Question
Can we use some sort of carbon fiber shape, carbon fiber rod, carbon fiber tube, fiber reinforced plastic, fiberglass, Kevlar, or other composite material in the structure of our Regular class aircraft?
Answer
There have been an unusually large number of questions asked in the forum recently if some type of fiber reinforced plastic material can be used in the structure of a Regular class aircraft in a certain way.

The answer is always no. Teams are not allowed to use carbon fiber tube, carbon fiber rod, carbon fiber layups, fiberglass rods, fiberglass tubes, fiberglass layups, pre-cured composite sheet or shaped material of any kind, fiberglass, Kevlar or any other type of fiber reinforced plastic not listed here in the structure of the Regular class aircraft

The sole exceptions are non-structural commercially available FRP hardware items listed in the rules: motor mount, prop, landing gear, and control linkage components.
