    Abstract

    The tensile failure stresses of polycrystalline alumina filaments (DuPont Fiber FP) were experimentally measured and statistically evaluated for several different gage lengths 1.27, 2.54, 5.0, 7.6, 12.7, and 25.4 cm. Static and dynamic tensile elastic moduli results also are reported, and a method for determining the true fiber gage length is described.

    Using a two-parameter Weibull distribution function to describe the in situ filament stresses, a statistical failure mode analysis for composites gave excellent agreement between theoretical predictions and published tensile strength data on cast Fiber FP/aluminum and Fiber FP/magnesium.
