A composite is made of 20 vol% uniaxially aligned continuous carbon fibers in an epoxy matrix. The axial elastic modulus of the fibers is 400 GPa, the transverse elastic modulus of the fibers is 40 GPa and the elastic modulus of the epoxy is 0.4 GPa. Calculate: (i) the elastic modulus of the composite and the ratio of stress in the fiber to the stress in the matrix when the composite is loaded elastically along the axis of the fibers (ii) the elastic modulus of the composite when it is loaded elastically in a direction transverse to the fiber axis.
