A FRP composite includes 40% continuous and aligned Aramid fibers by vol-ume. The moduli of elasticity of the Aramid fibers and the epoxy resin matrix are 130 and 3.9 GPa, respectively. a. Compute the modulus of elasticity of the composite in the longitudinal and transverse directions. b. If the composite cross-sectional area is 150 mm' and a stress of 40 MPa is applied in the longitudinal direction, compute the load carried by the fibers and the matrix. c. Determine the strain sustained by each of the phases when stress in part (b) is applied.
