FIELD: manufacturing technology.
SUBSTANCE: invention relates to production of an article from a composite material. Technical result is achieved by a method of production of an article from a composite material, which includes the following steps whereat first mix of first thermosetting resin with long staple fibers is subjected to pre-pressing in definite shape to produce a first workpiece. Then preliminary heat treatment of the first workpiece is performed till the stage of intermediate conversion of the first thermosetting resin corresponding to hardening of the specified first resin. First workpiece is connected to a second workpiece containing a fibrous structure of continuous fibers pre-impregnated with a second thermosetting resin. Further, the first and second workpieces are polymerized to obtain an article from a composite material, containing a body from a composite material containing as a filler continuous fibers connected by organic matrix, having a part of a composite material containing as a filler long staple fibers connected by organic matrix.
EFFECT: high strength of connection of individual components of an article of a complex geometric shape.
