Reducing vehicle fuel consumption is one of the concerns of the contemporary automotive industry, and lightweight body technology can achieve the goal of energy conservation and emission reduction to a certain extent.

Carbon fiber reinforced plastic is a type of engineering material with high mechanical properties made by using carbon fiber as a modified reinforcement material and a plastic matrix through certain methods. The toughness and tensile strength of carbon fiber reinforced materials are higher than that of aluminum alloy, second only to steel, and the density is only 1/6-1/7 of steel. For ordinary family cars, wings made of carbon fiber reinforced plastic lose 50% weight compared to steel wings, Effectively reduces vehicle fuel consumption.

At the same time, carbon fiber reinforced plastic has high tensile and impact strength. After being impacted, the vehicle body can absorb a large amount of energy, and the energy transmitted to the driver's cabin is minimal, which can fully reduce the harm to drivers and passengers. In addition, carbon fiber reinforced plastic automotive fenders also have advantages such as good coordination, low requirements for assembly accuracy, good high-temperature stability, and easy modular design to achieve assembly integration. Therefore, they have become the most widely used material type and have broad application prospects.
