A glass was developed which had a forty-five per cent higher modulus of elasticity than the commercial glass used in the fibrous glass industry. Glass filament strands of this glass were produced at a rate of several pounds per hour from a single fiber-forming position and these strands were twisted and plied into yarns for weaving. 181-style cloth was woven, heat cleaned, and finished for the preparation of glass-plastic laminates. Strength modulus of elasticity properties of laminates tested under standard conditions, and after fluid and thermal exposures, are reported. Author-PL.
