Low temperature effect on single and repeated impact behavior of woven glass-epoxy composite plates

This study deals with the determination of the response of woven glass-epoxy composites to the single and repeated impact loading at room temperature and at −50℃. Single impacts were performed at various energies up to perforation took place and the characteristics such as contact force, contact duration, deflection, and absorbed energy were obtained. In addition, some low energy values were selected for the repeated impact tests. The maximum contact force and absorbed energy versus repeat numbers were given. It was found that temperature is extremely important for determining the response of the composite subjected to single and repeated impact loadings.
