摘　　要：炭纤维单丝的压缩性能远低于其拉伸性能,而且与成熟的拉伸性能测试方法相比,炭纤维单丝压缩性能测试技术发展较缓慢。综述了多种炭纤维单丝压缩性能测试方法,比较了不同方法得到的炭纤维压缩强度以理解和分析不同方法的优缺点。同时从结构-性能关系的角度分析了多种炭纤维单丝压缩断裂机理。. Inferior axial compressive strength in comparison with tensile strength of carbon fibers has alwaysbeen a prompt in research of improving its compressive properties. However, comparing with well developedtechniques for measuring tensile properties of carbon fibers and composites, accurate measurement of compres-sive properties has not been without problem. Different test methods for determing the compressive strength ofsingle carbon fibers have been reviewed here. The testing results were compared and anaylzed to indicate theirapplicability. Possible compressive failure mechanisms in relate to microstructure of carbon fibers were dis-cussed.
