树脂性能及制备工艺对超高分子量聚乙烯纤维/水性聚氨酯复合材料抗弹性能影响
Effect of resin properties and preparation processes on the anti-elastic properties of UHMWPE fiber/waterborne polyurethane composites
摘要
Abstract
Using waterborne polyurethane as matrix and ultra-high molecular weight polyethylene(UHMWPE)fiber as reinforcement,unidirectional and orthogonal composite soft bulletproof layer was prepared.Based on ballistic penetration test and non-destructive testing,the effects of resin modulus,resin content,fiber development degree and other technological parameters on the elastic resistance of the soft bulletproof layer of advanced composites were studied.The results show that the UHMWPE composites prepared with low resin content,low modulus resin and proper placement rate present better ballistic penetration performance.The low resin content increases the fiber pro-portion,resulting in more fiber bearing capacity per unit surface density.The low modulus resin can reduce the stiff-ness of the composite,allowing more fibers to pull out and break in the affected area.Although the faster arrange-ment rate can improve the production efficiency,it will generate more tension and damage the fiber during the pro-duction process.By analyzing the influence of various factors on the ballistic properties of composites,the technolog-ical parameters of ballistic composites can be better designed and the soft bulletproof layer of advanced composites can be prepared.关键词
