Anchoring Effect

The Anchoring Effect has a positive influence on the friction level:

more anchoring points means a bigger contact area, resulting in enhanced friction level. If managed properly in the formulation, the advantage of having many secondary plateaus results in a less abrasive formulation and a reduction of wear and
vibrations. The best Anchoring effect is achieved by using short fibres that are optimally distributed in the friction matrix.

02

Damping

Mineral fibres can contribute in two ways to reduce the propagation of vibrations:

1. Reducing the generation of vibrations with long fibres through the Reservoir Effect
2. Mineral fibres coated with rubber contribute to the damping properties of the friction material

Both mechanisms result in an improved NVH performance.

03

Reservoir Effect

The Reservoir Effect has a positive influence

on friction level stability, wear and noise reduction.

04

Surface Reinforcement

There are two key ways in which mineral fibres can improve disc pad surface reinforcement by:

1. Working as an anchor to keep all the functions working on the surface;
2. Generating porosities that accumulate other raw materials in the surface, allowing them to work for a longer period of time.

05

Bonding

Different surface treatments must be used for different binding systems.

For phenolic resin-based formulations, amino-silane coupling agents are good compatibilisers.

06

Porosity Contribution

Fibre length, fibre coating, shot content and fibre diameter

are relevant parameters contributing to the generation of porosity.
