Abstract

The aim of this study is to investigate the experimental and numerical characterizations of the glass/epoxy composite plates at room temperature (approximately 20 degrees C) and high temperatures (40 degrees C, 60 degrees C, 80 degrees C, and 100 degrees C). Two stacking sequences were selected as [0/90/0/90](S) and [0/90/45/-45](S). Numerical analysis was carried out using 3DIMPACT finite element code. The maximum contact force between the impactor and the composite plate, the maximum deflection at the center of the composite, and the percentage of damage area versus impact energy were drawn. Overall damage patterns were found using a light table and obtained by 3DIMPACT code. The numerical predictions showed good agreement with the experimental results.
