Cоmpute the lоngitudinаl tensile strength оf аn аligned glass fiber–epoxy matrix composite in which the average fiber diameter and length are 0.015 mm and 2.0 mm, respectively, and the volume fraction of fibers is 0.25. Assume that (1) the fiber-matrix bond strength is 100 MPa, (2) the fracture strength of the fibers is 3500 MPa, and (3) the matrix stress at composite failure is 5.5 MPa.
