Abstract : Reduction of the humidity to a dew point of -45 F in the atmosphere surrounding E-glass fibers as they were drawn produced no consistent improvement in the glass stress calculated from split ring tensile tests of reinforced epoxy rings made from the monofilament. It is suspected that other factors including storage and testing conditions for the rings may be of over-riding importance in determining strength, particularly where such a small cross-section with one machined surface is involved. Daily fiber and test ring production rate was increased by the installation of automatic, timeactuated controls on the furnace heating circuits. Preparations are being made to test individual filament tensile strength for comparison with the calculated strength obtained in filament wound composite rings. (Author)
