Tilting segment and tilting segment sliding bearing
A tilting segment ( 3, 3 ′) for a tilting segment sliding bearing ( 1, 1 ′) has a segment body ( 13, 13 ′) for receiving bearing forces. The segment body ( 13, 13 ′) is made of a fiber-reinforced composite material. The composite material includes a polyether ketone and carbon fibers that function as reinforcement fibers. The carbon fibers make up 25 wt. % to 70 wt. % of the fiber-reinforced composite material. Additionally, the carbon fibers form a fabric. The fabric has a contour that has an orientation that is parallel to a sliding surface ( 8, 18 ) of the segment body ( 13, 13 ′).
