5) Assume that the composite in a composite beam is carbon fiber reinforced epoxy with a fiber volume fraction of 60%. To minimize the cost, assume that the carbon fibers are being replaced by an equal volume fraction of E-glass fibers. To compensate for the lower modulus of the E-glass, the thickness of the beam is increased by 3-fold. Determine the cost savings if carbon fiber is $40/kg, E-glass is $4/kg and epoxy is $6/kg. The specific gravities of epoxy, carbon fibers and E-glass fibers are 1.25, 1.8 and 2.5 g/cm, respectively. 5) Assume that the composite in a composite beam is carbon fiber reinforced epoxy with a fiber volume fraction of 60%.
