Exploratory Investigation of Two Resin-Matrix Composites Subjected to Arc-Tunnel Heating,

Abstract

Flexure and short-beam shear specimens of a graphite-epoxy and a graphite-polyimide composite material were tested in an arc tunnel environment. The materials were subjected to seven heating rates from 12.5 to 308 kW/m2 for test times from 5 to 1000 seconds. The temperature response of the specimens was measured and the strength degradation caused by the various heating environments was determined.
