The Amuse hood they make for my car has no under brace nor rain channels, but it does weigh in at something rediculously like 3lbs. That too me just seems like a sheet of CF to cover my engine bay. If it did weight 3lbs, that's a $1000/lb for this hood.
it is exactly that... a piece of carbon over your engine bay....
what fab is sayin composite parts have different tendencies... they distribute weight differently, they absorb impact differently.... and also they have different strength to wieght ratios.... and so on..
if you were to engineer a carbon part..... why would you engineer it like a steel part..... more than likely if you where to reinforce the rails of the hood to support the hinges and reinforce the hood pop..... by usinge a bi directional weave clocking at both hinges with two layers it would create an intersection at the front of the hood. i would then run the last layer at roughly parralel with the front of the vehicle. i feel this would take stress to the hood pop and direct to the rails (sides) and then on to the hinges. i dont think a 3 layer part with its orientation like this would need any more under bracing.... waste or carbon and weight. imo. of course you can calculate this and test this. many factors are now in play fabric weight... strand count and so on.
orientation or clock would look like a capitol V with a dash in it..... -V-
btw fabrik8 i looKed ate those links and was astounded..... i was making carbon parts on 2003 and buying rolls for just over 2100 shipped from china. 100 yards not feet....... damn i wish i stayed in it or had a million bux worth of carbon stashed away.... it would have been the best investment yet. gold doesnt change price like that.
