METHOD AND DEVICE FOR PRODUCTION OF COMPOSITE MATERIAL Russian patent published in 2020 - IPC B29B15/08 B29C39/10 B29C70/16 

FIELD: chemistry.

SUBSTANCE: invention relates to method and device for production of composite material. According to the composite material production method, the non-activated powdered adhesive is applied on at least one surface of multiple sheets of carbon fibre; carbon fibres are layered to form laminated material; at least a fragment of powdered adhesive, which is applied between layers of laminated material, is removed by means of air flow, which flows from one surface to another surface of laminated material, to form pre-moulded workpiece, having first area, in which activated adhesive is impregnated into layered material, and second area, in which density of glue content is less than density of content in first area.

EFFECT: invention provides a method of production, by means of which it is possible to mould preformed workpiece without creases or folds formation and formation of composite materials in relatively short period of time, providing impregnation with resin independently from fragment of preformed workpiece, with the help of non-activated powdered adhesive.
