ABSTRACT
The research and development of carbon fiber-reinforced polymer composites started in the 1960s. Carbon fibers consist of tightly packed graphene sheets that are aligned parallel to the fiber axis. The principal advantages of using carbon fibers include their high modulus (up to 400 GPa), high strength (up to 3.4 GPa), low density (specific gravity around 2.0), and low cost compared to many other reinforcement materials.1
