Basic Properties Of Paper-based Friction Materials

1. Introduction

Friction material is a kind of component material used in power machinery and relying on friction to achieve braking and transmission functions. Any mechanical equipment and all kinds of moving vehicles must have a brake or transmission device, and the friction material is a key component on this brake or transmission device, which enables the mechanical equipment and various motor vehicles to work safely and reliably .

According to different working environments, friction materials can be divided into dry friction materials and wet friction materials. As the name implies, dry friction materials are generally used in dry environments; wet friction materials refer to friction materials that are in a lubricated state in a sealed environment. Early friction devices mostly used dry friction materials. In recent years, due to their superior performance in reliability, safety and life, wet friction materials have been rapidly developed and are widely used in automobiles, construction machinery, agricultural machinery and various It is used in the braking, clutch and gearbox of various industrial machinery.

At present, there are various classifications of wet friction materials, including paper-based friction materials, sintered metal-based friction materials, carbon-based friction materials, graphite-based friction materials, and rubber-based friction materials. Each friction material has its own functions and advantages. Based on factors such as comprehensive production methods, production costs and service life, paper-based friction materials occupy a relatively large advantage and have been widely used. With the continuous improvement of its formula and production process, modern paper-based friction materials have been widely used in various types of vehicles and construction machinery such as wet braking, clutch and gearbox applications.

2. Basic properties of paper-based friction materials

Paper-based friction material is a material with a network-like porous structure, which is composed of fibers and fillers to form a framework, and is a porous structure formed by resin bonding. This porous structure can store lubricating oil, the paper-based friction material and the friction couple are compressed and deformed when they work, and the lubricating oil inside the material is squeezed to the surface to form a lubricating film; when separated, the paper-based friction material will rebound and recover The original pores and suck the lubricant back into the pores.

3. Application of paper-based friction materials

At present, The paper-based friction materials are used in the brakes, transmissions and other transmission equipment of various vehicles and construction machinery such as construction machinery, agricultural machinery and industrial machinery due to their excellent friction performance. Widely used, it is an important class of friction materials.

The principles of paper-based friction materials in different vehicles (construction machinery, agricultural machinery, etc.) and different applications of vehicles (service brakes, parking brakes, gearboxes, etc.) are different, so We,  A variety of paper materials suitable for different applications have been developed for customers to use for different applications.

4. Conclusion

In order to meet the wider and more demanding conditions, we are also working hard to develop paper-based friction materials with better performance, including wet friction materials with better performance than paper-based friction materials. At present, good progress has been made to provide customers with more choices for better applications.
