摘要

This paper demonstrates results of an experimental study on Kevlar/fiberglass composite laminates subjected to impact loading at variable temperatures. The effect of temperature on maximum energy, maximum impact force, and compression after impact was studied at several low velocity impact energy levels (8J, 15J, 25J). The temperatures considered were in the range of -50C to 120C. Results indicated that impact performance of these composites was affected over the range of temperature considered. Testing at ambient temperature is not fully sufficient and therefore additional testing must be performed for full understanding of composite laminate properties.
