FIELD: machine building.
SUBSTANCE: turbomachine blade from composite material is equipped with wing and contains first resin reinforced with long fibres, and second resin reinforced by short fibres. First and second resins are chemically compatible or identical. Long fibres are used to increase rigidity of blade, and short fibres dispersed in second resin serve for filling parts of blade, not reinforced be long fibres, and make final blade shape. Long fibres are arranged in intermediate position between edge zone of shell and core of blade. Short fibres are located in core of blade and between intermediate position and end zone of shell. Another invention of group refers to turbomachine stage containing blades made as described above.
EFFECT: group of inventions enables reducing weight of blades and simplifying their manufacturing.
