초록 ▼

The present invention relates to a method for producing ceramic articles and the articles, the process comprising the chemical vapor deposition (CVD) and/or chemical vapor infiltration (CVI) of a honeycomb structure. Specifically the present invention relates to a method for the production of a ceramic honeycomb structure, including: (a) obtaining a loosely woven fabric/binder wherein the fabric consists essentially of metallic, ceramic or organic fiber and the binder consists essentially of an organic or inorganic material wherein the fabric/binder has and retains a honeycomb shape, with the proviso that when the fabric is metallic or ceramic the binder is organic only; (b) substantially evenly depositing at least one layer of a ceramic on the fabric/binder of step (a); and (c) recovering the ceramic coated fiber honeycomb structure. In another aspect, the present invention relates to a method for the manufacture of a lightweight ceramic-ceramic composite honeycomb structure, which process comprises: (d) pyrolyzing a loosely woven fabric a honeycomb shaped and having a high char yield and geometric integrity after pyrolysis at between about 700°and 1,100°C.; (e) substantially evenly depositing at least one layer of ceramic material on the pyrolyzed fabric of step (a); and (f) recovering the coated ceramic honeycomb structure. The ceramic articles produced have enhanced physical properties and are useful in aircraft and aerospace uses.

A method for the production of a three-dimensional lightweight ceramic composite honeycomb structure, which method comprises: (a) pyrolyzing a loosely woven fabric/binder having a three-dimensional honeycomb shape and having a high char yield and three-dimensional geometric integrity during and after pyrolysis at between about 700°and 1,100°C.; (b) substantially evenly depositing at least one layer of ceramic material on and within the three-dimensional pyrolyzed fabric/binder of step (a) by chemical vapor deposition and chemical vapor infiltration in a reaction system; and (c) removing the pyrolyzed fabric/binder of the structure of step (b) by slow pyrolysis at between about 700°and 1000°C. in between about a 2 to 5% by volume oxygen atmosphere for between about 0.5 and 5 hr; (d) substantially evenly depositing on and within the rigid hollow honeycomb structure of step (c) at least one additional layer of the same or a different ceramic material by chemical vapor deposition and chemical vapor infiltration; and (e) removing the ceramic article from the chemical vapor deposition-chemical vapor infiltration reaction system.
