Source: Carlisle Brake & Friction

SOLON, Ohio – Carlisle Brake & Friction announced the launch of the company’s next generation of friction materials, including N-680 and EPD (Energy, Power, Dense) for use in brake and transmission applications. The announcement marks Carlisle’s largest advancement in friction material development during the past 15 years.   

The company’s next-generation friction technology offers a much higher energy capability and stability versus previous premium grades of friction materials. The benefits of the new technology include:

Much higher abuse resistance for demanding applications.

Stable and predictable wear across multiple energy conditions, improving preventative maintenance planning.

Much higher energy capacity, allowing for reduction in disc size, or number of discs required in the stack.

Improved drive system power output without the need to up size drive components or systems.

N-680 Paper Friction

Carlisle’s N-680 is the next evolution in wet paper friction material technology. N-680 completes Carlisle’s current range of wet friction materials by increasing energy, stability and overall performance. N-680 friction material offers similar characteristics to N-653 and N-670 as a design replacement, with increased energy and stability. Overall, N-680 is a significant improvement upon current market leading materials, in terms of friction stability, hot spots, and NVH (noise, vibration, harshness).

EPD Material

Carlisle’s EPD friction material family represents the next generation of wet friction material development. EPD technology delivers advanced high-energy performance, reduced wear, improved NVH, and improved material durability/fatigue resistance versus traditional wet friction materials. This material family sets a new standard for energy management of friction materials in a wet application. Providing system design teams with the option to increase power output without adjusting system size, or the ability to reduce system component sizing, without sacrificing system power output.
