A fiberglass composite consists of epoxy matrix reinforced with randomly oriented and uniformly distributed E-glass fibers. The moduli of elasticity of the glass fibers and the epoxy are 65 and 7 GPa, respectively. If the volume percentage of fibers is 33%, and the fiber efficiency is 0.2, calculate the modulus of elasticity of the fiberglass.
