Prof. Dr. Laith Waddah Ismail/ University of Technology/ Materials Engineering Department.

After the discussion committee made their remarks and observations on the thesis, which were divided between explanation, correction and the student’s defense of her message and the discussion ended, the committee decided to evaluate the thesis, and decided to grant the student a master’s degree with a Pass grade

 Abstract

Researchers investigated new body armor technologies in response to the development of new weaponry. This research aims to create a hybrid composite and test it experimentally and theoretically under ballistic impact. Body armor is designed with multiple layers. The first design consisted of rubber/ceramic/ (Al2O3) rubber/20 layers of UHMWPE reinforced epoxy/rubber. Where rubber and ceramics represent the first line of protection against lead, followed by the intermediate compound. Then rubber was used for the back layer. The second design consisted of ceramic (Al2O3)/10 layers of UHMWPE reinforced epoxy/steel/ceramic (Al2O3)/10 layers of UHMWPE reinforced epoxy/steel. Where the area of both armor was 900 cm2 and an AK-47 bullet was fired at a distance of 15 m at a speed of 730 m/s, and another 9 mm pistol bullet was fired at a distance of 5 meters and a speed of 310 m/s against both armors. Where the results of the ballistic examination showed that the first and second armor were punctured and penetrated by an AK-47 bullet, while the second armor stopped the 9 mm pistol bullet without a hole, ANSYS Autodyn R21 was used to simulate the ballistic effect..
