The primary aim of this investigation was to establish the strength characteristics of S-glass fiber bundles and composites subject to quasi-static loading. Ten glass bundle specimens and glass fiber unilayer specimens, each containing thirty-one approximately equally-spaced fibers S-glass, 0.00485 in diameter were prepared and tested in an instron machine at three strain rates 0.0265 ininmin, 0.66 ininmin and 26.5 ininmin. Grid lines were placed on composite specimen producing interference Moire fringes with a reference master grid placed in front of the specimen. The specimens were observed photographically during deformation. Author, modified-PL.
