Question

The table below is providing you with the information about a continuous and aligned carbon fiber-reinforced epoxy composite: Volume fraction Modulus Tensile strength Yield strength Failure strain Carbon fibre 42 220 GPa 3.2 GPa --- 1.45 % Vol % Epoxy Matrix 58 2.8 GPa 0.21 GPa 0.13 GPa 7.51% Vol % (a) Calculate the modulus of elasticity of this composite in the longitudinal direction. (b) Calculate the modulus of elasticity of this composite in the transverse direction. (c) Calculate the tensile strength in the longitudinal direction (Hint: the failure of fiber is the onset of composite failure). (only enter your final answer to each section. Do not write the entire calculation - You will get extra time after the quiz to upload your calculation methods on iLearn).
