Effect of a Viscoelastic Interface on the Transverse Behavior of Fiber- Reinforced Composites

Abstract

In this paper we investigate the effect of an inelastic interface layer on the mechanical behavior of a transversely loaded fiber-reinforced composite. A simple linearly viscoelastic model is used to characterize the stiffness and viscosity of the interface separating the fiber and matrix phases. The mechanical response is obtained using the finite element method and calculations are carried out for a unit cell in a periodic array of hexagonally packed fibers. An approximate representation of the time dependent macroscopic behavior of the micromechanical perspective, the influence of interfacial stress relaxation on the stress fields in the matric material contiguous to the interface is examined.
