| Abstract Scope |
This study presents the design, processing, and the advanced characterization of ballistic protection hard plates manufactured via hot pressing of two different types of UHMWPE-based prepreg composites, with selective inclusion of a Ti-6Al-4V alloy layer. The research integrates a suite of in-situ and post-impact techniques to assess structural evolution and performance under impact. Characterization involved FTIR, DSC, and TGA for chemical and thermal profiling, SEM and metallography for microstructural evaluation, hardness and fiber tensile testing. Ballistic performance was assessed using high-speed imaging, V50 impact velocity testing, and 3D laser scanning equipment to quantify back-face deformation profile. Results show that substituting up to 30% of the prepreg with a 1 mm Ti-alloy layer-maintained protection standards and the areal density. This combined approach highlights how materials characterization—not only post-process but during mechanical performance—can directly inform optimized processing routes for armor-grade composite systems. |
