How mineral fibres work

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

Adding fibres into a composite increases the strength of the material. In order to optimise the bonding strength between the fibre and the matrix, it is important to make sure that the binders used in the matrix can chemically attach to the fibres.

By surface-treating mineral fibres with coupling agents, optimal chemical bonding can be achieved.

Different survace treatments must be used for different binding systems. For phenolic resin-based formulations, amino-silane coupling agents are good compartibilisers.
