Is this a Uni project or for commercial application?

Commercial products such as CFRP will do. Uni fibers laminate will split if alone so it is usually wrapped in +45-45 fabric. Uni Fibers...

Just using the same formal terminology as used in filament winding method and as used by Eric Sponberg, a member and contributor to this...

Vertical means 90 degree (hoop). Usually it is the 0 degree fibers that are dominant. 50 to 60%. Hand layup mast have very low modulus...

If this is a filament wound mast, then it consist of unidirectional fibers wound in three axis in a standard 20/50/30 % proportions. 90...

If you see this microcracks, you are in trouble. If none yet, do not be too complacent. Carbon fiber laminate belongs to the "brittle"...

I think you are comparing compression yield strengths, but it is necessary to instead compare the tensile/youngs modulus and compressive...

Regarding the OP's health and physical abilities, it's best to speak with his doctors, or with him directly, before assuming that at 65...

Last I checked above this is Boat Design Forums>Construction>Boatbuilding. He does not care about your X years in the boatbuilding...
