摘　　要：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。Three kinds of different COPNA resins have been obtained using different materials to react with across-linking reagents in acid environment. Three different matrix composites have been made by molding with carbon fibers using three different resins as matrix. The COPNA resins' adhesive properties including softening-point .residual carbon content,and β resin content and composites' heat-proof property have been tested. Experiment data showed that COPNA resins can meet the requirements of binders used in carbon field,and have good adhesion. The composites used COPNA resins as matrix showed well property than conventional bakelites and epoxy resins. This indirectly identified that COPNA resins have good adhesive property with carbon fibers. It offers a good direction for COPNA resins' application.
