But sure you can lay up a nosecone and cure it in less than one week.
But firsst you need to understand why your calcs and simulations did not translate to realworld results..then you may decide to alter fibre angles or plies or what about manufacturing issues? Before changing the material spec you´d surely first check all proceedures and curing ovens ,shelf life ,storage conditions you name it and THEN start modifying the homologation part.

Consequently, just increasing strength won't do you much good in those test. You need the parts to break, but they need to break in a specific way that maximizes energy dispersion. Or rather, a way that disperses energy to a level so the part complies with the regulations.
Slap on some carbonfibre layers and you run the risk of having the part snap in pieces instead of disintegrate gradually.
Thanks that does make more sense now, hopefully they will have a better chance next time round.
