MULTILAYER ELEMENT COMPRISING A REINFORCING MATERIAL COMBINED WITH A SUPPORT LAYER BY MEANS OF AN ELECTROSTATIC LINK Russian patent published in 2018 - IPC B32B7/04 B32B5/12 B32B27/36 B29C70/20 B29C39/10 

FIELD: technological processes.

SUBSTANCE: invention relates to reinforcing materials and concerns a multilayer element comprising a reinforcing material combined with a support layer by means of an electrostatic link. Multilayer element comprises a reinforcing material suitable for producing composite parts, wherein the reinforcing material is associated on at least one of its faces with a support layer, the reinforcing material and the support layer are combined by means of electrostatic forces. Invention describes a method for preparing such a material and a method for producing a composite part produced from at least one reinforcing material obtained from such an element, after having removed the support layer.

EFFECT: invention provides a novel method for binding a reinforcing material to a support layer that is easy to implement and that does not lead to any deterioration of the initial reinforcing material, facilitating processing and cutting the reinforcing material, at the same time, it is subsequently possible to exfoliate two components in order to be able to place the reinforcing material in a certain position in producing the composite part.
