Mechanics of Failure of Composites.

Abstract

Experimental and theoretical studies are presented on the influence of composite microstructure on the transverse tensile and shear strength of graphite and glass fiber- reinforced composites predicted from previously formulated failure criteria. Sensitivity of the transverse and shear strength to variations and errors in fiber content, void content, resin content, specific gravity of composite, and properties of the fibers and the matrix is investigated. In conjunction with these studies, an approximate solution is presented for the residual thermal stresses in composites consisting of orthotropic fibers and isotropic matrix, the properties of which are temperature-dependent. Theoretical and experimental studies are also presented on compressive strength and failure modes of unidirectional composites and graphite-epoxy and graphite-phenolic composites.
