FIELD: metallurgy.

SUBSTANCE: invention relates to the field of metallurgy and can be used for manufacturing parts of a gas turbine engine. The method for producing composite cylindrical workpieces for manufacturing a bladed disk of a gas turbine engine includes additive growing of the matrix component of composite workpieces in the form of profiled plates made of a titanium alloy with a wall thickness of 80 to 130 mcm, welding of the grown profiled plates into a continuous tape, winding of the tape into an annular cavity made in the inner part of the cylindrical body of the workpiece made of a titanium alloy, simultaneous laying of a reinforcing component in the form of core fibres of silicon carbide with a diameter of 100 to 145 mcm with a pyrocarbon coating and a volume fraction of 25 to 40% in the composite workpiece into the profiled plates, wherein, at the initial and final stages of winding, the core fibre is mechanically secured with the front and back ends of the continuous tape, subsequent encapsulation of the resulting composite cylindrical workpiece, isostatic pressing of the resulting capsule, and mechanical processing.

EFFECT: optimised process of producing composite cylindrical workpieces, increase in the tensile strength of the reinforced section of the bladed disk, reduction in the weight of turbine parts.
