FIELD: turbo-machines.
SUBSTANCE: invention relates to fibrous pre-molded workpiece performing method for making of turbomachine blade made from composite material; wherein method includes performing by three-dimensional weaving of fibrous stock (100) in form of single part with layers of longitudinal threads (c1-c24), interconnected by weft threads (t1-t24) layers of threads, and fibrous workpiece forming to produce fibrous pre-molded workpiece in form of single part, containing part, forming feather pre-molded workpiece, and, at least, one part forming pre-molded platform workpiece. In process of weaving threads (c5-c7) of longitudinal fibers first group come out of fibrous workpiece on side of workpiece one of lateral sides (110a) to form part (120), corresponding to platform pre-molded workpiece, and threads (c3 and c4) of longitudinal threads second group are introduced into fibrous workpiece with mutual intersection between first group threads and second group threads.
EFFECT: invention also relates to pre-molded workpiece, produced by this method.
