Question 5. A metal-matrix composite (MMC) is made of a 6061-Al alloy matrix and continuous boron fibers. The boron fibers are produced with a 15.5 ụm diameter tungsten-wire core that is coated with boron to make a final 107 µm diameter fiber. A unidirectional composite is made with 63 vol % of the boron fibers in the Al 6061 matrix. ASsuming the law of mixtures applies to isostrain conditions, calculate the tensile modulus of the composite in the direction of the fibers. Data are Eß = 370 GPa, Ew = 410 GPa, and EAi = 70.4 GPa.
