Static and Cyclic Compressive Fatigue of Thermoplastic-Matrix Composite in Ambient and Moisture Environments

Abstract

Advanced fiber-reinforced thermoplastic-matrix composites are being considered for many advanced engineering applications. Among various issues involved in these applications, deformation and failure behavior of the composites under static and cyclic compressive loading in ambient and moisture environments are significant concern. In this study, a graphite-fiber/polyamide thermoplastic (AS4/J1) composite system is considered. Monotonic and cyclic fatigue compressive loadings are applied to the composite in ambient and moisture environments. The objectives of this research are to study: (1) compressive fatigue strength and failure modes; (2) compressive fatigue damage process and associated property degradation; (3) effect of water absorption on compressive fatigue failure behavior; and (4) effect of lamination parameters on compressive fatigue properties.
