Doug, I live in Hurricane, WV and currently I'm
completing construction of a Lancair IVP turbine for a
customer. I've been working on this aircraft in
Summersville, WV full time for the last 2 years.
Generally speaking the parts I make in carbon fiber
are half the weight of glass parts or less. The parts
are alway stronger as carbon is 5 times the strength
of S-glass. If you get close to WV, give me a call. I
welcome visits from homebuilders anytime!!!

It is not accurate to say it is five times the strength. It might be only
twice the strength. The stiffness might be five times however.

A very complex subject and a lot depends on the lay-up. Vance on here
has designed several well known home built kit aircraft using composites.
I recommend Composites Basics by A.C. Marshal. For vacuum bagging, repair
of honey comb structures and heat cure.... Advanced Composites by Cindy
Foreman ISBN 088487 -316-1.

Composites Basics by A.C. Marshal says that hand laid wet carbon and glass
have identical tension and compression.

Kevlar is about 60% stronger in compression and 12.5% in tension.
