Friction

For over 25 years, leading auto OEMs have relied on AvCarb® Wet Friction Materials for long-lasting high-performance friction systems.
Woven carbon fiber fabric, infiltrated with phenolic resin matrix, and formed to highly uniform thicknesses, provides a durable friction surface suitable for even the most demanding wet friction applications. In typical wet friction systems, AvCarb materials provide a highly stable coefficient of friction, typically between 0.11-0.13 depending on geometry and transmission fluid. AvCarb Wet Friction Products are provided in a fully cured sheet form with or without adhesives. Other versions are available (e.g. partially cured prepreg). Typical applications include torque converter clutches (TCC), automated manual transmissions (AMT), dual clutch transmissions (DCT), manual transmissions (MT), wet brakes in heavy duty vehicles, spindle drives in automatic lift-gate systems.

Benefits:

  • Low wear over lifetime
  • Stable friction coefficient
  • Rapid heat dissipation
  • High compressive strength
  • Thermal stability

Product Formats:

  • Partially cured prepreg (final cure during bonding)
  • Fully cured, precession molded sheets
  • With or without adhesive

Applications

  • Torque Convertor Clutches
  • Cone Synchronizer Clutches

    • Dual clutch transmissions (DCT)
    • Manual transmissions (MT)
    • Automated manual transmissions (AT)

  • Limited Slip Differentials
  • Heavy Duty Wet Brakes
  • Spindle drive brakes used in automatic lift-gates
  • Many other auto and truck applications
