Improved Performance of NAO/Non-Steel Disc Pads By Usage Extreme Low Shot (ELS) Roxul®1000 Fibres 2007-01-3938

Roxul®1000 fibres have been widely used as a reinforcement product for friction materials. Especially in NAO/non-steel disc pad applications Roxul®1000 fibres are an important component of the new generation formulations. Besides reinforcement properties, it was not well understood what the effect of Roxul®1000 fibres on the friction performance is. This paper describes the effect ELS Roxul®1000 fibres have on the most relevant friction parameters of NAO/non-steel disc pad formulations.
It has been observed that ELS Roxul®1000 fibres do not only improve the crack resistance of NAO/non-steel disc pads, but also improve various friction parameters. When including up to 20 volume% Roxul®1000 fibres in a basic NAO/non-steel disc pad formulation both pad and rotor wear are reduced over a broad temperature range, speed and pressure sensitivity are reduced significantly, (first) fade performance is improved drastically and also brake noise is reduced over a broad range of driving conditions.
