A Characterization of Dexter Hysol's Modified Acetylene-Terminated Bisphenol-A Prepreg System: XAS/AF-8

Abstract

The objective of this research effort is to characterize an advanced composite prepreg system. The material under consideration is Dexter Hysol's modified acetylene-terminated bisphenol-A resin on continuous XAS-type graphite fibers. Hysol asserts that this modified composite system retains the 400-425 F use temperature associated with state-of-the-art acetylene-terminated resin prepreg systems while achieving a 64% increase in Mode I fracture toughness. Our investigation shows that although the ductility was improved, other mechanical properties were severely degraded when test coupons were evaluated at 350 F and saturated with water.
