Abstract:
通过差示扫描量热（DSC）法研究了9518氰酸酯的固化反应，制定了9518氰酸酯的固化工艺；通过动态热机械分析（DMA）测试、力学性能测试、金相显微镜和SEM等方法研究了T800碳纤维/9518氰酸酯复合材料的受热行为、力学性能、纤维微观形貌和界面特性。结果表明：9518氰酸酯的固化反应只有一个固化反应放热峰，其比较合理的固化工艺为130℃/0.5 h+160℃/0.5 h（加压合模）+200℃/2 h+230℃/2 h。T800碳纤维/9518氰酸酯复合材料的玻璃化转变温度为255℃，其各项力学性能比T700碳纤维/9518氰酸酯复合材料提高均大于10%，室温-湿态力学性能保持率大于83%，200℃的力学性能保持率大于60%。T800碳纤维不规则的截面和表面沿长度方向的沟槽有利于树脂与纤维间形成良好的结合界面。 Studies on characteristics of 9518 cyanate ester curing reaction were performed via differential scanning calorimetry (DSC) analysis, the curing process of stated resin was determined; Thermal stability, mechanical properties, fiber morphology and interface properties of T800 carbon fiber/9518 cyanate ester composites were analyzed via dynamic mechanical analysis (DMA) testing, mechanical property testing, metallography and SEM, respectively. The results show that, the curing reaction of 9518 cyanate ester has only one reaction exothermic peak, one of the reasonable curing processes for the resin is 130℃/0.5 h+160℃/0.5 h(pressure-enforcement and mold-closing)+200℃/2 h+230℃/2 h. The glass transition temperature of T800 carbon fiber/9518 cyanate ester composites is 255℃. In general, mechanical properties of T800 carbon/9518 cyanate ester composites at room temperature are 10% higher than that of T700 carbon fiber/9518 cyanate ester composites, wet mechanical properties conservation rate of stated composites at room temperature are more than 83%, and withhold more than 60% at 200℃.Cross-section of T800 carbon fiber appeares abnormal round shape and along the fiber has ditches on the surface, contributing a fine interface between T800 carbon fiber and 9518 cyanate ester resin. 陕西省自然科学基金（2015JM3080）；安徽省重大科技专项子题（17030701019）；西安市碑林区科技计划项目（GX1712）
