A unidirectional discontinuous fiber lamina contains T-300 carbon fiber in an epoxy matrix. The fiber aspect ratio (lf=df) is 50, and the fiber volume fraction is 0.5. Determine the elastic constants E11, E22, n12, n21, and G12
for the lamina. For the matrix, use Em
= 2.07 GPa and nm
= 0.45. If the fibers are misaligned by 108 with the uniaxial loading direction, how would these elastic constants change?
