温热环境对复合材料结构承载能力影响试验研究

Experimental Research on the Influence of Hygrothermal Environment on Compressive Carrying Capacity of Composite Stiffened Plates

针对复合材料结构设计时需考虑湿热环境的影响这一问题,分别进行了室温和湿热环境下的标准试样级许用值试验及加筋壁板典型细节结构轴压和剪切载荷试验,给出了许用值试验的环境补偿因子及加筋壁板的破坏载荷。试验结果表明,标准试样级试验得到的设计值较为保守。因此,在进行复合材料结构设计时还应综合考虑典型细节试验的结果。

The influence of hygrothermal environment on composite plates must be considered when design composite structure. In this paper, some standard sample tests, typical detail tests and shear load tests were carried out in the indoor temperature and hygrothermal environment, Allowable value environment compensation factor and failure load of stiffened plate were given. The results indicated that the design value obtained from standard sample tests were conservation. Thus the typical detail test results must be considered as well when designing composite structure.
