METHOD FOR PRODUCTION OF ARTICLES FROM CARBON-CARBONACEOUS COMPOSITE Russian patent published in 1995 - IPC

FIELD: aircraft and chemical industries. SUBSTANCE: method involves assembling a blank, molding and high-temperature treatment by passing electric current through a layer of carbonaceous fabric and is characterized in that the carbonaceous fabric is placed during blank assembly between prepreg layers so that the ends of said fabric protrude beyond the boundaries of the blank. The fabric is molded jointly with the article, protruding ends of the fabric are used during heat treatment as current leads. Uniform current density across the section of the article is ensured by selecting an appropriate number of current leads and their cross sectional area in proportion to the cross sectional area of the article. After heat treatment the current leads are removed from the article. EFFECT: higher efficiency. 2 cl, 1 dwg
