METHOD OF MAKING PART FROM COMPOSITE MATERIAL BY INJECTING SLURRY WITH FILLER INTO FIBROUS STRUCTURE Russian patent published in 2020 - IPC C04B35/80 B28B1/26 B28B7/46 

FIELD: production of composite materials.

SUBSTANCE: invention relates to production of part from composite material, including stages, at which fibrous structure (10) is placed in mold (110), containing in its lower part (130) of porous material, on which first side (10b) of structure (10) rests, fluid (150) is pressurized into fibrous structure (10), containing powder from heat-resistant ceramic particles, through part (130) of porous material is carried out drainage of liquid passed through fibrous structure (10), and inside said structure delays powder of heat-resistant ceramic particles by means of said part (10) of porous material. Between bottom (111) of mold (110) and part (130) of porous material there is a rigid open-work element (140), on the lower side of which there are cuts or recesses. After molding, the fibrous workpiece is removed from the mold and heat treated to form a matrix of heat-resistant ceramic particles in the fibrous structure.

EFFECT: technical result of invention is provision of uniform distribution of ceramic particles in fibrous structure.
