FIELD: process engineering.
SUBSTANCE: invention relates to production of turbine blower guide vane of composite material. Proposed method comprises making of fiber preform by 3D weaving of one part. Said preform comprises first part extending in one lengthwise axis to make preform for vane airfoil and second part located and lengthwise end forming the preform for vane support. Second part consists of first layer and second layer facing the latter and separated therefrom by separation without cutting in making of preform. Proposed method comprises bending said first and second layers so that each of them is located in plane perpendicular to lengthwise axis, in fact, in symmetry about each other relative to said first part so that firs layer first section overlaps second layer second section ahead of first part edge. This method comprises jointing the preform with the mould to compact the former by polymer female die.
EFFECT: simplified process, higher mechanical strength.
