Q2: A fiberglass composite consists of a matrix of vinyl ester and reinforcing fibers of E-glass. The volume fraction of E-glass is 30%. The density of the vinyl estiser 0.882 g/cm³, and its modulus of elasticity is 3.6 GPa. The density of E-glass is 2.6 g/cm³, and its modulus of elasticity is 76 GPa. A section of composite 1 cm by 25 cm by 2 m is fabricated with the E-glass fibers running longitudinally in the 2000 mm direction. Determine: (a) The masses of vinyl ester and E-glass fibers. (b) The density of the composite. (c) The composite modulus of elasticity in the longitudinal and the perpendicular directions of the glass fibers.
