Sorry for not following the thread in detail,but will post a few short comments on carbon fiber and E/G.
Carbon fiber will add to the stifness of E/G,but has very poor vibration damping.C/F is like steel and rings like a bell.The jist of the thread was to use E/G as a vibration damper.Steel tubes filled with E/G would dampen vibrations much better than C/F.On another note,Kevlar has vibration damping qualities.In aircraft parts,Kevlar absorbs impacts and deforms similar to aluinium.If you need to increase stifness,Kevlar is a better choice than C/F
