纳米ZrO_(2)改性玄武岩纤维层压板抗侵彻性能研究

Study on anti-penetration performance of basalt fiber laminates modified by ZrO_(2) nanoparticles

为了探究纳米二氧化锆(ZrO_(2))粒子对玄武岩纤维/乙烯基酯树脂层压板力学性能和抗侵彻性能的影响,采用热压法制备纳米ZrO_(2)改性基体复合材料,开展准静态拉伸测试与弹道试验,并对试件的弹道损伤形貌进行宏观/微观分析。研究结果表明:纳米ZrO_(2)可以提升玄武岩纤维/乙烯基酯树脂层压板的拉伸强度和模量,但会导致拉伸断裂应变下降并影响其能量吸收。弹道试验结果表明,少量添加纳米ZrO_(2)粒子(0.5 wt%)的层压板抗侵彻性能有所提升,弹道极限提高6.01%,而粒子含量更高的试件抗侵彻性能出现下降。改性引起的界面黏附性增强会限制变形、脱黏等吸能行为,从而导致抗侵彻性能下降。研究结果可为基于玄武岩纤维层压板的硬质防护装备开发提供参考。

In order to investigate the influence of zirconium dioxide(ZrO_(2))nanoparticles on the mechanical properties and anti-penetration performance of basalt fiber/vinyl ester resin laminates,the ZrO_(2) nanoparticles modified matrix composites were prepared by the hot pressing method.The quasi-static tensile test and ballistic test were carried out,and the ballistic damage morphologies of the specimens were analyzed at the macro/micro level.The results show that ZrO_(2) nanoparticles can improve the tensile strength and modulus of the basalt fiber/vinyl ester resin laminates,but it will lead to the decrease of tensile fracture strain and affect its energy absorption.The ballistic test results show that the anti-penetration performance of the laminates with a small amount of ZrO_(2) nanoparticles(0.5 wt%)is improved,and the ballistic limit increases by 6.01%,while the anti-penetration performance of the specimens with higher particle content decreases.The enhanced interface adhesion caused by modification will limit the energy absorption behaviors such as deformation and debonding,thus lead to the decrease of anti-penetration performance.The research results can provide reference for the development of hard protective equipment based on basalt fiber laminates.
