The applications of aramid in the automotive industry mainly include the following aspects: 1. Reinforcement of Automotive Tires: Aramid fibers are used in the production of tire cords. Due to their high strength, high modulus and excellent heat resistance, they can enhance the strength and durability of tires, improve the load-bearing capacity and puncture resistance of tires, and help to maintain the stability of tire shape during high-speed driving, thereby improving driving safety. 2. Production of Automotive Brake Systems: In brake pads and brake linings, aramid fibers are often added. They can increase the friction coefficient of brake materials, make the braking effect more reliable, and at the same time have good wear resistance and heat resistance, which can effectively reduce the occurrence of brake fade and improve the overall performance and service life of the brake system. 3. Automotive Body and Structural Parts: Aramid fibers can be used to make composite materials for automotive body parts and structural components, such as car doors, hoods, and chassis parts. The use of aramid composites can significantly reduce the weight of the vehicle body, improve fuel efficiency, and at the same time maintain high strength and rigidity, enhancing the collision resistance and safety of the vehicle. 4. Automotive Interior Decoration: In the automotive interior, aramid fabrics are used for seat covers, door panels and other parts. They not only have good wear resistance and stain resistance, but also have excellent flame retardancy, which can improve the fire safety of the vehicle interior and provide passengers with a more comfortable and safe riding environment. 5. Automotive Electrical Systems: Aramid is used in the insulation materials of automotive electrical systems. Its excellent electrical insulation performance can effectively prevent electrical leakage and short circuits, ensuring the normal operation of the vehicle's electrical equipment and improving the safety and reliability of the electrical system. 6. Automotive Air Filtration Systems: Aramid fibers can be used to make air filter materials. Their fine fiber structure and high filtration efficiency can effectively filter out dust, pollen and other impurities in the air, providing clean air for the vehicle interior and protecting the health of passengers.
