FIELD: metallurgy.
SUBSTANCE: method for obtaining composite material based on an aluminium matrix involves obtaining of a mixture of aluminium powders or its alloy and carbon nanotubes, sintering of the obtained mixture with formation of a briquette with its further rolling; with that, the mixture of powders is sintered by hot pressing in protective medium at the temperature comprising 0.6-0.99 of the melting temperature of aluminium powder or its alloy, and at pressure of 20-100 MPa during 10-300 minutes; the formed briquette is subject to cold rolling.
EFFECT: invention allows reducing the time for obtaining composite material and providing high mechanical properties.
