Abstract Scope |
Carbon fiber reinforced composites achieve superior mechanical properties but lack of toughness, extreme thermal resistance, and damping capabilities. For industrial damping applications, conventional damping materials are used for their excellent ability to attenuate vibrations but these materials exhibit poor mechanical properties. These limitations can be eliminated by creating structural multifunctional composites that have high specific strength and stiffness with a broad service temperature range but also offer other functionalities such as tailorable electrical conductivity and high damping capabilities. Graphene oxide films have shown promising results in simultaneous high stiffness and high damping films. In this study, the effect of adding carbon fibers to a graphene oxide matrix is investigated as a potential multifunctional film which improve upon the mechanical properties seen in pure graphene oxide films. Through the process of vacuum filtration, micron-thick GO films are fabricated and impregnated with electrospun polyacrylonitrile fibers. With proper heat treatment, the fibers are then carbonized to create carbon-carbon composites that display exceptional properties including interesting damping and electrical properties. |
