1. Is it possible to produce a continuous and oriented aramid fiber-epoxy matrix com- posite having longitudinal and transverse moduli of elasticity of 35 GPa (5 X 106 psi) and 5.17 GPa (7.5 X 105 psi), respectively? Why or why not? Assume that the elastic modulus of the epoxy is 3.4 GPa 14.93 X 105 psi).
2. For a continuous and oriented fiber- reinforced composite, the moduli of elasticity in the longitudinal and transverse directions
(b) Calculate the actual loads carried by both fiber and matrix phases.
(c) Compute the magnitude of the stress on each of the fiber and matrix phases.
(d) What strain is experienced by the com- posite?
