Title (EN) ARRANGEMENT, METHOD AND HOLLOW BODY IN CONNECTION WITH FORMING OF PLASTIC COMPONENTS
(FR) SYSTEME, PROCEDE ET CORPS CREUX UTILISES EN ASSOCIATION AVEC LE FORMAGE DE COMPOSANTS PLASTIQUES
Abstract:
(EN) The invention can be implemented in connection with the moulding of plastic components which comprise reinforced plastic. The plastic components in question are hollow or comprise a porous core and are referred to, in accordance with the invention, by the expression hollow bodies. The invention relates to an arrangement for the moulding of hollow bodies which comprise reinforced plastic. The arrangement in this case comprises a flexible pressure membrane and a preformed core which is self-supporting. The invention also relates to a method for the moulding of hollow bodies using an arrangement according to the invention, and to a hollow body which has been moulded according to the method. The invention can be applied within many different areas where there is a need for hollow bodies which comprise reinforced plastic, for example within the area of the manufacture of vehicle components made of reinforced plastic. Among particularly preferred applications, there is the use of hollow bodies according to the invention for load-bearing elements, such as pillars and beams in motor vehicles.
(FR) Cette invention peut être réalisée en association avec le moulage de composants en plastique qui contiennent du plastique renforcé. Ces composants en plastique sont creux ou contiennent un noyau poreux et ils sont appelés, dans cette invention, corps creux. Cette invention se rapporte à un système pour le moulage de corps creux qui contiennent du plastique renforcé. Ce système comporte, dans ce cas, une membrane de pression souple et un noyau préformé qui est autoporteur. Cette invention se rapporte également à un procédé pour le moulage de corps creux au moyen d'un tel système décrit dans cette invention, et à un corps creux qui est moulé selon ce procédé. Cette invention peut s'appliquer à de nombreux domaines différents, nécessitant des corps creux qui contiennent du plastique renforcé, par exemple dans le domaine de la fabrication de composants pour véhicules en plastique renforcé. Parmi les applications particulièrement préférées, on utilise de tels corps creux décrits dans cette invention pour des éléments porteurs, tels que des montants et des éléments de rigidité pour véhicules à moteur.
