Effect of Hygrothermal Environment on Shearing Property of Fiber Reinforced Resin-Based Composite Stiffened Panel
摘 要
对纤维增强树脂基复合材料加筋板进行湿热试验, 使其在70℃、水浴条件下达到吸湿平衡; 分别对普通加筋板和吸湿后加筋板进行了剪切试验, 研究了湿热环境对复合材料加筋板剪切性能的影响。结果表明: 试验过程中, 两种加筋板均未出现明显的屈曲现象, 其破坏形式主要表现为试样的四角破损、蒙皮开裂、变形等; 湿热环境对试样的剪切破坏载荷有着显著的影响, 吸湿后复合材料加筋板的破坏载荷下降了9.9%。
Abstract
Fiber reinforced resin-based composite stiffened panels were treated in a hygrothermal environment until they reached a moisture adsorption balance at 70 ℃ in a water bath. Then the effect of hygrothermal environment on shearing property of composite stiffened panels was studied in shear experiments for the stiffened panels before and after moisture adsorption. Results show that there is no obvious buckling in the test for two kinds of stiffened panels. The failure modes mainly contain damage of four corners, cleaving of skin and deformation of specimen and so on. The effect of hygrothermal environment on shearing failure load was so remarkable that it decreased by 9.9% after the composite stiffened panels absorbed moisture.
