Abstract

The test team performed a comprehensive investigation into the ballistic performance of composite armor materials, with a focus on aramid and S-2 fiberglass fiber composites. The study aims to update existing testing standards, particularly MIL-STD-662F, by providing detailed insights into the effects of weave matrices and secondary impacts on ballistic strength. The research employs a rigorous experimental approach utilizing the Three-Phased Optimal Design algorithm to determine V50 values for various composite materials. Special attention is given to understanding the influence of fabric weave matrices on ballistic performance of primary and secondary impacts. Testing methodologies categorized secondary shots into close and medium shot-to-shot proximities to assess the effects of secondary impacts on V50. Results showed significant variations in ballistic performance based on matrix material, shot-to-shot distance, and delamination effects. The findings underscore the importance of matrix material selection, testing methodologies, and ongoing research to optimize composite armor design for enhanced ballistic resistance in modern conflict scenarios.
