Abstract: Triboluminescence is used to study the microcrack formation during dry sliding friction on steel of polyphenylene sulfide (PPS) and a composite material consisting of a PPS matrix reinforced with a carbon fiber fabric. It is found that, when fabric layers are parallel to the slip plane, the number and linear sizes of microcracks are larger than those in PPS. In contrast, when fabric layers are normal to the slip plane, the number and linear sizes of microcracks are smaller than those in PPS. These effects are explained by the formation of boundary layers in the matrix in which molecules are oriented parallel to the axis of fibers in the fabric.
