It is necessary to fabricate an aligned and discontinuous glass fiber–epoxy matrix composite having a longitudinal tensile strength of 1200 mpa using a 0.35 volume fraction of fibers. compute the required fiber fracture strength, assuming that the average fiber diameter and length are 0.015 mm and 5.0 mm, respectively. the fiber–matrix bond strength is 80 mpa, and the matrix stress at composite failure is 6.55 mpa
