METHOD OF MAKING THE PART OF FIBROUS COMPOSITE/FIBROUS COMPOSITE PLASTIC FROM ROVINGS WITH THE HELP OF FORMING TOOL AND FORMING TOOL TO THIS END Russian patent published in 2014 - IPC B29C70/38 

FIELD: process engineering.

SUBSTANCE: in compliance with proposed method, at least one roving made of dry fibres is applied on forming surface by applicator and fed between guides in preset directions, said guides being arranged sideways of convexed surface and there along. Rovings between said guides are stretched along forming surface to cover, at least, parts of said forming surface. Binder is applied on stretched rovings. The structures of rovings and binder are consolidated by temperature to make preforms for part to be produced. Preforms are removed from guides and detached from forming tool. Said part is produced by injection or infusion.

EFFECT: higher quality.
