摘　　要：针对RTM成型工艺对基体树脂的特殊要求,结合MA型苯并噁嗪树脂耐烧蚀、高性能的特点,对制造高强度苯并噁嗪树脂基碳纤维复合材料进行了研究。系统考察了基体树脂体系的工艺性能、固化反应行为以及力学性能。结果表明:该树脂体系在95～115℃温度区间内至少有350min的低黏度(≤500mPa.s)时间作为工艺开放期,符合RTM成型工艺要求;树脂体系的玻璃化转变温度在223℃;RTM苯并噁嗪树脂基碳纤维复合材料的空隙含量仅为0.23%,树脂浇铸体和碳纤维复合材料的常规力学性能优异。MA型苯并噁嗪树脂完全可以采用RTM工艺成型高性能复合材料。Considering the special requirement of RTM molding process on matrix resin, and together with the abla- tive resistance and high performance of MA type benzoxazine resin, the preparation of benzoxazine resin based carbon fiber composites with high strength was studied. Then the processing property, curing reaction behavior and mechanical proper ties were systematically studied. The result showed that there were at least 350min long low viscosity time （≤500rnPa· s） treated as the process opening period for this resin system between 95～115℃, which was fit for the requirement of RTM molding process; the glass transition temperature of this resin system was 223℃ ; the void content of the benzoxazine resin based carbon fiber composites was 0. 23%, and the conventional mechanical properties of the resin casting body and the carbon fiber composites were excellent. MA type benzoxazine resin can be completely used by RTM molding process for composites with high performance.
