Study on Three-Dimensional Braided Irregular Carbon Fiber Reinforced Preform

新一代武器装备的快速发展和战略技术指标的不断提高,迫切需要在高性能纤维增强复合材料生产工艺和制备技术方面加速攻关突破。三维编织碳纤维预制体由于其可设计性强,特殊的耐腐蚀性能,耐疲劳性好等优点,在各种武器装备的轻量化、小型化和高性能化上起到了至关重要的作用。以三维编织异型碳纤维预制体为对象,研究数字模拟三维编织动程,分析分散减纱工艺及不等层设计工艺原理,为三维编织异型碳纤维预制体的净近成型的实现作理论参考。

With the rapid development of the new generation of weapons and equipment for strategic and technical indicators,it is urgent to speed up the breakthrough high-performance fiber reinforced composites for us in the production technology and preparation technology.The three-dimensional braided carbon fiber-reinforced preform has the advantages of design,special corrosion and fatigue resistance that played a vital role in lightweight,miniaturization and high performance for all kinds of weapons and equipment.Taking the three-dimension braided irregularcarbon fiber reinforced preform as the object,the digital simulation of three-dimension braided motion was studied,and the dispersed yarn reduction process and unequal row de-sign technology were analyzed,so as to provide a theoretical reference for the realization of the overall mold-ing of three-dimension braided irregular carbon fiber reinforced preform.
