Abstract: Barium sulfate-containing composites, to methods for producing the same and to the use of said composites.

Abstract: The invention relates to a plain bearing composite material with a metallic base layer, optionally with a porous support layer applied thereto and a lead-free bearing layer, forming a bearing surface for a bearing partner with a bearing surface material made from plastic with PEEK and a lubricant in the form of zinc sulfide and/or barium sulfate. The plain bearing composite material is characterised in that the bearing material comprises PEEK as matrix-forming plastic component and the lubricant is in the form of 3–15 wt. % zinc sulfide and/or barium sulfate and a hardening component in the form of 3–15 wt. % titanium dioxide and additionally 5–25 wt. % carbon fibers and 5–15 wt. % graphite particles.

Abstract: The invention relates to a plain bearing composite material provided with a metallic support layer, optionally with a porous carrier layer applied thereto, and with a lead-free sliding layer, which forms a sliding partner and whose sliding layer material is based on plastic. The aim of the invention is to provide a plain bearing composite material that has a long serviceable life when used a high temperatures. To this end the sliding layer material comprises PEEK as a matrix forming plastic constituent, a lubricant provided in the form of zinc sulfide, a hardening constituent provided in the form of titanium dioxide, and additionally comprises carbon fibers. The weight percentage proportion of the lubricant and of the hardening constituent with regard to the mass of the sliding layer material ranges from 5 to 15% by weight, and the lubricant and the hardening constituent are provided in the form of fine particles having a particle size D50-value of no greater than 500 nm.
