Abstract

The performance of SRIM (Structural Reaction Injection Molding) composites constructed from a thermal spray preform is analytically assessed. A finite element model has been developed with a nonlinear constitutive response to understand fiber/fiber and fiber/matrix behavior under thermomechanical loads. A one dimensional transient heat transfer problem is solved and used to simulate the thermal gradient of the part during processing. The solution from the heat transfer problem is used in the finite element model where cooled down from processing to room temperature provides the loading. Initial results indicate that residual stresses in the matrix are of a substantial tensile magnitude and produce damage in localized areas. Introduction As more economical manufa
