基于飞行器减重对耐高温结构复合材料的应用背景,为了拓展国产T800碳纤维增强氰酸酯复合材料体系的应用,通过对国产T800碳纤维表面上浆剂的分析,开展适于国产T800碳纤维的氰酸酯树脂基体配方设计,研究国产T800碳纤维/氰酸酯复合材料的力学性能和耐热性能,分析树脂基体对复合材料界面性能的影响。结果表明:国产T800碳纤维表面上浆剂中含有环氧基团。配方优化后的氰酸酯树脂与国产T800碳纤维复合后,复合材料的室温-湿态力学性能保持率大于74.8%,200℃力学性能保持率大于57%,玻璃化转变温度为226℃,具有优异的热机械性能和界面性能。
In order to reduce the aircraft mass via high-temperature composite structures, and to extend the application of domestic T800 carbon fiber reinforced cyanate ester composites system, the sizing was analyzed, and the cyanate ester formulation was designed for the carbon fiber based on the sizing analysis. Meanwhile, the mechanical properties and heat resistance of the domestic T800 carbon fiber/cyanate ester composites were studied, and the effect of matrix on the composites interface was studied. The results indicate that the sizing of domestic T800 carbon fibers contain epoxy functional groups. With the formula optimized cyanate ester resin, the domestic T800 carbon fiber composite has greater mechanical property with the retention rate exceeding 74.8% at room-temperature with humidity, the retention of mechanical property is more than 57% at 200℃, and the glass transition temperature is 226℃. The composite exhibits excellent thermal mechanical and interfacial properties.
