METHOD OF ARTICLES PRODUCING FROM CARBON FIBRE AND ARTICLE PRODUCED USING SAID METHOD Russian patent published in 2017 - IPC B29C70/46 

FIELD: machine building.

SUBSTANCE: invention relates to thermal compression molding method for making articles from composite materials. Method of thermal compression molding for making articles from composite materials, which involves stages, on which providing mold with molded surfaces, in which article to be produced negative shape is formed. Determining volume of article, to be produced. Calculating sheet molding material (SMC) semi-finished product weight, to be introduced into mold, based on volume of article, to be produced. At that, SMC semi-finished product contains one or more sheets of composite material, containing matrix from heat-curable resin and carbon fibres. Calculating, based on SMC semi-finished product calculated weight, SMC semi-finished product surfaces size, covering mold molded surfaces, when SMC semi-finished product is introduced into mold. Mold is preheated to temperature, making it possible to provide thermally cured resin curing. SMC semi-finished product is introduced into mold. At that, SMC semi-finished product surfaces cover mold molded surfaces in percentage, making from more than 80 % to less than or equal to 99 %. Closing mold, placing mold in autoclave, performing compression cycle in autoclave according to specified pressure on time dependence, opening mold and removing product.

EFFECT: technical result is minimization of articles surface defects formation.
