Title
(EN) METHOD AND SEMI-FINISHED ITEM FOR PRODUCING COMPOSITE PRODUCTS AND THE PRODUCTS THUS OBTAINED
(FR) PROCÉDÉ ET ARTICLE SEMI-FINI PERMETTANT DE FABRIQUER DES PRODUITS COMPOSITES, ET PRODUITS AINSI OBTENUS
Abstract
(EN) A method for producing products made of composite material, comprising the following operating steps: - placing between a first mould (12) and at least a second mould (23) at least one layer (1) of composite material fibre fabric and at least a first layer (16) of composite material fibres, wherein a layer (3) of non-polymerized, composite material resin, substantially free of hardener, is placed between the fabric layer (1) and the first mould (12); - injecting resin and hardener between the first mould (12) and the second mould (23) to impregnate the layer (1) and the first fibre layer (16) with the injected resin and polymerizing the injected resin and the resin layer (3) with the injected hardener. This description also relates to a semi-finished item which can be used in this method and to a product made using this method and/or with this semi-finished item.
(FR) La présente invention concerne un procédé de fabrication de produits en matériau composite, comprenant les étapes de fonctionnement consistant à : - disposer entre un premier moule (12) et au moins un second moule (23) au moins une couche (1) de tissu de fibres de matériau composite et au moins une première couche (16) de fibres de matériau composite, une couche (3) de résine de matériau composite non polymérisée, sensiblement exempte de durcisseur, étant disposée entre la couche de tissu (1) et le premier moule (12) ; - injecter la résine et le durcisseur entre le premier moule (12) et le second moule (23) pour imprégner la couche (1) et la première couche de fibres (16) avec la résine injectée et polymériser la résine injectée et la couche de résine (3) avec le durcisseur injecté. La présente invention concerne également un article semi-fini qui peut être utilisé dans ce procédé et un produit fabriqué à l'aide de ce procédé et/ou de cet article semi-fini.
