Q4: A continuous and aligned fiber-reinforced composite produced consisting of 30 vol% aramid fibers and 70 vol% of a poly carbonate matrix; mechanical characteristics of these two materials are as follows:to be Also, the stress on the polycarbonate matrix when the aramid fibers fail is 45 MPa (6500psi). For this composite, compute (a) the longitudinal tensile strength, and (b) the longitudinal modulus of elasticity
