Title
(DE) VERFAHREN ZUR HERSTELLUNG VON SMC-HOHLBAUTEILEN
(EN) PROCESS FOR THE PRODUCTION OF SMC HOLLOW COMPONENTS
(FR) PROCÉDÉ DE FABRICATION D'ÉLÉMENTS CREUX EN SMC
Abstract
(DE)
Verfahren zur Herstellung von Faserverbund-Hohlbauteilen, wobei ein SMC geeignetes Faserverbundhalbzeug in einem SMC-Werkzeug über oder um ein Kernsystem angeordnet und durch das SMC-Werkzeug in eine Hohlbauform gepresst wird und das Kernsystem aus einer auswaschbaren Salzbasis gebildet ist.
(EN)
The invention relates to a process for the production of fiber composite hollow components, wherein a SMC-suitable fiber composite semi-finished product is arranged in a SMC tool above or around a core system and is pressed into a hollow mold by the SMC tool, the core system being formed from a leachable saline base.
(FR)
Procédé de fabrication d'éléments creux en composite renforcé de fibres, consistant à disposer un produit semi-fini approprié à base de SMC (sheet molding compound : mélange à mouler en feuilles) sur ou autour d'un système de noyau et à le comprimer au moyen de l'outil de moulage de SMC pour produire un élément creux, le système de noyau étant formé d'une base de sel éliminable par lavage.
