The application of carbon nanofibers in the automotive field is as follows:

Lightweight: Because of its low density and high strength characteristics, nanocarbon fiber composite materials are used in automobile manufacturing to achieve lightweight, thereby improving the energy saving, acceleration and braking performance of automobiles. According to research, every 100kg reduction in vehicle mass can save fuel 0.003~0.005L/km, reduce CO2 emissions 0.08~0.11g/km, improve acceleration performance by 8%~10%, and shorten the braking distance by 2~7m

Improved stability: The tensile strength of nanocarbon fiber composite materials is high, and its collision absorption energy is 6-7 times that of steel and 3-4 times that of aluminum, which helps to improve the stability of vehicles

Durability: Due to the chemical stability of carbon fiber composite materials, excellent weather resistance and aging resistance, generally 2-3 times that of steel, so when used to produce functional parts, its fatigue strength is also much higher than that of steel

Enhanced comfort: Nano-carbon fiber composite materials have higher vibration damping, which can reduce vehicle noise, vibration and acoustic roughness (NVH) performance, and increase the comfort of driving

Design flexibility: Nanocarbon fiber composite materials have high integration and free modeling, which can reduce the number of parts, save production input, and enhance the sense of design

Wide range of applications: nano-carbon fiber composite materials in automotive applications include body, interior and exterior decoration, chassis system, power system and so on

Wheels and brake discs: Wheels made with nanocarbon fiber composites significantly reduce weight and wheel inertia, allowing vehicles to start, brake and steer faster. Carbon fiber brake disc can withstand high temperature and improve braking performance

Environmental protection and energy saving: The application of nanocarbon fiber materials helps to save energy and reduce emissions of automobiles, which meets the needs of global climate change response and environmental protection and energy saving

Cost and process: Although nanocarbon fiber composites have many advantages, their cost is high and the process is complex, so it is important to develop new technologies and new processes to reduce costs and improve production efficiency
