Solve the following problem:
Compute the tensile strength for the composite of Problem 1 assuming that all the fibers have the same tensile strength.
Problem 1: Give an approximate value for the compressive strength of an Al-Boron composite with Vf = 0.4. Aluminum 2024 has E = 71GPa, Poisson = 0.334, G = 26.6 GP a, yield strength = 76 MP a, fatigue limit = 90 MP a, elongation = 22%. Boron fibers have E = 400 GP a, ultimate strength = 3.4 GP a, Poisson = 0.25.
Note that Boron fibers tend to be perfectly straight and that aluminum has a linear shear stress-strain plot before it yields.
