Book excerpt: Report developed under STTR contract for topic AF08-T028. Polyacrylonitrile/carbon nanotube composite fibers are processed and used to produce high strength and high modulus carbon fibers. In order to produce composite fibers, several spinning technologies have been used, which are called gel spinning and bi-component spinning. Carbonization process of the composite fiber was optimized to obtain high strength and high modulus carbon fiber. The resulting carbon fibers possessed average tensile strength up to 5 gigapascal (GPa) and average tensile modulus up to 410 GPa. The highest strength and modulus to date are 7.1 GPa and 476 GPa, respectively. These nanotailored carbon fibers will have superior mechanical properties as well as better electrical and thermal conductivity as compared to the conventional carbon fibers, which should result in significant weight savings and functionality in various aerospace composite systems.
