METHOD OF PRODUCING COMPOSITE MATERIAL Russian patent published in 2012 - IPC B29C70/62 

FIELD: process engineering.

SUBSTANCE: set of inventions relates to methods of producing composite materials and device to this end. Proposed method comprises building up layer of reinforcing material, impregnating said layer with matrix and orienting reinforcing layer by applying electromagnetic field in building up of reinforcing layer at acute angle to reinforcing layer. Note here that formation of the layer of catalyst particles for catalysis of building up of reinforcing layers may be conducted by spraying fluid drops on surface. Note also that fluid contains catalyst particles in suspension or solution. Proposed method may also include making two or more sheets of composite material. Note that every sheet is manufactured by building up reinforcing material layer and impregnating it with matrix. Then sheets are folded together to produce laminar structure. Proposed device comprises system for building up layer of reinforcing material, electrode to apply electromagnetic field at acute angle to said layer, and system for applying matrix material on the layer so that impregnate every layer with matrix material. Besides, said device may incorporate printing head to make layer of catalyst particles for catalysis of reinforcing layer building up by spraying fluid drops onto surface through printing orifice.

EFFECT: lower process temperatures, possibilities of latch-batch production.
