fiber reinforced composites / mechanics

P3.19. A 500 mm long × 25 mm wide × 3 mm thick composite plate contains 55% by weight of unidirectional continuous T-300 carbon fibers in an epoxy matrix parallel to its length 1. Calculate the change in length, width, and thickness of the plate if it is subjected to an axial tensile force of 75 kN in the length directiorn 2. Calculate the change in length, width, and thickness of the plate if it subjected to an axial tensile force of 75 kN in the width direction Assume that the density, modulus, and Poissons ratio of the epoxy matrix are 1.25 g/cm3, 3.2 GPa, and 0.3, respectively
