摘要: 文中对Dyneema UD66超高分子量聚乙烯纤维复合材料在不同成型压力、面密度和弹击速度下的弹道吸能进行了研究.因此在优化成型压力的研究中,对UD66复合材料靶板的层间结合力、厚度与体密度做了研究.结果表明,成型压力在2.5MPa左右时吸能达到最大值.在UD66复合材料靶板弹道吸能规律的研究中,对UD66靶板弹击后变形和破坏做了分析.其研究结果对今后防弹复合材料的优化设计有很好的参考价值.

Abstract: The variation of the ballistic absorption energy of Dyneema UD66 fiber composite,an ultra-high molecular polyethylene fiber reinforced composite,with molding pressure,areal density and projectile velocity is studied.The molding pressure of UD66 fiber composite has direct effects on the ballistic absorption energy,so the relation of molding pressure with the adhesive bonding force between layers,the thickness of the laminates and density is investigated during the optimum of the molding parameters.The result shows that when the molding pressure is about 2.5MPa,the ballistic absorption energy is up to the highest value.For the study of the principles of the ballistic absorption energy,the deformation and fracture area of the UD66 fiber composite armors after ballistic impact are analyzed.The study results would be valuable for the optimum design.
