The middle of the material is an aluminum plate with a honeycomb structure

The outer layers on both sides are carbon fiber reinforced plastic (CFRP). The F1 racing chassis made of this material is only heavy, but its strength is much higher than that of ordinary steel structures. Therefore, carbon fiber materials are widely used in the manufacture of many parts such as suspensions, steering wheels, and brake discs of racing cars. In addition, the extensive use of light alloys has enabled the "massive heavyweights" such as the engine and transmission of the racing car to be "slim down". For example, the transmission housing of the Ferrari racing car is made of titanium alloy.
