摘要: 实验探究单向碳纤维/环氧树脂预浸料在不同高温环境及不同方向的热响应行为。研究表明,单向碳纤维/环氧树脂预浸料在低于230 ℃的高温环境下,热响应温度、导热系数随热响应时间的增加而增大,其后趋于平稳;在高于230 ℃的高温环境下,热响应温度出现峰值,材料逐渐受损,热响应行为复杂。此外,研究得到单向碳纤维/环氧树脂预浸料在平面及厚度方向导热系数,发现平面方向导热系数始终大于厚度方向。

Abstract: The different directions of thermal response behavior of unidirectional carbon fiber/epoxy resin prepreg under different high temperature environment were experimentally investigated. The results showed that the thermal response temperature and thermal conductivity of unidirectional carbon fiber/epoxy resin prepreg increased with the increase of thermal response time and then tended to be stable at a temperature lower than 230 ℃. In high temperature environment above 230 ℃, the thermal response temperature peaks, the material is gradually damaged, and the thermal response behavior is complex. In addition, the thermal conductivity of unidirectional carbon fiber/epoxy resin prepreg in the direction of plane and thickness was obtained, and the thermal conductivity in the direction of plane was always greater than that in the direction of thickness.
