Assume that a graphite-epoxy-reinforced plastic with longitudinal fibers contains 20% graphite fibers, which have a strength of 2500 MPa, and elastic modulus of 300 GPa. The strength of the epoxy matrix is 120 MPa, and it has an elastic modulus of 100 GPa. Find: Calculate (a) the elastic modulus of the composite and (b) the fraction of the load supported by the fibers.
