For a continuous and oriented fiber- reinforced composite, the moduli of elasticity in the longitudinal and transverse directions are 33.1 and 3.66 GPa (4.8 x 106 and 5.3 x 105 psi), respectively. If the volume fraction of fibers is 0.30, determine the mod- uli of elasticity of fiber and matrix phases.
