What are the characteristics of new materials

The characteristics of new materials are: high strength, high stiffness, high hardness, high temperature resistance, wear resistance, corrosion resistance, radiation resistance and so on.

With the development of science and technology, people have developed new materials on the basis of traditional materials and the research results of modern science and technology. New materials are divided into four categories: metal materials, inorganic non-metallic materials (such as ceramics, gallium arsenide semiconductors, etc.), organic polymer materials and advanced composites.

For example, the successful development of ultrapure silicon and gallium arsenide has led to the birth of large-scale and very large-scale integrated circuits, and the computer operation speed has increased from hundreds of thousands of times per second to more than 10 billion times per second; When the working temperature of aeroengine materials increases by 100 ℃, the thrust can increase by 24%; Stealth materials can absorb electromagnetic waves or reduce the infrared radiation of weapons and equipment, making it difficult for the enemy detection system to find and so on.

Technology of new materials:

New material technology is a technology that can create new materials that can meet various needs through a series of research processes such as physical research, material design, material processing, test evaluation and so on. According to the properties of materials, new materials are divided into four categories: metal materials, inorganic non-metallic materials (such as ceramics, gallium arsenide semiconductors, etc.), organic polymer materials and advanced composites.

According to the service performance of materials, there are structural materials and functional materials. Structural materials mainly use the mechanical and physical and chemical properties of materials to meet the performance requirements of high strength, high stiffness, high hardness, high temperature resistance, wear resistance, corrosion resistance, radiation resistance and so on. Stealth materials can absorb electromagnetic waves or reduce the infrared radiation of weapons and equipment, which makes it difficult for the enemy detection system to find.
