You are developing a continuous and oriented fiber reinforced composite. You need the material to have a modulus of elasticity in the longitudinal direction is 19.7 GPa and in the transverse it is 3.66 GPa. The volume fraction of fibers is 0.25 will be. Find the modulus of elasticity of the fibers and matrix that you should look for to meet these criteria.
