FIELD: instruments.
SUBSTANCE: invention relates to tool for molding, intended for producing parts from composite material by coating using a matrix, flexible pre-molded stock containing shell and shaped elements limiting several volume cells with a polyhedral shape. Said molding tool comprises a mold and a counter mold made from material, coefficient of expansion of which is similar to coefficient of expansion of pre-molded stock. Tool comprises for each cell volume a part for filling latter, formed by adjacent wedges, intended for mutual connection and a free central volume, and a blocking part designed for relative blocking of blocking part and wedges. Said wedges and locking part are made from material which is characterised by a coefficient of expansion, suitable for reaching preset pressing pre-molded stock at polymerisation matrix temperature.
EFFECT: invention provides high manufacturability of parts from composite material.
