摘要： Method for densifying porous carbon preforms. The method including: providing an apparatus charged with at least one stack of annular porous carbon-carbon composite preforms, the preforms being separated from one another by spacers emanating from a passive heat distribution element centrally located within a cylindrical space formed by the stack of annular preforms; locating the charged apparatus in a furnace at a temperature of 950-1100° C. and a pressure of 5-40 torr; and circulating a carbon-containing gas reactant through the apparatus for 150 to 900 hours. Also, an apparatus for practicing this method. The preforms are densified with less physical damage due to the weight of the preforms being treated than are preforms made by otherwise identical processes that do not separate preforms from the preforms immediately above and below them by spacer elements comprising tabs or shelves emanating from a central passive heat distribution structural member.

摘要： Method of chemical vapor infiltration of a deposable carbon material into a porous carbon fiber preform in order to densify the carbon fiber preform. The method includes the steps of: situating the porous carbon fiber preform in the reaction zone; providing a linear flow of a reactant gas comprising deposable carbon material in the reaction zone at an initial reaction pressure of at most 50 torr to produce deposition of the deposable carbon material into the preform; and adjusting the pressure of the gas to reaction pressures lower than said initial reaction pressure while deposable carbon material continues to be deposited into the porous carbon fiber preform. This method enables attainment of a target increased density in a carbon fiber preform much more quickly than known processes. A programmed pressure swing throughout the CVI/CVD run may be set in order to provide a linear increase in density. Alternatively, step changes in pressure during the course of the densification process may be made to enhance the rate of densification. This method reduces the number of cycles and the required intermediate machining steps necessary to densify preforms.
