MATERIALS SELECTION FOR CARBON NANOTUBE COMPOSITES IN POWER TRANSMISSION

Nowadays designers and producers implement non-metallic gears in power transmissions because of their better mechanical properties, like high elastic modulus, tensile strength and high wear resistance. In order to examine these properties we need to get familiarized with the most common materials used to make composites, like POM, PEEK, PA 6, PA 6/6, UHMWPE and one of newest materials in this area ? carbon nanotubes (CNTs). This paper describes how to select the best materials in order to create the composite we need for the necessary applications. The article also gives information about the polymers and a comparison between them and CNTs.
