Claims (3)

1. Способ изготовления фрикционного изделия, включающий образование исходной композиции посредством механического смешения волокна с пеком, осаждение исходной композиции, формование заготовки изделия прессованием исходной композиции при одновременном воздействии давления и тепла при температуре не ниже температуры размягчения пека, и карбонизацию исходной композиции, отличающийся тем, что заготовку изделия перед карбонизацией под давлением подвергают обжигу и последующей пропитке пеком, а после карбонизации под давлением осуществляют термообработку в режиме обеспечения графитации пека, при этом для образования исходной композиции применяют среднетемпературный пек, а для последующей пропитки заготовки - высокотемпературный пек.1. A method of manufacturing a friction product, including the formation of the original composition by mechanical mixing of the fiber with the pitch, the deposition of the original composition, molding of the product blank by pressing the original composition at the same time pressure and heat at a temperature not lower than the softening temperature of the pitch, and carbonization of the original composition, characterized in that the product blank before calcination under pressure is fired and then impregnated with pitch, and after carbonization under pressure, heat treatment is carried out in the mode of ensuring graphitization of the pitch, while medium-temperature pitch is used to form the initial composition, and high-temperature pitch is used for subsequent impregnation of the workpiece. 2. Способ по п. 1, отличающийся тем, что заготовку изделия после термообработки подвергают, по меньшей мере, одной дополнительной пропитке высокотемпературным пеком с последующей карбонизацией и термообработкой в режиме обеспечения графитации. 2. The method according to p. 1, characterized in that the workpiece after heat treatment is subjected to at least one additional impregnation with a high-temperature pitch, followed by carbonization and heat treatment in the mode of graphitization. 3. Способ по одному из пп. 1 и 2, отличающийся тем, что для образования исходной композиции и последующей пропитки пек и волокно применены при следующем соотношении компонентов, мас. %:
Пек среднетемпературный - 30-40
Пек высокотемпературный - 10-20
Волокно - Остальное3. The method according to one of paragraphs. 1 and 2, characterized in that for the formation of the initial composition and subsequent impregnation of the pitch and fiber are used in the following ratio of components, wt. %:
Mid-temperature pitch - 30-40
High temperature pitch - 10-20
Fiber - Else
