Abstract: This paper demonstrates results of an experimental study on glass/epoxy laminated composites subjected to low velocity impact at energy levels equal to 10, 15 and 30 J under variable temperatures in the range of -30°C to 23°C. The configuration of specimens is quasi-isotropic. The low temperature and its influence on the maximum absorbed energy, elastic energy, crack length and delamination are highlighted. Also, the effects of geometry index (span-to-depth) and notch orientation are studied. Failure mechanisms of specimens are examined using microscopic examinations. Results indicate that impact performance of these composites is affected over the range of temperature considered. Failure mechanism is changed from matrix cracking at room temperature to delamination and fiber breakage at low temperatures.
