The Mechanical Response of Random Swirl-Mat Polymeric Composite

Abstract

This article concerns the mechanical response of random glass fiber strand swirl-mat/urethane matrix composite under static and cyclic loads as well as under elevated temperatures. The article presents an extensive amount of experimental data as well as predictions based upon a coupled damage/viscoelastic constitutive formulation generated specifically to model the behavior of the material at hand. Damage evolution relations are derived from an empirical relationship. This work extends previously published results.
