Carbon fiber is mainly used to reinforce composite materials, particularly in polymers. Another use exploits the contribution of a great aesthetic value to various consumer products. Among its features stand out the high mechanical strength, low density, the capacity of thermal insulation, resistance to temperature changes and to the effect of chemical agents, good fire retardant properties. However the material often has a strong anisotropy, ie its mechanical characteristics have a privileged direction. Carbon cloth, carbon fiber or carbon fabric all are names used to describe the reinforcement of carbon fiber implemented in many of today’s advanced composites.
