Title (EN) PULTRUSION HEAD TO PRODUCE LONG FIBRE REINFORCED THERMOPLASTIC MATRIX PROFILES
(FR) TETE DE PULTRUSION PERMETTANT DE PRODUIRE DES PROFILES A MATRICES THERMOPLASTIQUES RENFORCEES DE FIBRES LONGUES
Abstract: front page image
(EN)The present patent refers to the development and fabrication of a pultrusion head (1) to produce composite profiles from thermoplastic powder coated fibre tows (2) (towpregs). Mounted in a conventional thermosetting comprosite pultrusion machine, the head (1) allows to produce continuous of long fibre reinforced thermoplastic profiles when fed with powder coated fibre tows. The head (1) is composed by three main components: a pre-heating furnace (3), a consolidation die (4) and a cooling die (12). Carbon and glass fibre reinforced 24x4x2 (mm) U-shaped profiles based on polycarbonate (PC) and polypropylene (PP) matrices, respectively, were already successfully pultruded at linear production rates varying from 0.2 to 2 m/min.
(FR)La présente invention concerne la mise au point et la fabrication d'une tête de pultrusion (1) destinée à produire des profilés de composites à partir de câbles (2) de fibres revêtus de poudre (préimprégnés). Montée dans une machine de pultrusion de composites thermodurcissables traditionnelle, la tête de l'invention (1) permet de produire de façon continue des profilés thermoplastiques renforcés de fibres longues lorsqu'elle est alimentée en câbles de fibres revêtus de poudre. La tête de l'invention (1) comprend trois composants principaux : un four de préchauffage (3), une matrice de consolidation (4) et une matrice de refroidissement (12). La tête de l'invention a déjà permis la pultrusion de profilés en U en fibres de carbone et de verre renforcées 24x4x2 (mm) à matrices, respectivement, de polycarbonate (PC) et de polypropylène (PP), à des taux de production linéaires compris entre 0,2 et 2 m/min.
