Abstract
This paper investigates the effect of temperature on hybrid woven composite panels (100mmx100mmx25mm) which underwent drop-weight impact at five different test temperatures: -60°C, -20°C, room temperature, 75°C and 125°C. The studies were conducted by using experimental and 3-D dynamic finite element approaches. The specimens tested were made of plain-weave hybrid S2 glass and IM7 graphite fibers imbedded in toughened epoxy (cured at 177°C). The composite panels were impacted using an instrumented drop-weight impact tester. The time-histories of impact-induced dynamic strains and impact forces were recorded. The damaged specimens were inspected visually and using the ultrasonic C-scan method.
