An aligned short fiber composite consists of 40 vol. % carbon fibers of length 2 mm and diameter
7
um in a polycarbonate matrix. The tensile strength of the fibers and the shear strength of the
fiber-matrix interface are 2.5 GPa and 12.5 MPa, respectively. Estimate the longitudinal tensile
strength of the composite given that the stress on the matrix at the failure strain of the fibers is 30
MPa. Determine Verit and Vmin for this composite. The strength of polycarbonate matrix is 0.075
GPa​
