摘要
尼龙热塑性复合材料的制备方法主要有热熔预浸料法和原位聚合法。相较于原位聚合法,热熔预浸料方法制备其复合材料成本高、效率低。针对尼龙热塑性复合材料高效、低成本制造的迫切需求,本文以纤维增强尼龙6复合材料为研究对象,综述了原位聚合制备尼龙6热塑性复合材料的工艺方法的研究进展,主要的工艺方法包括浇注、离心与旋转、拉挤以及液体模塑成型,着重论述了该种热塑性复合材料液体模塑成型工艺方法,并对其发展方向进行了简述。
The preparation methods of nlyon thermoplastic composite mainly include hot-melt prepreg method and in-situ polymerization method.Compared to the in-situ polymerization method,the hot-melt prepreg method always has higher cost and lower efficiency in producing composites.In reponse to the urgent demand for efficient and low-cost manufacturing of nlyon thermoplastic composite,this article takes fiber reinforced nylon 6 composites as the research object,summarizes the research progress of in-situ polymerization methods for preparing nylon 6 thermoplastic composites,including casting,centrifugation and rotation,pultrusion,and liquid molding.It focuses on the liquid molding process of this thermoplastic composite and briefly describes its development direction.
