Title
(EN) PROCESS AND APPARATUS FOR FILAMENT WINDING COMPOSITE WORKPIECES
(FR) PROCEDE ET APPAREIL POUR FORMER PAR ENROULEMENT FILAMENTAIRE DES PIECES A USINER COMPOSITES
Abstract
(EN)
A process and apparatus (10) are provided for forming filament wound composite workpieces (20). The process comprises the steps of: providing reinforcement material (40); providing an injection die (50); providing a winding apparatus (60) including a rotatable mandrel (62); passing the reinforcement material (40) through the injection die (50); injecting a resin material into the injection die (50) to impregnate the reinforcement material (40) with the resin material to form impregnated reinforcement material (40a); and winding the impregnated reinforcement material (40a) about the mandrel (62) so as to form a composite workpiece (20).
(FR)
L'invention concerne un procédé et un appareil (10) servant à former par enroulement filamentaire des pièces à usiner composites (20). Le procédé consiste à se procurer un matériau de renforcement (40), une filière d'injection (50), un appareil d'enroulement (60) comprenant un mandrin rotatif (62); Le procédé consiste ensuite à faire passer le matériau de renforcement (40) à travers la filière d'injection (50); à injecter une matière résineuse dans la filière d'injection (50) pour en imprégner le matériau de renforcement (40) et former un matériau de renforcement imprégné (40a); et à enrouler le matériau de renforcement imprégné (40a) autour du mandrin (62) pour former une pièce à usiner composite (20).
