METHOD OF MAKING (PARTIALLY) ANNULAR PARTS CONTAINING SYNTHETIC MATERIAL REINFORCED WITH FIBRES FROM SEMI-FINISHED PRODUCTS OF FIBROUS COMPOSITE Russian patent published in 2014 - IPC B29C70/32 B29C70/34 

FIELD: process engineering.

SUBSTANCE: invention relates to production of semi-finished products of parts thereof from fibrous composites. Proposed method comprises placing of at least one annular or partially annular shaped part on revolving drum to male a coil-like form with annular or partially annular channel section extending radially and/or in lengthwise direction of the drum and application layer-by-layer of semi-finished product on coil-like form channel section. Said steps are reiterated at least once with addition of at least one annular or partially annular shaped part on revolving drum to make another one channel section adjoining the former channel section and to fit semi-finished material in said channel section. Produced set of channel section makes at least partially the form for making the aforesaid part. Matrix material is fitted in channel sections and drum is revolved to make matrix material extruded outward by centrifugal forces while air contained in the channel is forced radially inward. Matrix material in channels is solidified to separate the structure of shaped parts after solidification so that solidified annular semi-finished product or part therefrom.

EFFECT: production of parts of complex cross-section.
