Resumen
In this study, the high velocity impact response of a lightweight composite structure comprising an aramid honeycomb core sandwiched between two aluminum sheets was investigated against conical and hemispherical projectiles. It used a pneumatic gas gun and Abaqus software to conduct experimental and numerical research, respectively, focusing on damage behavior and failure modes, with a systematic parametric and optimization study for optimum ballistic performance. Results revealed that varying the rear sheet thickness and cell length had the most significant effects. Overall, the multifaceted approach advances the development and optimization of advanced composites for impact-resistant technologies where weight savings are critical.
