Quantitative Measurement of Void Content in Glass-Filament-Wound Composites and Correlation of Interlaminar Shear Strength with Void Content.

摘要

Microvoid content (< 1 volume %) of glass-filament-wound epoxy composites was determined by a precise statistical optical-counting technique. Regression correlation analyses established that a linear inverse relation existed between the interlaminar shear strength and the microvoid content of NOL ring composites and indicated that reducing the microvoid content to <0.5 volume % did not give a corresponding gain in interlaminar shear strength.
