摘要: 本研究对芳纶纤维与超高分子量聚乙烯(Ultra-High Molecular Weight Polyethylene,UHMWPE)纤维混杂复合材料梯度设计的防弹性能影响进行了探究。设计5种UHMWPE含量梯度方案(层数分别为0,10,20,30,40层),总面密度均严格控制在(6±0.05) kg/m2以下。通过弹道测试(分别以芳纶和UHMWPE作为弹击面),系统分析了纤维含量及铺层顺序对层合板弹道极限速度V50和弹道性能指数(Ballistic Performance Index,BPI)的影响规律,并基于试验数据建立了纤维含量与防弹性能的三次项非线性回归定量关系模型(R2>99%),为混杂纤维复合材料的梯度设计与防弹装备开发提供了科学依据。

Abstract: This study investigated the influence of gradient design on the ballistic performance of aramid fiber and ultra-high molecular weight polyethylene (UHMWPE) fiber hybrid composites. Five gradient schemes with varying UHMWPE content (corresponding to 0, 10, 20, 30 and 40 layers) were designed, with the total areal density strictly controlled below (6±0.05) kg/m2 for all configurations. Ballistic tests were conducted, utilizing both aramid and UHMWPE as the impact faces, to systematically analyze the effects of fiber content and stacking sequence on the ballistic limit velocity V50 and ballistic performance index (BPI) of the laminates. Based on the experimental data, a cubic nonlinear regression quantitative relationship model (R2>99%) between fiber content and ballistic performance is established,which provides a scientific basis for the gradient design of hybrid fiber composites and the development of ballistic protection equipment.
