Abstract : 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 in/in/min, 0.66 in/in/min and 26.5 in/in/min). 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).
