FIELD: machine building.
SUBSTANCE: invention relates to machine building and can be used in aircraft engineering, transport, construction, power engineering to increase strength and service life of structures made from metal, composite and metal composite materials. Method consists in using nano-modified adhesive composition with calculated combination of maximum strength and maximum impact strength and in assembly of bolted metal composite connection in certain sequence.
EFFECT: technical result is higher strength and fatigue endurance of bolted metal composite connection, preservation of its parameters stability over time, aswell as decreasing concentration of contact and tensile stresses in holes circuit.
