摘要

This investigates using graphene oxide (GO) as a nano-reinforcing filler to improve the impact resistance of polydiborosiloxane (PDBS) composite materials reinforced with Kevlar fibers. GO/PDBS/Kevlar composite materials were prepared by combining GO with PDBS and Kevlar. Results indicate that introducing GO and PDBS significantly increases the composite material’s energy absorption capacity. The protective performance of the material was evaluated using quasi-static penetration and low-speed drop impact tests. The maximum penetration force of the 5-layer C-PDBS/Kevlar composite material was 152 N, which is approximately 111% higher than pure Kevlar fabric (72 N). Low-speed drop impact tests demonstrated that adding GO effectively improves the material’s response under dynamic impact conditions. The peak force of a 10-layer C-PDBS/Kevlar composite material increased from 1620 N to 2294 N, a 41.6% increase. These results demonstrate that C-PDBS significantly promotes the energy dissipation mechanism of composite fabrics, enabling C-PDBS/Kevlar composites to exhibit excellent impact resistance.
