Abstract
The stress-displacement relationship of the fiber during the fiber pull-out process in a fiber-reinforced composite (i.e. the fiber pull-out curve) is considered. Understanding of both interfacial debonding and friction at the debonded interface is essential in interpreting the fiber pull-out curve. The behavior of interfacial debonding, which can be unstable, partially stable or stable, is characterized in the present study. The debonded interface can be either subjected to Coulomb friction, or free of friction which is contingent upon the comparison between the residual clamping stress and the interfacial radial tension induced by Poisson's contraction of the axially tensile-loaded fiber. The important parameters controlling the characteristics of interfacial debonding and friction are studied, and various fiber pull-out curves are elucidated. ? 1991.
