Abstract
A friction lining with a porous fiber layer is described which is characterized in that the fiber layer consists of a sintered fiber structure, preferably made of polyimide fibers.
Claims
exact text as granted — not AI-modified1 . A friction lining with a porous fiber layer, characterized in that the fiber layer consists of a sintered fiber structure made of sinterable fibers.
2 . A friction lining as claimed in claim 1 , characterized in that the fiber structure consists of polyimide fibers and/or polyacrylonitrile fibers.
3 . A friction lining as claimed in claim 1 or 2 , characterized in that the fiber structure consists of a non-woven material.
4 . A friction lining as claimed in claim 3 , characterized in that the fiber structure is arranged as a needled non-woven material.
5 . A friction lining as claimed in claim 1 or 2 , characterized in that the fiber structure consists of a knitted fabric.
6 . A friction lining as claimed in one of the claims 1 to 5 , characterized in that the fiber layer comprises a surface made of sinterable fibers, preferably polyimide fibers, which are scattered onto the fiber structure and are joined to the same by sintering.
7 . A friction lining as claimed in one of the claims 1 to 6 , characterized in that filling materials influencing the frictional properties are incorporated in the fiber structure.
8 . A friction lining as claimed in one of the claims 1 to 7 , characterized in that the fiber structure is sintered and carbonized.Cited by (0)
