▎ 摘　　要

The application of aramid fiber composites for ballistic purposes has increased in recent years. The addition of graphene in a polymeric matrix could boost the energy absorption and the ballistic protection of these composites. This study aims to investigate the performance of aramid fabric multi-laminar panels with high-density polyethylene (HDPE) films containing graphene nanoplatelets (GNP). Mechanical, dynamic-mechanical (DMA), ballistic impact, and split Hopkinson pressure testing were conducted. All composites obtained ballistic protection level III-A, with HDPE-0.5% GNP and HDPE-1% GNP obtaining the lowest subsequent deformations. HDPE-0.5% GNP showed the highest energy dissipation in DMA testing, corroborating the ballistic results.
