Title (EN) PROCESS AND SYSTEM OF DEBUNDLING FIBER TOW FOR USE IN PREFORM MATS AND MOLDING COMPOSITIONS CONTAINING SUCH FIBERS
(FR) PROCÉDÉ ET SYSTÈME DE DÉMÊLAGE D’ÉTOUPE DE FIBRE À UTILISER DANS DES TAPIS DE PRÉFORME, ET COMPOSITIONS DE MOULAGE CONTENANT DE TELLES FIBRES
Abstract:
(EN) A system for debundling fiber tow into chopped fibers is provided that has one or more reels of fiber tow, a cutting element configured to receive the fiber tow to form chopped fiber, and a tube with introduced gas flow configured to receive the chopped fiber. A moving belt is positioned under the tube to collect the chopped fiber. A dispenser is positioned along the moving belt for applying a binder or additive. A treatment chamber receives the treated chopped fiber. A process for debundling fiber tow into chopped fibers is provided that supplies one or more reels of fiber tow to a cutting system, drops the chopped fiber into a tube with introduced gas flow to debundle the chopped fiber with a vortex, collects the chopped fiber exiting the tube onto a moving belt, chemically treats the chopped fiber, and provides the chemically treated chopped to a treatment chamber.
(FR) L'invention concerne un système de démêlage d'étoupe de fibre en fibres coupées, qui a une ou plusieurs bobines d'étoupe de fibre, un élément de coupe conçu pour recevoir l'étoupe de fibre pour former une fibre coupée, et un tube à flux de gaz introduit conçu pour recevoir la fibre coupée. Une courroie mobile est positionnée sous le tube pour collecter la fibre coupée. Un distributeur est positionné le long de la courroie mobile pour appliquer un liant ou additif. Une chambre de traitement reçoit la fibre coupée traitée. Un procédé de démêlage d'étoupe de fibre en fibres coupées fournit une ou plusieurs bobines d'étoupe de fibre à un système de coupe, dépose la fibre coupée dans un tube à flux de gaz introduit pour démêler la fibre coupée avec un tourbillon, collecte la fibre coupée sortant du tube sur une courroie mobile, traite chimiquement la fibre coupée, et fournit la fibre coupée traitée chimiquement à une chambre de traitement.
