COMPOSITE MATERIAL Russian patent published in 2023 - IPC C22C49/06 C22C111/00 

FIELD: metallurgy.

SUBSTANCE: production of a casting composite material based on an aluminum alloy, strengthened with reinforcing metal fibers, and can be used in the creation of structures and equipment as structural materials with improved process and operational properties. A composite material based on an aluminum alloy with reinforcing fibers includes a matrix made of aluminum alloy AK7 and a reinforcement made in the form of reinforcing fibers. The fibers are made of copper wire with a length limited by the size of the composite material, and laid along the material at equal distances from each other, while hollow copper spheres with a diameter of 4 mm are strung close to each other on the fibers, and the distance between the reinforcing fibers corresponds to 1-2 diameters hollow copper spheres.

EFFECT: composite material has high strength characteristics.
