Most composites are built on a sandwich core over which layers of kevlar or carbon fiber
are laid and vacuum bagged till cured. The key here is that the layers are separated so that
there is thickness between the layers under tension and those under compression with the
core taking up shear forces.
Carbon fiber is brittle, and if it was laid up as a single thin layer it has little strength, the
minute you break one fiber it will zip like zipper breaking the next thread, and the next...
The part will fail under shock loading... or even static that loads single threads to much...
Even in Formula 1 carbon fiber chassis will have a layer of kevlar to hold broken carbon
fiber together in a crash.
A properly built composite prop will be very different from a metal prop.
