A unidirectional carbon-fiber-epoxy-resin composite contains 68 percent by volume of carbon fiber and 32 percent epoxy resin. The density of the carbon fiber is 1.79 g/cm³ and that of the epoxy resin is 1.20 g/cm. (a) What are the weight percentages of carbon fibers and epoxy resin in the composite? (b) What is the average density of the composite?
