2017 Guangzhou International Auto Show New Materials Area highlights car first look
Lightweight car:
Car lightweight, is to ensure the car's strength and safety under the premise of reducing the car's weight as much as possible to improve the car's power to reduce fuel consumption, reduce exhaust pollution.Experiments have shown that if the car 10% less weight, 6% -8% more fuel efficiency, 0.3-0.6 liters for 100 kilometers less fuel per 100 kilometers, 1% less weight for a car and 0.7% less fuel. Thanks to environmental and energy savings Needs, the automobile light weight has become the trend of the world automobile development.
As the source of design, materials have become the key link in the green supply chain system construction in the automobile industry. The huge market potential of automobile lightweight also attracts many material manufacturers.
The main vehicle lightweight ways are: to optimize the structural design of vehicles, the use of lightweight materials, improve the manufacturing process.
New car material:
The key to reducing the weight of a car is the widespread use of lightweight materials.With the body of the material, for example, the body requires high strength, high precision, high crashworthiness, its quality accounts for about 20% to 25% of the total mass of the car. Said that steel is still the main material for mass-produced net bodies, but with the development of science and technology, the proportion of other new materials, such as aluminum and magnesium alloy materials, will increase. The use of lightweight materials can be significantly reduced This will not only reduce the vehicle manufacturing costs, but also can greatly reduce the cost of vehicle use.
In the future development of the automotive industry, a major trend in the development at home and abroad is to manufacture parts with polymer materials for three main reasons: First, to reduce the quality and reduce costs; second, a component can focus on a number of functions; Third, parts The design has a wide range of free space Therefore, the polymer material components have not only limited to the interior and exterior decoration, but to the body structure and cover the direction of development.Many car companies are even using composite materials to do the most bearing capacity Chassis frame These applications play an important role in reducing weight, reducing noise and improving corrosion resistance.
