Abstract
1. Способ изготовления изделий из композиционного материала, включающий изготовление заготовки из пористого углеродсодержащего материала, армированного термостойкими волокнами, и ее силицирование паро-жидкофазным методом путем нагрева в вакууме или при атмосферном давлении в инертной среде в парах кремния до 1700-1850°C, выдержки в указанном интервале температур и давлений и охлаждения, отличающийся тем, что заготовку изготавливают из материала с ультратонкой открыто-пористой структурой, нагрев ее в интервале 1300-1500°C осуществляют при давлении в реакторе не более 36 мм рт.ст. при температуре паров кремния, превышающей температуру заготовки, а нагрев до температуры 1700-1850°C и изотермическую выдержку в указанном интервале температур проводят в вакууме или при атмосферном давлении в инертной среде в отсутствии указанного перепада температур.2. Способ по п.1, отличающийся тем, что нагрев заготовки в интервале 1300-1500°C осуществляют при температуре паров кремния, превышающей температуру заготовки на 20-150°; при этом меньшей температуре соответствует больший перепад температур и наоборот: большей температуре - меньший перепад температур.1. A method of manufacturing products from composite material, including the manufacture of a preform of a porous carbon-containing material reinforced with heat-resistant fibers, and its silicification by the vapor-liquid-phase method by heating in vacuum or at atmospheric pressure in an inert medium in silicon vapors up to 1700-1850 ° C, exposure in the specified temperature and pressure and cooling range, characterized in that the preform is made of a material with an ultrafine open-porous structure, its heating in the range of 1300-1500 ° C is carried out at a pressure The reaction rate in the reactor is not more than 36 mm Hg. at a temperature of silicon vapor exceeding the temperature of the preform, and heating to a temperature of 1700-1850 ° C and isothermal exposure in the indicated temperature range is carried out in vacuum or at atmospheric pressure in an inert medium in the absence of the indicated temperature difference. 2. The method according to claim 1, characterized in that the heating of the preform in the range of 1300-1500 ° C is carried out at a temperature of silicon vapor exceeding the temperature of the preform by 20-150 °; at this lower temperature, a larger temperature difference corresponds and vice versa: a higher temperature corresponds to a lower temperature difference.
