  1. A fiber-reinforced composite material has moduli of elasticity in the longitudinal and transverse directions of 6.9 GPa and 3.5 GPa, respectively. If fibers make up 25% of the composite volume and 56% of them are oriented in the longitudinal direction, find the moduli of elasticity of the fiber and matrix phases. Assume that all fibers not oriented in the longitudinal direction are oriented transversely.
