A continuous and aligned fiber-reinforced composite is to be produced consisting of 45 vol% aramid fibers and 55 vol% polycarbonate matrix; the mechanical characteristics of these two materials are as follows: Modulus of Elasticity [GPa (psi)] Tensile Strength [MPa (psi)] Aramid fiber 131 (19 x 106) 3600 (520,000) Polycarbonate 2.4 (3.5 x 105) 65 (9425) The stress on the polycarbonate matrix when the aramid fibers fail is 35 MPa (5075 psi). For this composite, compute the longitudinal tensile strength. Express your answer in MPa to four significant figures. Do not include the units. Answer:
