【摘要】：以超高分子量聚乙烯(Ultra High Molecular Weight Polyethylene,UHMWPE)纤维、S-玻璃纤维、芳纶1414纤维和杂环芳纶纤维增强聚烯烃(Polyolefin,PO)和水性聚氨酯(Waterborne Polyurethane,WPU)树脂,采用热压工艺制备正交单向无纬(UD)结构复合材料装甲板;通过装甲板弹道极限速度测试,研究了纤维增强树脂基复合材料装甲板防弹性能的影响因素;通过体视显微镜观察装甲板侵彻破坏形貌,分析了纤维增强树脂基复合材料的破坏机制。结果表明:UHMWPE纤维增强PO树脂基复合材料的防弹性能与UHMWPE纤维的强度和模量呈正相关,但纤维模量对复合材料防弹性能的影响随着纤维模量的增大而逐渐变弱;在WPU树脂体系下,四种纤维的防弹性能由高到低依次是UHMWPE纤维、杂环芳纶纤维、芳纶1414纤维、S-玻璃纤维;纤维增强树脂基复合材料装甲板中纤维破坏方式有迎弹面纤维被剪切冲塞、中部被纤维拉伸变形后剪切、背弹面纤维被拉伸断裂,中部纤维拉伸变形是消耗子弹动能的主要方式。
[Abstract]:Ultrahigh molecular weight polyethylene (UHMWPE) was prepared by using Ultra High Molecular Weight polyethylene (UHMWPE) fiber. Aramid 1414 fiber and heterocyclic aramid fiber reinforced polyolefin polyolefinopol) and waterborne Polyurethane. WPU-based resin was used to prepare orthogonal unidirectional weft free UD composite armor plate by hot pressing process. By measuring the ballistic limit velocity of the armor plate, the factors influencing the bulletproof performance of the fiber reinforced resin matrix composite armor plate were studied. The penetration and destruction morphology of armor plate was observed by stereoscopic microscope. The failure mechanism of fiber reinforced resin matrix composites was analyzed. The results showed that the bulletproof properties of w / UHMWPE fiber reinforced PO resin matrix composites were positively correlated with the strength and modulus of UHMWPE fibers. However, the effect of fiber modulus on the bulletproof property of composites becomes weaker with the increase of fiber modulus. In the WPU resin system, the four fibers' bulletproof properties from high to low are UHMWPE fiber, heterocyclic aramid fiber, aramid 1414 fiber and S- glass fiber. The fiber failure mode of fiber reinforced resin matrix composite armor plate includes shearing and sluicing of facing surface fiber, shearing of middle part of fiber stretch deformation, tensile fracture of back elastic surface fiber. The tensile deformation of the central fiber is the main way to consume the kinetic energy of the bullet.
