For a continuous unidirectional fibre$-$reinforced composite, the modulus

of elasticity in the longitudinal $($fibre$)$ direction is $37\mathrm{.}5$ GPa and the

modulus of elasticity in the transverse direction is $6\mathrm{.}6$ GPa. If the fibre

volume fraction is $0\mathrm{.}32,$ determine the modulus of elasticity of the fibre

and matrix phases
