The properties of unidirectional fiber reinforced polymer composite laminate are given as: Elasticity modulus E (GPa) Shear modulus G(GPa) Fiber (E1f)=252 (E2f)=30 25 0.32 Matrix 3,8 2 0.28 Poisson's ratio v Please make below calculations with the assumption of no void content and fiber volume fraction of 0.6. (a). Calculate the composite longitudinal modulus, Poisson's ratio, transverse modulus, and in-plane shear modulus. (b). Under a longitudinal force on the composite laminate, determine the ratio of axial forces shared by fibers and matrix. (c). Consider the cross section of fibers as circular and determine the maximum possible composite longitudinal modulus, Poisson's ratio, transverse modulus, and in-plane shear modulus. (d). Compare the elastic moduli of the composite laminates in Problem #2 and Problem #3. Please explain the differences and the reasons for those differences. (e). Calculate the composite longitudinal modulus, Poisson's ratio, transverse modulus, and in-plane shear modulus with Halpin-Tsai equations by taking a fiber volume fraction of 0.6. Also, take the fiber cross section as circular in a square array. Compare the results with previous results
