N2 - The effects of low velocity impact on laminated composite panels are presented in this paper. In the experimental program, 16 ply, 32 ply and 48 ply quasi-isotropic laminated composite panels were subjected to low velocity impact loads. The laminates were held in a special fixture, which was designed to simulate simply supported boundaries. Impact experiments were conducted in a Dynatup low velocity testing machine where a drop-weight system was used to strike each panel at 90 degrees incidence under controlled conditions of impact velocity. The impactor used was of a constant weight and tip diameter, the impact height and hence the velocity and energy were used as variables in the study.
