An actual scientific and practical problem has been solved concerning the development and application of high-strength antifriction polymer materials in shipbuilding and power machine building. UGET carbon plastics and FUT carbon glass plastics as well as their modifications for friction units with water lubricant exceed traditional polymer antifriction materials in strength and wear resistance. Their advantages are high vibrodamping characteristics, ability to reliably work under dynamic loads and high hydrostatic pressures at the presence of any lubricant (water, acids, alkali, oils, hydraulic liquids, etc.) with counterbodies of various materials (steel, bronze, titanium alloys, ceramics, etc.). The application of sliding bearings made of UGET and FUT carbon plastics makes possible: (1) the creation of new constructions of ship propeller-rudder complexes that meet modern requirements on ecological safety, carrying capacity, and service life; (2) an increase in reliability, ecological safety, and service life of friction units of hydraulic turbines and pumps and thus in their competitiveness on world market; (3) a reduction in damages and expenditures on repair of machines and mechanisms. Technical documentation including standard conditions on materials and articles as well as standards on the technology of articles manufacture using the materials have been developed. The Russian Sea Register of navigation has certified UGET and FUT materials. The workpieces made of the UGET and FUT materials are manufactured on the experimental plant of the Prometei Central Research Institute. UGET and UGET-N epoxy carbon plastics are efficient in heavy-duty slow-moving bearings operating under contact pressures of up to 60 MPa and sliding velocities of up to 1 m/s under water lubrication or without lubrication at velocities of up to 0.2 m/s, i.e. in ship mechanisms and systems of hydraulic turbines, pipeline equipment, contact power networks of railroads, etc. FUT phenol carbon plastic and its modifications FUT-F, FUT-N, FUT-B83, and FUT-F40G40 are efficient in high-speed bearings operating under contact pressures of up to 2-5 MPa and sliding velocities of up to 40 m/s when lubricated by water, oil products and aggressive liquids, viz. in journal bearings of ship shafts lines, face and radial seals of hydraulic turbines, bearings, and face seals of pumps.
