This is total BS, don't listen to your friend...
First off, Carbon Fiber hoods are made for racing applications, I.E. they're designed with safety in mind.
Carbon fiber is strong stuff, and, just like Fiberglass, if enough force is acing upon it, it will shatter. Force of impact will flex the carbon fiber Hood
. (like a bow or a fishing rod), when it reaches it's limits fo flexure, it shatters into many pieces. this shattering action is what absorbs the force of an impact. This is why they can make cars like the corvette, which have 100% Fiberglass bodywork.
The key is installation, the parts must be installed correctly so they bend and fracture like they're supposed to. Properly aligned, and properly torqued fasteners on hinges and latches
are a part of this.
Now, there is a possibility of the Hood
doing what your friend said, but there have to be some important conditions present for this to happen.
1) your setup doesn't have Hood
pins: if the front corners of the Hood
are not secure, the Hood
latch may break away and the Hood
flies up, and less force is absorbed. For safety, and to keep it street legal, you MUST have Hood
pins in place.
2) the winshield is gone; the windshield is stronger than that Carbon Fiber Hood
, so, it should'nt penetrate it. Also, if the Hood
is torqued down properly, it should stay connected to the firewall.
Maybe on a kevlar piece, I'd worry about that happening, since it's much tougher than carbon. Carbon Fiber and Fiberglass hoods are safe, so long as they're installed correctly and secured with Hood
It's more like the drawing below:
