The Effects of Solvents and Stress on the Stress-Rupture Life of Glass- Epoxy Composites

Abstract

The combined effect of an active environment and stress on the survival lifeof a homogeneous epoxy resin and FRP/epoxy resin was investigated. Theactive environment was that of liquid benzene at room temperature. Tensilecreep rupture tests at different stress levels are performed for bothsamples in an inert and the active environments. The operational techniqueswhich are necessary to extend the kinetic theory of rate dependent rupture toinclude anisotropic and environmental effects are investigated. Experimentalresults showed the decrease in life is strongly dependent on the angularorientation of the composite both for the inert and active environment.
