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

Machined tooling with an internal pressure bladder.

I agree with hanaldo, that internal bladder moulding would be the optimal route to go. However I think those are made positive over a core. First the tube diameter gets bigger towards the knots. And...

Thank you for the for the detailed answer! Perfectly fits what i see too but since there is a metal plug on each side of the tubes with a tiny hole i dont see where he got that bladder out Edit:...

You could just use PVC foam as your shaped core. Laminate the carbon and just leave the foam in there, it's really light and only makes the part even stronger.

it could be a soluble core, have a look at the stratasys range of materials like SR130. The core is 3d printed,wrapped in PTFE tape then the carbon and placed into a clamshell tool. Once the part is....

Braid looks tidy but there looks to be a VERY thick resin/lacquer coating

He is making high end parts for Race-karts only as far as i know (not his fulltime job)

You could also use a polystyrene foam as a core to form the tube, this foam is then dissolved with acetone to get a hollow tube.

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.....
