METHOD OF LAMINAR MATERIAL FABRICATION Russian patent published in 2015 - IPC B32B27/04 C08J5/24 C08J5/04 

FIELD: process engineering.

SUBSTANCE: invention relates to composites with high mechanical strength to prevent damages caused by striking, particularly, to production of laminates. Prepreg includes a structural layer of conducting fibres containing thermosetting resin fitted in gaps. First outer resin layer contains thermosetting resin and combination of electrically conducting free single threads. The latter are arranged on the surface of interface between said structural layer and resin outer layer. The latter hardening at increased temperature brings about hardened composite. The latter comprises hardened structural layer of compacted conducting fibres and first outer layer of hardened resin. Note here that said outer layer of hardened resin includes a portion of said combination of electrically conducting free single threads dispersed therein. Note here that said combination of electrically conducting free single threads is made of the portion of structural layer of conducting fibres.

EFFECT: light composite of excellent mechanical properties.
