$2.$ For a continuous and aligned fiber$-$reinforced composite, the modulus of elasticity in the longitudinal direction is $33\mathrm{.}1$ GPa and the modulus of elasticity in the transverse direction is $3\mathrm{.}66$ GPa. If the volume fraction of fibers is $0\mathrm{.}30$ and the modulus of elasticity for the matrix phase is $2\mathrm{.}6$ GPa $,$ what is the modulus of elasticity for the fiber phase?
