The apparatus includes a bottom (12), a top (13), and an outer wall (3) defining an interior space (1) in the apparatus, and a passive heat distribution element (7, 9) located within the interior space (1) and apart from the outer wall (3). Preferably, the bottom (12) and top (12) include perforated plates and the outer wall (3) is cylindrical in shape and all are made of graphite or carbon-carbon composite material and the passive heat distribution element (7, 9) is cylindrical in shape and includes graphite or carbon-carbon composite discs having no spacers therebetween. Also, a method for densifying a porous carbon preform (5), which method includes the steps of: (a) providing the apparatus (11); (b) charging the apparatus (11) with a plurality of stacks of annular porous carbon preforms (5), the preforms being separated from one another by spacers (15); (c) locating the charged apparatus (11) in a furnace at a temperature in the range of 950-1100° C. and a pressure in the range of 5-40 torr; and (d) circulating a natural gas reactant blended with up to 15% propane through the apparatus for 150-900 hours. Also, a batch of carbon-carbon composite preforms made by the method, wherein the density of the batch of preforms is at least 0.5 g/cc higher than the density of a batch of preforms made by an otherwise identical process in which the apparatus does not contain a passive heat distribution element located within its interior. The preforms may be configured as aircraft landing system brake discs or racing car brake discs.

    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.
