(d) The average density of a carbon-fiber-epoxy composite is 1.615g/cm³. The density of the epoxy resin is 1.21g/cm³ and that of the carbon fibers is 1.74g/cm³. The tensile modulus of elasticity of the carbon fiber and epoxy matrix is 189GPa and 3.7GPa respectively. (i) What is the volume percentage of carbon fibers in the composite? (4 marks) (ii) Calculate the tensile modulus of elasticity of the composite if it is stressed under isostrain condition. (3 marks)
