This chapter reviews the mechanical strength and weakness of carbon materials. It focuses on “real,” disordered, or nanostructured carbon materials, the defects being the secondary bonds that can be detected viscomechanically, hence offering a method to conduct comparative investigations not available from other analysis techniques and discusses the effect of nanopatterning on carbon materials. The important topic concerning the nanomanufacturing of carbon devices is the development of an adequate patterning technology. Carbon’s ability to hybridize as single or double bonds is responsible for the formation of only diamond and graphite; a host of other elemental carbon materials with wide-ranging properties appear in nature or have been synthesized for commercial applications. The idea behind this technology is that hydrocarbon layers often built up on material surfaces when subjected to electron or ion beam irradiation in the presence of oil vapors from the vacuum system.
