graphite is known as the black lead commonly used in pencils. However, there are many grades of graphite with a dazzling array of applications.
Carbon fiber is a graphite fiber that is extremely lightweight and strong. It is made by drawing the fiber into long strands, heating to a high temperature, and carbonizing to expel the non-carbon atoms. The surface is then treated and the fiber is ready to be used in various products....
