the carbon hoods on the market are not a vinyl overlay on a Fiberglass Hood
The hoods are built in a mold
first resin is applied to the mold
carbon fiber cloth is laid into the mold and then squeegeed out saturating the fabric with resin and removing off the excess.
after the top layer carbon is worked out and saturated the hoods are backed with a Fiberglass backing to add rigidity to the Hood
. More expensive hoods would use additional layers of carbon applied diagonal with the previous layer to get the strength up.
After the top skin is completed a Fiberglass underframe is bonded and the taps for the hinges are installed and a latch is installed.
carbon fiber and Fiberglass hoods are fine and not a sacrifice in saftey. The front of the car is designed to crumple in an accident and the Hood
would just spiderweb and absorb the imapct as well.
many oem vehicles use Fiberglass hoods b/c of the weight savings over steel.
