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

FIELD: metallurgy.

SUBSTANCE: composite material based on aluminium alloy with reinforcing fibres includes an aluminium alloy matrix and a hardener. The hardener is made in the form of reinforcing fibres. The matrix is made of aluminium alloy AK7. The reinforcing fibres are made of copper wire with a cross section of 0.5 mm and a length limited by the size of the composite material. The reinforcing fibres are laid along the composite material at equal distances from each other. Hollow steel spheres with a diameter of 4 mm are strung close to each other on the reinforcing fibres. The distance between the reinforcing fibres corresponds to 1-2 diameters of the hollow steel spheres.

EFFECT: obtaining a lightweight composite material with improved strength characteristics.
