A metal matrix composite (MMC) is made of a 2024 Al alloy matrix and continuous boron fibers. The boron fibers are produced with a 12.5 μm diameter tungsten-wire core which is coated with boron to make a final 100 μm diameter fiber. A unidirectional composite is made of 54 vol % of the boron fibers in the Al 2024 matrix. Assuming the law of mixtures applies to isostrain conditions; calculate the tensile modulus of the composite in the direction of the fibers. [ E(B) = 379 GPa, E (W) = 410 GPa, E (Al) = 72.4 GPa]
