High Temperature Roll moulded friction lining

High-temperature roll-molded friction linings are specialized materials used in brake systems, clutches, and other applications where high temperatures are generated during frictional contact. These linings are manufactured through a roll-molding process, which involves compressing and shaping friction materials into the desired form. Here’s an overview of high-temperature roll-molded friction linings:

  1. Manufacturing Process:

    • Roll Molding: The roll-molding process involves compressing friction materials between rollers to form thin sheets or rolls. These rolls can then be further processed and cut to the required shape and size for specific applications.
    • Forming and Shaping: During roll molding, the friction materials are compressed and shaped under pressure to achieve the desired thickness, density, and surface finish. Various additives and binders may be incorporated into the formulation to enhance performance and durability.
  2. Materials:

    • High-Temperature Friction Materials: Roll-molded friction linings are typically composed of high-temperature-resistant materials such as ceramic fibers, aramid fibers (e.g., Kevlar), carbon fibers, and metallic powders.
    • Binders and Additives: Binders and additives are used to improve the bonding strength, wear resistance, and thermal stability of the friction materials. Common binders include phenolic resins, epoxy resins, and rubber compounds.
  3. Temperature Resistance:

    • High-temperature roll-molded friction linings are engineered to withstand elevated temperatures generated during braking and clutch engagement. They can typically withstand temperatures ranging from several hundred to over a thousand degrees Celsius, depending on the specific composition and construction.
  4. Features:

    • Excellent Friction Characteristics: Roll-molded friction linings offer high friction coefficients, providing reliable stopping power and clutch engagement under various operating conditions.
    • Thermal Stability: These linings exhibit excellent thermal stability, maintaining consistent performance and durability even at high temperatures.
    • Wear Resistance: Roll-molded friction linings are designed to withstand repeated frictional contact and exhibit low wear rates, resulting in extended service life and reduced maintenance requirements.
    • Customizable Shapes and Sizes: Roll-molded friction linings can be manufactured in various shapes, sizes, and thicknesses to meet the specific requirements of different brake and clutch applications.
  5. Applications:

    • High-temperature roll-molded friction linings are used in a wide range of applications, including automotive brake pads, industrial brake systems, clutches, power transmission components, and machinery requiring reliable frictional performance at elevated temperatures.

These linings play a crucial role in ensuring the safety, performance, and reliability of braking and clutch systems in various industries. When selecting high-temperature roll-molded friction linings for a specific application, factors such as temperature range, frictional characteristics, wear resistance, and compatibility with mating surfaces should be carefully considered to ensure optimal performance and longevity.
