A unidirectional discontinuous fiber lamina contains T-300 carbon fiber in an epoxy matrix. The fiber aspect ratio (l_f=d_f) 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 E_m
= 2.07 GPa and n_m
= 0.45. If the fibers are misaligned by 108 with the uniaxial loading direction, how would these elastic constants change?
