Suppose we have a 2D fiber reinforced composite material. The fiber has modulus / = 100 GPa and Poisson's ratio / = 0.33. The matrix modulus 0 = 10 GPa and Poisson's ratio 0 = 0.28. (a). Calculate the longitudinal modulus ( , the transverse modulus ) , Poisson's ratio () and the in-plane shear modulus () of the composite given a fiber volume fraction of 20%? (Use rule of mixture and Reuss model)
