研究了多壁碳纳米管/环氧树脂复合材料在拉伸和压缩两种情况下的力学行为。发现压缩模量高于拉伸模量，表明在压缩时向复合材料中的纳米管的载荷传递高得多。此外，还发现，拉曼峰的位置，表明在负载下的碳键中的应变，位移显着压缩下，但不是在拉伸。有人建议，在负载转移到多壁纳米管，只有外层的张力，而所有的层在压缩响应。(C)1998年美国物理学会。[S0003-6951（98）00252-6]。
The mechanical behavior of multiwalled carbon nanotube/epoxy composites was studied in both tension and compression. It was found that the compression modulus is higher than the tensile modulus, indicating that load transfer to the nanotubes in the composite is much higher in compression. In addition, it was found that the Raman peak position, indicating the strain in the carbon bonds under loading, shifts significantly under compression but not in tension. It is proposed that during load transfer to multiwalled nanotubes, only the outer layers are stressed in tension whereas all the layers respond in compression. (C) 1998 American Institute of Physics.
