Friction Materials & Friction Material Manufacturers
Friction materials are used in most industries to induce resistance in several applications that require slow or decreased movement, such as in brake and clutch systems. For example, industrial machinery, automotive equipment, operating systems etc. all require the ability to slow down and/or stop their processes. Disc brake pads, friction pads and linings are common components of these arrangements and these are made of friction materials. They are also referred to as brake materials and clutch materials.
Materials used in the production of friction are usually rough or textured in order to provide added friction and increase efficiency. Smooth surfaces are used to transport materials easily and with little friction, however adding texture to a surface increases the energy required to move over it, thus slowing a moving object more quickly. Heat-resistant materials are often utilized as the process of creating friction typically generates heat energy as a byproduct. While asbestos fibers were once the most popular choice for friction materials, due to health concerns about the use of asbestos, there has been a growth in manufacturing of alternatives such as ceramic brake pads. Ceramic is a durable and highly heat-resistant material which allows for its use in many high friction environments. As the process of friction occurs inevitably with wear and tear, the materials used need to be able to withstand a certain amount of physical stress. There are several applications for which friction materials are essential. Brake pads, clutch sets, brake bands, brake lining, clutch facing, disc brake pads, clutch discs and friction discs, brake shoes and brake blocks all demand friction materials in order to operate at optimum levels. These materials are utilized by a variety of industries such as mining, oil and gas, forestry and construction. The automotive industry relies heavily on these friction material components as well.

Friction is defined as the resistance to relative motion that opposes the travel direction of an object. At its most simple, it is used to slow an object down enough to stop it, or to bring it to a controllable speed. It is created by contact of one solid body with a divergent surface. The type of material suited to a given task is dependent upon the type of friction. Different types of friction include static, kinetic and rolling. Static friction is found between two solid objects that are not moving relative to each other, preventing movement entirely. Slope is an important consideration when utilizing this particular type of friction. Kinetic friction, also known as dynamic, occurs between two objects moving relative to each other. Both surfaces may be moving or one may be sliding along a stationary object. Rolling friction involves wheels or balls. The rough texture of friction materials catches the wheel and stops it from sliding or slipping. A car tire spinning on ice or snow, for instance, is an example of low rolling friction and thus the tire does not catch on the ground, but keeps moving around.
A high coefficient of friction and good energy absorption are the key requirements of all friction materials. It is necessary to know the system for which the material is needed in order to ensure efficiency and effectiveness. In instances where quick stopping is an issue, a material that creates a large amount of friction is needed. In addition to speed, heat generation is an important consideration. Resin bonded asbestos and carbon was once the most popular friction material, but recent technological advances have significantly expanded material possibilities. Ceramic, as aforementioned, has become a popular choice due to its desirable attributes. Semi-metallic brake elements are also available using copper, brass and steel wool bonded by resin as these compounds share many of the long-lasting characteristics of ceramic options.
Braking systems use friction materials to slow and stop wheels and other mechanisms from moving. When a brake is pressed, it activates a system that places friction material against the moving disc in order to slow the connected tire. Friction discs are most often constructed of durable metal. The drawback of metallic components is the inherent grinding noise created by their friction. For this reason several manufacturers coat them with rubber and other high friction materials. Rubber or other materials have the added benefit of increased surface friction. Brake pads, linings, blocks and shoes are different mechanisms engaged by the action of braking which presses them against the disc. Clutch facing and discs function in a similar manner to offer consistent clutch engagement and disengagement. Although it is an important aspect of many other industries, the production of friction materials has more recently become an industry in its own right. While generalizations can be made, manufacturers are often secretive of their specific friction material compositions. The major changes in the industry throughout the years have caused several companies to try and protect their own advancements in order to beat out competitors. The introduction of ceramics, for example, has provided several opportunities for efficient and reliable systems. Faster stopping and lower noise are common claims in brake and clutch related products. Friction materials continue to advance and developments are a consistent occurrence in the industry markets.
