    摘要： A method of manufacturing a carbon-based tooling for use as the support during melt infiltration processing of a prepreg preform used, for example, to manufacture turbine engine components, comprising forming an admixture of chopped carbon fibers, graphite powder and a high durometer thermosetting organic resin, applying a potion of the admixture at room temperature onto the surface of an aluminum die, initially curing the admixture as applied to the aluminum die for a period of 3-5 hours at a temperature of between about 100 and 200 degrees C., removing the carbon-based tooling from the aluminum die and carbonizing the tooling by heating the initially cured tooling to a temperature of about 750 degrees C for a period of about 40 hours. The carbon-based tooling according to the invention retains its shape-maintaining function during the high temperature melt infiltration and does not require subsequent machining after formation, thereby providing a rapid, cost-effective method for creating a carbon-based support tool that remains stable at high temperatures.

    摘要： A method of producing a CMC article having a net shape, and by which the article can be formed to have an exterior surface with desirable characteristics, such as being free of an imprint pattern of a fiber reinforcement material within the article. The method entails providing a body comprising the fiber reinforcement material, and depositing a coating on a surface of the body. The coating contains a carbonaceous binder and a slurry containing a ceramic particulate material. Following its deposition, the carbonaceous binder within the coating is cured to render the coating machinable, and the coating is then machined to approximately produce the net shape of the article.
