A fiberglass composite is composed of a matrix of vinyl ester and reinforcing fibers of E-glass. The volume fraction of E-glass is 35%. The remainder is vinyl ester. The density of the vinyl ester is 0.882 g/cm3 , and its modulus of elasticity is 3.60 GPa. The density of E-glass is 2.60 g/cm3 , and its modulus of elasticity is 76.0 GPa. A section of composite 1.00 cm by 50.00 cm by 200.00 cm is fabricated with the E-glass fibers running longitudinal along the 200-cm direction. Assume there
\r\nare no voids in the composite. Determine the (a) mass of vinyl ester in the section, (b) mass of Eglass fibers in the section, and (c) the density of the composite
