There is a seperate aerospace grade of carbon fiber for those applications.
The only one I know of that is different is Fondriest, who advertise the use of F1 carbon fiber- of much higher quality than the normal sporting goods grade cloth. I don't know if this is aerospace or not but that is the only one that differs from the majority of CF bikes that I know of.
