以三种不同的油浆为原料,在酸性催化剂存在下,与对苯二甲醇反应,得到三种COPNA树脂。以COPNA树脂、酚醛、环氧树脂为基体,与碳纤维复合,通过模压成型,得到三种不同基体的复合材料。考察了COPNA树脂的软化点、残炭、β树脂含量等粘结性参数以及树脂/炭纤维复合材料的耐热性能。经过分析认为,得到的COPNA树脂可以达到工业粘合剂的要求,具有很好的粘绪作用;以COPNA树脂为基体的炭纤维复合材料,表现出很好的耐热性,这为COPNA树脂的应用提供了一个很好的方向。
Using three different oil slurries as raw materials, three kinds of COPNA resins were obtained by reacting with p-xylylene glycol in the presence of an acidic catalyst. With COPNA resin, phenolic, epoxy resin as the matrix, and carbon fiber composite, by molding, get three different matrix composite material. The bonding parameters of COPNA resin, such as softening point, residual carbon and β-resin content, and the heat resistance of resin / carbon fiber composites were investigated. After analysis, the obtained COPNA resin can meet the requirements of industrial adhesives and has good sticky effect; the COPNA resin-based carbon fiber composite material shows good heat resistance, which is a good choice for COPNA resin Application provides a good direction.
