i know manufactures spend tons of money on crumple zones and etc to make the cars safe. How does the CF hoods and other body parts do in crashes? They follow the crumple zones? They just crack? Or just go through the cabin?!?!?!

 

very good question...........you don't want to experience yourself

 

carbon fiber is strong, but very brittle similar to fiberglass. In an accident it will splinter and break, unlike metal which will bend and absorb more of the impact energy by deforming.

 

depends on the resin mixture, weave of the CF, and the layers..

in most frontal accicents i've seen with CF, the hood does a good amount of flexing and typically will bow.. of a collision i've seen the hood was the only thing intact... as for the front bumper- it will most likely shatter.. CF will take a bigger hit to completely shatter while fiberglass counterparts take less force... a shattering body piece isnt necessarily bad- since this is how it will dissipate the energy from the impact, rather than bending and deforming like metal... hatch, i dunno... but i'm assuming it will bow like the hood will, your glass would probably pop off and/or shatter as well.
