Simulation of Time-Dependant Deformation of Polymer Matrix Composites Based on Short-Term Data

Abstract

This paper presents an effort for simulating time-dependant deformation behaviour of polymer matrix composites analytically and experimentally. The proposed models were developed on the basis of the classic lamination theory and the viscoelastic approach with consideration of the anisotropic deformation of fibre reinforced polymer (FRP) composite materials. A series of shortterm creep and recovery tests were conducted to provide the basic material properties and to verify the predictive models. It was found that a fairly good agreement has been achieved between the proposed models with the creep testing data of a cross-ply carbon fibre/urethane resin composite laminate under different loading orientations.
