ANTIFRICTION COMPOSITE MATERIAL FOR MAKING SHIP FITTINGS Russian patent published in 2012 - IPC C08J5/06 C08L77/12 C08J5/16

Abstract RU 2463321 C1

FIELD: machine building.

SUBSTANCE: invention relates to antifriction composite materials based on thermoplastic polymers and may be used in making highly loaded friction assemblies, particularly, to seals of ship ball valves. Material consists of (in wt %) aromatic partially crystalline linear polymer PEEK 450 PF with reinforcing filler from minced fiber of carbon fabric Ural T-22-30-35. Invention allows friction assembly bearing capacity of 0.8-4.0 MPa at sliding speed of 12 m/c to 0.5 m/s, water absorption of not over 2%, compression resistance of at least 250 MPa, ultimate stress at static flexure at least 160 MPa, and impact strength of at least 21 kJ/m².

EFFECT: improved performances.
