摘要
以轻型高端公务机领世300增压舱共固化成型技术为研究背景,针对增压舱为固化炉整体成型的特点,借助DSC对T700G-12K碳纤维/环氧预浸料的固化温度和固化度进行了研究与分析,优化固化工艺参数。通过无损检测C扫描和力学测试进行验证。试验结果表明:增压舱固化工艺采用凝胶点温度80℃下处理240min,105℃下保温保压120min以及130℃下保温保压120min为本组试验的最优方案,产品缺陷少。
The pressurized cabin Co-curing technique of carbon fiber/epoxy prepreg for light high-end business jet AG300 was introduced and studied in this work common background.According to the characteristics of overall molding pressure cabin for curing furnace, with the aid of DSC to T700G-12K carbon fiber/epoxy presoak curing temperature and curing degree has carried on the research and analysis, optimization of curing process parameters validated through the nondestructive testing（NDT） C scan and mechanical testing.The results of the test indicate, The prepreg curing progress of the pressurized cabin using the gel point temperature of 80 ℃ for 240min under pressure, then cured at 105℃ for 120min, finally at 130℃ for 120min. It was the optimal scheme of the experimental group, fewer product defects.
