FIELD: production of composite materials; textile industry.
SUBSTANCE: three-dimensional workpiece with a filled gap and a method for forming a three-dimensional workpiece with a filled gap. Blanks include base section (200) consisting entirely of layers woven as a whole, wherein section of said base is divided into three sections: two outer sections (212, 214), containing woven layers as a whole, and middle section (210) containing the gap filler included in it. Gap filler included in workpiece composition may comprise central section from one woven layer; layers woven separately; layers woven as a whole; or multiple layers of warp fibers not entangled with weft fibers. Layers of gap filler included in composition of blank are pressed or pressed into middle section, and they fill formed gap or gaps, while woven layers of external sections are bent to create workpiece shape.
EFFECT: present invention is aimed at providing 3D woven workpiece, the gaps of which are filled with an integral part of the workpiece therewith, without the need for additional material and associated increase in localized thickness, additional mass and reduced structural integrity.
