Experimental Investigation on Bullet Proof Materials: (FRP, UHMWPE, ARAMID, Al2O3 and SiC)

This project analyzes the hardness behavior of selected materials for bulletproof applications., namely fibrereinforced polymer (FRP), ultra-high-molecular-weight polyethylene (UHMWPE), aramid composite, alumina (Al₂O₃), and silicon carbide (SiC). These materials are commonly used in bullet proof materials and vehicle armor systems due to their distinct mechanical characteristics. Polymer-based armor layers such as FRP, UHMWPE, and aramid laminates are evaluated using the Shore D hardness test, which is suitable for assessing relatively softer composite materials. In contrast, ceramic materials like alumina and silicon carbide are examined using Rockwell and Brinell hardness tests to account for their extremely high stiffness and brittle nature. The study aims to measure and compare the hardness values of each material, analyze the influence of material composition and microstructure on hardness, and correlate these properties with reported ballistic performance parameters such as energy absorption and penetration resistance. Based on the results, suitable combinations of polymer and ceramic materials are identified for developing lightweight hybrid bullet-resistant panels, providing useful design data for future armor applications.
