A technique for microanalysis of matrix and fiber-matrix interaction during composite deformation
Abstract
Since composites deform inhomogeneously, such experimental techniques as will yield data on the response of matrix and interfacial regions to loading and deformation due to crack growth are required. Attention is presently given to the use of stereoimaging techniques to determine local strains, yielding determinations of displacements, strains, and stresses at the surface of the composite with submicron resolution. Analyses of deformation around fatigue crack tips growing in graphite-reinforced epoxy and boron fiber-reinforced titanium alloy illustrate the stereoimaging method.
