摘　　要：本文采用苯并噁嗪对氨酚醛树脂共混改性,并通过模压与高硅氧纤维制备成复合材料。进行了力学性能、烧蚀性能和热学性能测试。结果表明:与氨酚醛/高硅氧体系对比,加入苯并噁嗪树脂体系的拉伸强度降低了31.3%,这可能是由于苯并噁嗪分子结构柔韧性较差导致的,而玻璃化转变温度和烧蚀性能有大幅提高,其中玻璃化转变温度提高了15.7%,线烧蚀率降低了59%,质量烧蚀率降低了24.7%。The composite was prepared by blending modification of benzoxazine with ammonia phenol formaldehyde resin and molding with high silica fiber.And the mechanical properties,ablative property and thermal properties were tested.The results showed that the tensile strength of benzoxazine resin system decreased by 31.3%compared with the aminophenol formaldehyde/high silica system,which may be due to the poor flexibility of benzoxazine molecular structure.However,the glass transition temperature and ablation performance have been greatly improved,including 15.7%increase in glass transition temperature,59%reduced in liner ablation rate and 24.7%reduction in mass ablation rate.
