摘要
设计和制备了高温尼龙(PPA)熔融浸渍碳纤维装置,用熔融浸渍法制备长碳纤维增强PPA复合材料(LFPPA)。主要研究了长碳纤维增强PPA的浸渍工艺条件与材料性能之间的关系。分别研究了不同熔体质量流动速率(MFR)、浸渍槽浸渍温度、浸渍时间等浸渍工艺对长碳纤维增强PPA性能的影响。提高浸渍温度与延长浸渍时间都可以提升浸渍效果,增强复合材料的拉伸性能。
Long carbon fiber reinforced polyphthalamide(LFPPA) was prepared by self-designed PPA melt impregnation device.This paper mainly studied the effect of various impregnation processes such as MFR,impregnating temperature and impregnating time on the properties of preparing long carbon fiber reinforced polyphthalamide(LFPPA).The result showed that raising temperature,prolonging impregnation time had clear effect to improve the impregnation effect and tensile properties of the composite.
