Carbon fiber is a fiber material composed of graphite with a carbon content higher than 90%. Prepared by reaction process. During the carbonization process, the carbon fiber is pre-stretched along the axial direction, so the graphite crystallites have a preferred orientation, endowing the carbon fiber

Carbon fiber reinforced plastic composite (CFRP) is a lightweight, strong material used to manufacture many products used in everyday life. It is a term used to describe fiber-reinforced composite materials with carbon fiber as the main structural component. It should be noted that the "P" in CFRP can also stand for "plastic" instead of "polymer".
