Time-Dependent Deformation of Stitched T300 Mat/Urethane 420 IMR Cross-Ply Composite Laminates

Time-Dependent Deformation of Stitched T300 Mat/Urethane 420 IMR Cross-Ply Composite Laminates This article concerns certain aspects of the time-dependent response ofcross-ply polymeric composites consisting of stitched graphite fiberstrands embedded in urethane resin. Experimental data were collected atseveral levels of stress and temperature, as well as at various loadorientations. The time-dependent strains were shown to consist of thesum of a fully recoverable viscoelastic component and a permanentportion, which could be expressed empirically.

Abstract

This article concerns certain aspects of the time-dependent response ofcross-ply polymeric composites consisting of stitched graphite fiberstrands embedded in urethane resin. Experimental data were collected atseveral levels of stress and temperature, as well as at various loadorientations. The time-dependent strains were shown to consist of thesum of a fully recoverable viscoelastic component and a permanentportion, which could be expressed empirically. The utility andshortcomings of the power-law creep form are being examined, suggestingthat its validity for making long term predictions may require that`short time' data must be collected over durations that exceed a certaintime-span. The article presents several results that demonstrate thepredictive capabilities of some of the formulations employed therein.
