Investigation and analysis of the dynamic behavior of composite materials and their failure resistance are essential. The main aim of this study is to investigate the improvement of impact properties of incorporated glass fiber reinforced polymer (GFRP) composite specimens with various loading of nanoclay and nanosilica in a corrosive environment. After fabrication of samples by hand layup method, all of them were immersed in 5 wt. % of sulfuric acid solution for 0, 1 and 3 months. As the immersion time increased, the specimens containing nanosilica absorbed more water than the other samples. The force-displacement, force-time and energy-time diagrams showed the superiority of filled composites with nanoparticles over the pure sample in all immersion periods. Low-velocity impact (LVI) test results of specimens containing nanoclay showed a better behavior and with the addition of 5 wt. % of nanoclay, the impact force increased by 15.72% and the displacement decreased by 5.26%. Also, in these samples, the energy absorption rate decreased by 17.15%, which was associated with a reduction in the damage rate. After immersion of specimens in different times, specimens containing 5 wt. % of nanoclay had better strength than other samples and maintained their superior properties. The obtained results illustrated that the addition of 1 and 3 wt. % of nanosilica had no specific effect on the improvement of impact properties. Finally, incorporated GPRP composites with 3 wt. % of nanoparticles were simulated using LS-DYNA software and the experimental and numerical results were compared to investigate their accordance.

对复合材料的动态行为及其抗破坏性进行调查和分析是必不可少的。本研究的主要目的是研究在腐蚀环境中加入不同负载​​的纳米粘土和纳米二氧化硅的玻璃纤维增​​强聚合物 (GFRP) 复合材料试样的冲击性能的改善。通过手糊法制作样品后，将它们全部浸入 5 wt. 0、1 和 3 个月的硫酸溶液百分比。随着浸泡时间的增加，含有纳米二氧化硅的样品比其他样品吸收更多的水。力-位移、力-时间和能量-时间图表明，在所有浸渍阶段，填充纳米颗粒的复合材料均优于纯样品。含有纳米粘土的样品的低速冲击 (LVI) 测试结果显示出更好的行为，并且添加了 5 wt. %纳米粘土，冲击力增加15.72%，位移减少5.26%。此外，在这些样品中，能量吸收率降低了 17.15%，这与损坏率的降低有关。试样浸泡不同时间后，试样中含有 5 wt. % 的纳米粘土具有比其他样品更好的强度并保持其优越的性能。所得结果表明，添加 1 和 3 重量％。纳米二氧化硅的百分比对冲击性能的改进没有具体影响。最后，加入了 3 wt. 的 GPRP 复合材料。
