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. (d) If the tensile strength of the glass fibers, is 1 GPA and the tensile strength of the epoxy matrix is 60 MPa, find the tensile strength of the composite in the longitudinal direction.
A composite material consists of 60% glass fibre by volume (V₁ = 0.6). Half of the fibre is in unidirectional (0°) roving form and the other half is continuous fibre (0°, 90°) mat. The matrix is polyester. The properties of the constituent materials are shown in Table 4. Table 4 Density (Mg.m³) Tensile modulus (GPa) Tensile strength (MPa) Fibre 2.6 69 1200 i.
