FIELD: machine building.
SUBSTANCE: present invention relates to a composite blade of a turbomachine. In making a turbomachine composite blade a matrix and a reinforcement are produced simultaneously by performing layers on a powder basis. Simultaneous production of the matrix and the reinforcement is carried out by performing repeated steps when a filler material is applied to make the reinforcement, cohesion of the reinforcing filler material is ensured, a matrix forming filler material is applied, and cohesion of the matrix forming filler material is ensured. Herewith application of the filler material forming the reinforcement and application of the filler material forming the matrix is performed simultaneously and/or ensuring cohesion of the reinforcing filler material and ensuring cohesion of the matrix filler material is performed simultaneously. Another invention of the group refers to a turbomachine blade made using the said method and containing a composite material with a matrix and a reinforcement containing a mesh. Blade includes a leading edge, a trailing edge, a trough surface and a back surface extending from the leading edge to the trailing edge. Mesh forms a three-dimensional structure extending over the major part of the blade thickness between the trough surface and the back surface and/or over the major part of the blade length between the leading edge and the trailing edge. Herewith the three-dimensional structure comprises rods fixed in the matrix, wherein the said matrix occupies most of the blade volume.
EFFECT: group of inventions provides higher strength of the turbomachine composite blade.
