Özet

The response of glass-epoxy composites to repeated impact for various impact energies ranging from 5 to 15 J was investigated. Specimens with two different stacking sequences were studied; [0/90/0/90](S) and [0/90/+45/-45](S). In addition to the room temperature, impact tests were also performed at -40 degrees C environmental test temperature for impact energy of 15 J. Contact force-deflection and energy-time curves at each test and the number of impacts to failure (N-f) were obtained for each experiment. Compression after impact (CAI) tests were also conducted to determine the residual load carrying capacity of the damaged specimens. POLYM. COMPOS., 30:1562-1569, 2009.
