Assume that the unit cell of a composite containing commingled filaments of E-glass and T-300 carbon fibers can be represented by a square array shown in the following figure. The radius of the E-glass filaments and T-300 filaments are 3.5x10"m and 5x10 m, respectively. The densities for glass fibers, carbon fibers, and matrix are 2.54 g/cm', 1.76 g/cm, and 1.2 g/cm', respectively. (10') 1. Determine the unit cell dimension if the fiber volume fraction is 60%. 2. Determine the theoretical density of the composite. Eglass flament T-300 flament
