Abstract : The room-temperature tensile characteristics of boron-filament--epoxy-resin composites have been determined by utilizing ring and belt specimens. The effect of low to elevated temperatures on rings and cyclic loading on belts was also investigated. An analysis of the tensile strength of the monofilaments used for the fabrication of the composite specimens is included. In addition, a theoretical analysis of the bending stresses inherent in ring tensile testing is presented. The filament strength in the composite NOL ring was 85 percent of the average monofilament strength.
