Abstract: The object of investigation is fractoluminescence induced by the blow of a steel striker on plates made of poly(phenylene sulfide) and carbon-iber-einfor ced poly(phenylene sulfide). It is found that fractoluminescence shows up as a series of bursts several tens of microseconds long. Simultaneously, microcracks develop on the surface. It is assumed that the bursts are caused by microcracking. The linear size of the cracks is estimated to vary from 0.2 to 10.0 $\mu$m. The crack size distribution obeys a power law. In the composite, the amount of cracks is an order of magnitude smaller than in the poly(phenylene sulfide) and the crack size distribution is somewhat broader because of a larger fraction of large cracks.
