Question:

It is desired to fabricate a continuous and aligned glass fiber-reinforced polyester having a tensile strength of at least 1400MPa (200,000 psi) in the longitudinal direction. The maximum possible specific gravity is 1.65. Using the following data, determine if such a composite is possible. Justify your decision. Assume a value of 15MPa for the stress on the matrix at fiberfailure.
