Hello everyone, today we're going to talkWhat new materials will be used in the future to make cars?。As an indispensable means of transportation in our daily life, the selection and application of materials directly affect the performance, safety, comfort and environmental protection of automobiles. With the advancement of science and technology and the development of society, automotive materials are constantly innovating and changing to meet people's higher requirements for automobiles. So, what materials will be used to build the cars of the future? Below, I will introduce you to several new materials that are expected to be widely used in future automobiles.
Carbon fiber composite material is a composite material composed of carbon fiber and resin and other matrix materials, which has excellent properties such as light weight, high strength, high toughness, high heat resistance, high corrosion resistance, etc., and is an ideal automotive lightweight material. Carbon fiber composite materials can be used to make the body, doors, roof, bumper, chassis, engine cover and other parts of the car, which can greatly reduce the weight of the car and improve the power performance, fuel economy and safety of the car. It is reported that carbon fiber composite materials can reduce the weight of the car by more than 40%, and every 100 kg of weight can be saved3-0.Fuel consumption of 5 liters. At present, some high-end car brands, such as BMW, Audi, Tesla, NIO, etc., have begun to apply carbon fiber composite materials on some models. With the development of the carbon fiber industry and the reduction of costs, carbon fiber composite materials are expected to be more widely used in future automobiles.
High-performance fibers refer to synthetic fibers with special functions and excellent properties, such as aramid, carbon nanotubes, graphene, etc. High-performance fibers can be used to make tires, seat belts, airbags, brake pads, transmission belts and other components of automobiles, which can improve the wear resistance, high temperature resistance, impact resistance, flame retardancy, etc. of automobiles. For example, aramid is a kind of high-strength, high-modulus, high-toughness synthetic fiber, its strength is 5 times that of steel, the modulus is 2 times that of steel, and the specific gravity is 1 5 of steel, which can be used to make tires, seat belts, airbags, etc., which can improve the safety and comfort of automobiles.
Carbon nanotubes are a nanoscale tubular structure composed of carbon atoms, which has the characteristics of high strength, high electrical conductivity, high thermal conductivity, and high specific surface area, and can be used to make batteries, sensors, displays, etc., which can improve the intelligence and electrification level of automobiles. Graphene is a two-dimensional material composed of a single layer of carbon atoms, which has ultra-high strength, hardness, toughness, electrical conductivity, thermal conductivity and other properties, which can be used to make lubricants, coatings, composite materials, etc. for automobiles, and can improve the wear resistance, corrosion resistance, and antistatic properties of automobiles.
Light alloy materials refer to alloy materials based on light metals such as aluminum, magnesium, and titanium, which have the advantages of low density, high strength, high toughness, high electrical conductivity, high thermal conductivity, and high corrosion resistance, and are a lightweight material widely used in automobiles. Light alloy materials can be used to manufacture the body, wheels, engine, gearbox, chassis, suspension and other parts of the car, which can effectively reduce the weight of the car and improve the power performance, fuel economy and environmental protection of the car. For example, aluminum alloy is an alloy material with aluminum as the main component, its density is 1 3 of steel, and the strength is 1 2 of steel, which can be used to make the body, wheels, engine, etc. of automobiles, which can reduce the weight of automobiles by 10%-20%.
Magnesium alloy is an alloy material with magnesium as the main component, and its density is 2 3 of aluminum, and its strength is 1 of aluminum2 times, which can be used to make the gearbox, chassis, suspension, etc. of the car, can reduce the weight of the car by 15%-25%. Titanium alloy is an alloy material with titanium as the main component, its density is half of steel, and the strength is 2 times that of steel, which can be used to make the engine, turbine, exhaust pipe, etc. of automobiles, which can reduce the weight of automobiles by 30%-40%.
In short, the future cars will be manufactured using more new materials to achieve lightweight, intelligent, electrified and environmentally friendly vehicles. These new materials can not only improve the performance and safety of automobiles, but also reduce the cost and energy consumption of automobiles, bringing new opportunities and challenges to the development of the automotive industry.
