Micromechanics Modeling of Long-Term Interlaminar Properties of Woven Fabric Polymer Composites

Abstract

The objective of the paper is to study the longterm interlaminar properties in woven fabric polymer composites using micromechanical models. Characterization of the viscoelastic behavior of a five harness satin woven-fiber cross-ply composite laminate is presented, taking into consideration the weave architecture and time-dependent effects. The classical lamination theory model proposed by Raju and Wang is adapted to include the in-plane elastic behavior of woven fiber composites. For the matrix-dominated out-of-plane response, a viscoelastic creep model is developed based on Schapery's nonlinear viscoelastic constitutive law. In addition, physical aging of the matrix has been included in the model using the effective time theory proposed by Struik. Furthermore, the time dependent out-of-plane behavior is predicted using a two-dimensional micro-mechanical model.
