With or without resin, it is not true. The strength of E-glass (3.45 GPa) and carbon (3.53 GPA for carbon T300) are virtually identical. Carbon is lighter $ 1.75 g/cc vs. 2.5 g/cc for glass. Some carbon
If all you want is the load at which the first crack occurs in the first lamina to crack, which is called first ply failure (FPF), then you can use max. stress but you have to adjust the strength values
The density of common glass http://hypertextbook.com/facts/2004/ShayeStorm.shtml varies from 2400 to 2800 kg/m^3 (compare with water at 1000 kg/m^3, which is the same as 1 kg/liter). The weight
I don't expect any change from the type of glass, is everything else is the same, because the stiffness and strength of the fiber does not play a (significant) role on the compression strength. I say significant
Obviously if the fiber-matrix adhesion were to be very poor it would affect the compresion properties E and F1c but with normal fibers and polymer matrices, when the fibers have the coorect sizing for
