A characterization program was conducted on a filament-wound composite of an aramid fiber in a room-temperature-curable epoxy matrix. The room-temperature longitudinal tensile properties of the composite are quite good and show improvements over those of an earlier composite made from the same fiber in a moderate-temperature-curable epoxy. As is typical for all aramid/epoxy composites, the transverse tensile ultimate strength and strain are low. Ultimate strengths at temperatures above and below room temperature differ only slightly from the room temperature values. The only significant temperature dependence of strength appears as a reduction in transverse tensile strength at 54/sup 0/C. Also, a change in thermal properties occurs above about 50/sup 0/C. Therefore, the potential user of this composite system should place only limited demands on the transverse tensile ultimates and the property changes evidenced above 50/sup 0/C should be considered carefully if any use at elevated temperatures is contemplated.
