Traditional materials are being replaced by advanced technology materials. Especially in the defense industry, aerospace and aviation, armored vehicles and automobile sector, especially in the military field, researches to increase ballistic and impact resistance and the detection of damage to the material and the optimization of new designs are focused on. Composite materials are also used in secondary structural parts of the aircraft, which are considered to be able to continue their flight partially in case of damage. A comprehensive study of the deformations that occur in the material as a result of impact is important as a contribution to the literature and as a reference for aviation maintenance personnel. In high-tech sectors, especially in the aerospace industry, composite materials with aluminum layers are preferred for payload weight compared to conventional materials. Aluminum-containing composites and aluminum-containing materials, due to their high strength to weight ratio, are vital in many sectors where payload weight is important, especially in the aerospace industry. Rubber-blend PU polymer was cured in a customized mold together with 1050 Al sheets to create the layered composite. The polymer layer was strengthened using different rows of Al wire screen. A novel approach to fabricate a reinforced composite panel in one spot was introduced. A specifically made drop weight apparatus was used to conduct a low velocity impact test. Drop weight tests were carried out at five distinct energy levels (40J, 60J, 80J, 100J and 120J) to examine the impact behavior of the specimens. Force-time histories were saved for each event. The "energy-time" and "force-displacement" variations were also obtained by kinematic analysis performed in accordance with ASTM D7136/D7136M-12 standard. No puncture occurred in any specimen. Since the specimens were layered, penetration was observed only in the top layer. In addition, the peak forces, the absorbed energy and the impact tip’s indentation are also presented. Damage to the layered composite structures after impact was investigated. No significant effect of Al sieve reinforcement in the polymer layer was observed on the low velocity impact response, except for the tests at 120 J.
