3.1 As an engineer, you are required to design an aligned carbon fibrelepoxy matrix composite having a longitudinal tensile strength of 750 MPa. Calculate the volume fraction of fibres necessary if: 3.1.1 the average fibre diameter and length are 1.2 x 10-2 mm and 1 mm, respectively. (3) 3.1.2 the fibre fracture strength is 5000 MPa. (3) 3.1.3 the fibre-matrix bond strength is 25 MPa. (3) 3.1.4 the matrix stress at fibre failure is 10 MPa. (3) 3.2 Based on fibre length and orientation, three types of fibre-reinforced composites are possible, mention three types of fibre-reinforce composites (3)
