.A fiberglass composite is composed of a matrix of vinyl ester and reinforcing fibres of Eglass. The volume fraction of E-glass is 40%. The remainder is vinyl ester. The density of the silicone epoxy is 1.04 g/cm3 , and its modulus of elasticity is 4.60 GPa. The density of E-glass is 2.60 g/cm3 , and its modulus of elasticity is 76.0 GPa. A section of composite 2.00 cm x 25.00 cm x 200.00 cm is fabricated with the E-glass fibres running longitudinal along the 200-cm direction. Assume there are no voids in the composite. Determine the a. mass of silicone epoxy in the section, b. mass of E-glass fibres in the section, and c. the density of the composite d. the modulus of elasticity in the longitudinal direction of the glass fibres e. modulus of elasticity in the perpendicular direction to the glass fibres. f. if E-glass fibres are replaced with carbon fibres having density of 1.75 g/3 and modulus of 332 GPa, what would be effect on weight to modulus ratio in comparison to composite containing E-glass fibres in same volume fraction?
