Abstract : Drawing of E-glass fibers for length effect study has commenced. Fibers from 994 glass composition were drawn tentatively for the same purpose. Short fiber tensile tests on fibers from S-994 strand showed considerable data scatter in contrast to previous X-994 results. Strength data fell within the strength-length envelope of X-994 fibers. Fiber slippage in gripping wax was studied critically and was found to have negligible effect on gage lengths above 0.1 cm. The increasing effect on shorter fiber lengths depends on the slope of the strength versus length curve. Analysis of failure distribution curves of X-994 fibers in the short fiber range indicates the presence of two types of defects: surface, and possibly structural. The effect on strength of the two types varies proportionally as fiber length decreases. A theoretical treatment of failure distributions resulting from mixed flaw populations supports analysis of test results. (Author)
