FIBROUS COMPOSITE AND METHOD OF ITS PRODUCTION Russian patent published in 2014 - IPC B29C70/20 B29C70/34 B29B15/12 C08J5/24 D02G3/34 

FIELD: process engineering.

SUBSTANCE: invention relates to production of fibrous composite including the fibres and bonding resin. Said process comprises the steps that follow. a) Application of threads consisting of elementary multiple separate elementary fibres retained by resin cross-linked by at least one physical magnitude and/or one chemical substance. Note here that separate elementary fibres of the thread feature unilateral orientation. b) Said threads are bonded together by their outer side surfaces with the help of bridges. Note here that separate elementary fibres are shifted relative to each other and embedded completely in resin material. Note also that said threads feature no air inclusions. c) After combination of threads in compliance with step (b) resin is cross-linked by at least one physical magnitude and/or one chemical substance to make fibrous composite acquire its final strength. Note that said fibrous composite comprises braiding, knitting, setting, nonwoven material or fabric, preferably, with calico weave. It comprises the threads of substrate and/or weft that make the elementary composite of multiple separate elementary fibres and resin not cross-linked. Note also that said separate elementary fibres of said threads feature unilateral orientation while said bridges are made of resin not cross-linked.

EFFECT: higher elasticity and fluid absorption capacity, hard matrix.
