Carbon fiber is widely used in sports equipment. Carbon fiber tennis rackets have now become must-have equipment for champion players. The tennis racket made of carbon fiber can reach a maximum speed of nearly 250 kilometers per hour, but the high-performance aluminum alloy tennis racket can only reach about 200 kilometers per hour, and the speed has increased by more than 20%. The recently retired tennis player Federer won 20 Grand Slam championships with Pro staff, a carbon fiber tennis racket.
