摘要
Abstract
A one-component waterborne epoxy resin(WER)suitable for ultra-high molecular weight polyethy-lene(UHMWPE)fiber non-woven fabric was synthesized.Unidirectional(UD)orthogonal non-woven fabric and composite panels were prepared using a winding-composite-hot pressing process.The resin's resistance to high/low temperatures and aging properties were investigated,along with the storage stability of WER-based UHMWPE non-woven fabrics under accelerated aging tests.The mechanical performance of composite panels at different tempera-tures and the ballistic limit V50 value were also studied.The results indicate that the epoxy resin exhibits favorable high temperature resistance,the tensile shear strength of WRE resin is maintained at a high level at 80℃,and at a low temperature of-40℃,the performance does not decrease compared with the normal temperature state.Through accelerated aging simulations and calculations using the Arrhenius equation,the epoxy adhesive demonstrates per-formance attenuation after approximately 279 days in a 23℃environment.The WER-based non-woven fabric dis-plays excellent storage stability,maintaining stable performance for about 117 days under 23℃conditions.Evalua-ted through V50 ballistic testing,the ballistic performance of WER matrix composites was almost unchanged after 400 h with testing under double 85 conditions.关键词
