【摘要】 本文选取航天器复合材料结构件常用基体环氧树脂,利用拉伸蠕变试验方法对其蠕变性能改善方法进行研究。在理论分析基础上采取时效处理、温度循环处理和多壁碳纳米管处理三种方法对环氧树脂进行处理,通过对比处理前后环氧树脂的蠕变应变增量和归一化蠕变应变—时间曲线,得出了三种处理方法对环氧树脂蠕变性能的影响。更多还原

【Abstract】 This paper studied methods of improving creep resistance of exopy resin,which was the common resin for composite structures of spacecrafts,with tensile creep tests. Based on theoretic analysis,three methods time-treatment,temperature cycle and multiwalled carbon nanotubes were chosen,then the effect of these methods were got through comparing the creep strain increment and normalized creep strain-time curves of the resin before and after the treatment.更多还原
