Question: (a) Write an expression for the modulus of elasticity for a hybrid composite in which all fibers of both types are oriented in the same

(a) Write an expression for the modulus of elasticity for a hybrid composite in which all fibers of both types are oriented in the same direction.

(b) Using this expression, compute the longitudinal modulus of elasticity of a hybrid composite consisting of aramid and glass fibers in volume fractions of 0.30 and 0.40, respectively, within a polyester resin matrix [Em = 2.5 GPa (3.6 ( 105 psi)].
