摘要: 本文以复合材料加筋壁板长桁截止端为研究对象,介绍了复合材料加筋壁板长桁截止端试验件的构型、试验方案、试验过程和试验结果,对其在湿热环境和常温环境下的力学性能进行了对比分析。结果表明,试验件刚度受湿热环境影响较小,试验件强度受湿热环境影响较大,即湿热环境下试验件强度明显小于常温环境下试验件强度,因此在结构设计时需要考虑湿热环境对复合材料结构力学性能的影响。

Abstract: This paper takes the runout of the composite reinforced stiffened panel as the object, and analyzes its mechanical properties in hydrothermal and normal environment through experiments. This paper describes the configuration, test plan, test process and test results. The results show that the hydrothermal environment has little effect on the stiffness of the structure, but has a certain influence on the strength. Therefore, the influence of the hydrothermal environment should be considered in the structural design.

Key words: composite materials, stiffened panels, runout, mechanical properties
