Abstract: The multi-walled carbon nanotubes/resin epoxy composite was prepared and the composition and operating conditions were obtained. The transmission electron microscopy (TEM) was used to observe carbon nanotubes and the carbon nanotubes/resin epoxy composite. Moreover, the mechanical properties of the carbon nanotubes/resin epoxy composite were measured by the experiments of tension and compression. The results show that carbon nanotubes could obviously improve the mechanical properties of the resin epoxy bulk material.
