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 with hollow copper spheres strung close to each other. One half of the fibres is made with hollow copper spheres 2 mm in diameter. The second half of the fibres is made with hollow copper spheres 6 mm in diameter. The length of the reinforcing fibres is limited by the size of the composite material. Laying of reinforcing fibres with spheres of different diameters is carried out in a checkerboard pattern.
EFFECT: obtaining a lightweight composite material with improved strength characteristics.
