摘    要:分析了不同温度对组成Dyneema纤维增强复合材料的超高分子量聚乙烯纤维丝束拉伸强度的影响。并对UD75防弹复合材料在不同成型压力下的弹道吸能进行了研究。在对成型压力影响的研究中,对UD75复合材料的层间结合力、厚度和体密度进行了分析。结果表明,温度超过123 ℃后拉伸强度有大幅的下降,而成型压力为12.5 MPa时达到最大值。其研究结果对防弹复合材料的合理制备和优化设计提供了很好的参考依据。

关 键 词:纤维复合材料  超高分子量聚乙烯纤维  弹道吸能

Abstract:In this paper, the influence of temperature on the tensile strength of the ultra-high molecular weight polyethylene (UHMWPE) fiber strands which reinforce the UD75 composites is analyzed. The variation of ballistic absorption energy as well as the adhesive bonding force between layers, the thickness and density of laminates of UD75 composites with molding pressures is studied. The results show that the tensile strength of the UHMWPE fiber strands is greatly decreased when the temperature is higher than 123 ℃, and the ballistic absorption energy is up to the highest value when the molding pressure is about 12.5 MPa. The study results would be valuable for the proper preparation and optimum design of composite armors.
Keywords:fiber reinforced composite  ultra  high molecular weight polyethylene(UHMWPE) fiber  ballistic property
