Question 1 A continuous and aligned glass fibre-reinforced composite consists of 40 vol% of glass fibres having a modulus of elasticity of 69 GPa and 60 vol% of a polyester resin that, when hardened, displays a modulus of 3.4 GPa. (a) Compute the modulus of elasticity of this composite in the longitudinal and transverse directions. [5 marks] (b) If a stress of 50 MPa is applied in the longitudinal direction of a composite sample with a cross-sectional area of 250 mm, compute the magnitude of the load (in N) carried by the fiber and matrix phases respectively. [6 marks] (c) If a stress of 50 MPa is applied in the transverse direction of a composite sample with a cross-sectional area of 250 mm, determine the strain that is sustained by each phase. [7 marks] (d) If half of the volume of the glass fibres is replaced with elution fibres having a modulus of elasticity of 400 GPa. what will be the modulus of elasticity of the new composite made of three phases (glass, carbon. and polyester) in the longitudinal and transverse directions?
