Details
The key to industrial progress is the development of material technology, but vibration and noise are filled with industrial life all the time, restricting the development of enterprises and affecting industrial progress.
There are some excellent performance of shock absorption materials on the market, because of good cushioning, wear resistance, fatigue resistance or adjustable widely used, which the characteristics of different materials corresponding to the field is not the same, the following list of some common or potential shock absorption materials in the sports and industrial industry.
1: Rubber
Rubber is a kind of natural or synthetic polymer elastomer, which has good elasticity and fatigue resistance, and is one of the most widely used shock absorbing materials.
Features:
Good elasticity: can deform in a large range and quickly return to the original state.
Fatigue resistance: After repeated compression and release, the performance attenuation is small.
Wear resistance: Good resistance to friction and wear.
Advantages:
Low cost: Natural rubber sources are wide, synthetic rubber is also easier to prepare.
Easy to process: It can be processed into various shapes by injection molding, extrusion, etc.
Applications:
Automotive industry: Used for shock absorbers, suspension systems, etc.
Sports equipment: sports shoes, rackets, etc.
Automotive Suspension Springs
According to statistics, the global rubber cushion income in 2021 is about 17,010 million US dollars, and it is expected to reach 19,550 million US dollars in 2028.
2. Polymer materials
Polymer materials, also known as polymer materials, is a polymer compound as the matrix, and then equipped with other additives (additives) composed of materials, according to the application function classification can be divided into general polymer materials, special polymer materials and functional polymer materials.
Features:
Fatigue resistance: It can maintain stable performance under high-speed collision or multiple impact forces.
Tunability: By changing the molecular structure and crosslinking density, its performance can be optimized.
Stability: Good resistance to temperature, chemical corrosion, etc.
Advantages:
Diverse performance: Material properties can be customized according to requirements.
Good processing performance: It can be processed into complex shapes through a variety of processes.
Applications:
Aerospace: Shock absorption systems used in aircraft and spacecraft.
Electronic equipment: such as mobile phones, laptops earthquake protection.
ACF material (full name "ACF artificial cartilage material") is an advanced invention in the past 10 years. It is a kind of biomimetic energy absorbing material of polymer material. Its principle is to adjust and control its micro and nano structure by imitating human articular cartilage, so that it is infinitely close to articular cartilage structure and has excellent cushioning and energy absorbing property. It is a new star in vibration noise scenes such as sports, industry and automobiles.

Sports equipment: such as golf clubs, bicycle racks, etc.
Automotive Suspension Springs
The application proportion of composite materials in the automotive industry is increasing year by year, and according to Lucintel data disclosed, it is expected that by 2025, the application proportion of lightweight materials in automobiles will exceed 47%.
4. Nanomaterials
Nanomaterials are materials that are between 1 and 100 nanometers in size in at least one dimension.
Features:
Large specific surface area: The number of atoms on the surface of nanomaterials accounts for a large proportion of the total number of atoms, which gives them unique physical and chemical properties.
High interfacial activity: easy to combine with other materials to form composite materials with high interfacial activity.
Advantages:
High performance: Excellent performance in shock absorption and energy absorption.
Diversification: A wide variety of nanomaterials can meet the needs of different applications.
Applications:
Military equipment: Used for shock absorption protection of armored vehicles, tanks, etc.
Sports: such as advanced sports shoes, protective equipment, etc.
Armoured car
Although the application of nanomaterials in the field of shock absorption is relatively small at present, it is growing rapidly and is expected to have significant growth in the next few years.
5. Smart materials
Magnesium-Nickel-Titanium Smart Composites
Smart materials refer to materials that can sense environmental changes and adapt to adjust their own properties, which is the fourth generation of materials after natural materials, synthetic polymer materials and artificial design materials, and is also one of the important directions of the development of modern high-tech new materials.
Features:
Adaptability: Ability to adjust its own performance according to changes in the external environment.
Intelligent: Intelligent control of performance through built-in sensors and controllers.
Advantages:
Highly flexible: able to adapt to different impact environments and conditions.
High efficiency and energy saving: Only activate the shock absorption function when needed to save energy.
Applications:
Aerospace: Shock absorption and protection systems used in aircraft, satellites, etc.
Robotics: Used to improve the stability and safety of robots.
Although the application of smart materials in the field of shock absorption is still in its infancy, its unique properties and huge potential have attracted wide attention and research.
In summary, these shock-absorbing and energy-absorbing materials have their own characteristics and are widely used in different fields. With the advancement of science and technology and the deepening of research, the properties and application fields of these materials will continue to expand and optimize.
