and second one doesnt feel like the right thing to do and sounds kind of wasteful

To REALLY make a part better in composite you design it around your material not copy what someone has done in steel/Ali
You can make this part stronger and lighter but not if you copy a steel form
P.s he's drilled a hole,or it was already there from internal moulding or bladder an he's secondary bonded a Ali insert in
