摘要： 文章通过对不同曲率半径的复合材料曲板进行稳定性试验，研究曲率半径变化对试验件屈曲载荷及屈曲模态的影响。研究表明，当试验件的曲率半径减小25%时，屈曲载荷提高了26%；曲率半径对屈曲模态的影响较小。

Abstract: This artical by the stability experiment on the composite curved plates of different radius, studying the influ?ence of different radius on the buckling loads and the buckling modes of the test pieces. The following results are ob?tained:the radius of the test pieces reducing 25%, the buckling load increases 26%;while the influence of radius on the buckling mode is very small.
