Not long ago I saw a Youtube video that was shared on here at the Koenigsegg factory. They seemed to be using CNC milled aluminium moulds, composed of two parts, some how laying the CF inside the parts, closing the mould, and then passing a inflatable bladder through two ends.

It's difficult to describe the part and I have no drawings. However, the outer shell geometry of this glider fuselage is about right. With an opening at the front "cockpit" and at the back. In intend to create an epoxy casting of the cockpit interior and once fixed into the shell, fill with expanding low density polyurethane from the back end.
