How mineral fibres work

Icon related to working mechanism of lapinus mineral fibres in brake systems. friction material

Noise is a result of vibration propagation. To reduce the propagation of vibration, friction formulations must contain materials with damping properties or they should be able to generate frequencies outside the audible range or beneath the chritical noise decibel level.

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.

Both mechanisms result in an improved noise, vibration and harshness (NVH) performance.
