Influence Thermo-mechanical Treatment Carbon-plastic on the Reduction Mechanical Stresses during Carbonization

The main lack of the carbon-carbon materials based on phenolic resins is long tine of its preparing. It is connected with low speed of temperature rising on the level of carbonization (3...6 K/h). It can be explained by the jact, that it is impossible to exceed ultimate stress limit of the material by the internal stresses, which appear during carbonization. It is determined that carrying out of the thermo-mechanical treatment of carbon-plastic, based on novolac phenolic resins under temperature 730 K gives possibility to enlarge the speed of temperature rising till 100 K/h, without deterioration of mechanic qualities of carbonized material. It allows to define new requirement to carbon-plastic as a body to produce carbon-carbon compositional material: conditional of carbon coming out must provide development of minimal stresses in size during the following high-temperature treatment
