FIELD: technological processes.
SUBSTANCE: invention relates to methods of repair of delaminations in articles made from composite materials. Method of repairing delaminations in an article made from composite material involves drilling one hole in the delamination zone at depth of 0.7–0.8 of the article wall thickness, connecting it to the process gas supply nozzle, then low-pressure gas is fed into said hole, then in delamination zone other holes are drilled in steps of 100–150 mm, at actual depth of delamination to release of gas through said holes, then each drilled hole is closed with a plug, after drilling a sufficient number of plug holes and nozzle from said holes are removed, then adhesive is pumped through one or more holes until it comes out of all holes; then adhesive is polymerised.
EFFECT: said method allows preserving the structure of the material and its strength characteristics.
