HIGH STRENGTH GLASS FIBERS DEVELOPMENT PROGRAM
Abstract
The influence of moisture on the effective strength of E-glass fibers, both as single monofilaments and when incorporated with epoxy resin into filament-wound ring structures, was investigated. Humidity in the atmosphere surrounding the fiber was controlled during various periods in its history. Split ring tensile tests on the composites showed a definite ad vantage for the maintenance of dry surroundings throughout all processing steps. Work with single bare fibers of E-glass served to verify the importance of this stress corrosive reaction. By conducting tensile tests at liquid nitrogen temperature (-196 C), the reaction rate was reduced essentially to zero with a resulting change in average fiber strength from 507,000 psi at room temperature to 814,000 psi at -196 C. At the low temperature, 25% of the fibers exceeded 900,000 psi and values as high as 974,000 psi were recorded.
