A composite of polycrystalline spinel (Young's modulus = 277 GPa) and aligned continuous Kevlar fibers is desired in order to increase the capacity of the spinel to withstand impact. Kevlar fibers have a tensile strength of 3.6 GPa and a Young's modulus of 125 GPa. For a desired composite with Young's modulus of 200 GPa, what is the fiber volume fraction? Use isostrain condition.
