Abstract :The behaviors exhibited by materials used in military and civilian daily applications in response to ballistic impacts constitute an important field of study. These behaviors have been investigated experimentally on composite plates with different configurations. For this purpose, Para-Aramid (Kevlar)/epoxy and Para-Aramid (Kevlar)/Glass hybrid composite plates with two different configurations were produced. Specimens obtained from these plates were subjected to tests at velocities corresponding to armor levels IIIA, IIA, and II. As a result of the tests, the effects of the velocities on the target specimens were compared. At the same time, the deformations on the plates were also examined. The study, conducted at three different velocities, yielded positive results from the Para-Aramid (Kevlar)/epoxy composite in the level IIA test, while negative results were obtained from the two hybrid plates. In the levels II and IIIA velocity tests, deformations were observed in the composite plates. Matrix cracks and fiber breakages were detected in the deformations obtained.
