Friction bearing compound material and friction bearing element made of the same

摘要

The metal/plastic slide bearing composite material (2) comprises a metallic support layer (4) made of steel, and a porous carrier layer (6) with a sintered carrier layer made of metal particles (7), where the pores of the carrier layer are filled with a sliding layer material (8) including polyvinylidene fluoride-based or fluorine-free thermoplastics such as polyphthalamide (PPA), liquid crystal polymer, polyether ether ketone (PEEK), polyphenylene sulfide, polyethylenimine, polyimide (PI). The sliding layer material comprises 1-8 wt.% of multi-walled carbon nanotubes. The metal/plastic slide bearing composite material (2) comprises a metallic support layer (4) made of steel, and a porous carrier layer (6) with a sintered carrier layer made of metal particles (7), where the pores of the carrier layer are filled with a sliding layer material (8) including polyvinylidene fluoride-based or fluorine-free thermoplastics such as polyphthalamide (PPA), liquid crystal polymer, polyether ether ketone (PEEK), polyphenylene sulfide, polyethylenimine, polyimide (PI). The sliding layer material comprises 1-8 wt.% of multi-walled carbon nanotubes with a tube outer diameter of 50 nm and a tube length of = 2 mu m. The carbon nanotubes are oriented towards the sliding stress. The sliding layer material is formed on PEEK or PPA base. The sliding layer material comprises 5-25 mass% of fillers. The sliding layer material forms a projection over the porous carrier layer with the thickness of 80-150 mu m. An independent claim is included for a method for manufacturing a slide bearing composite material.
