Title (EN) METHOD AND APPARATUS FOR MANUFACTURING A BODY MADE OF COMPOSITE MATERIAL PROVIDED WITH AN INNER CAVITY WITH AN OUTWARD OPENING
(FR) PROCÉDÉ ET APPAREIL POUR LA FABRICATION D'UN CORPS DE MATÉRIAU COMPOSITE MÉNAGÉ D'UNE CAVITÉ INTÉRIEURE AVEC UNE OUVERTURE SUR L'EXTÉRIEUR
(ES) PROCEDIMIENTO Y APARATO PARA LA FABRICACIÓN DE UN CUERPO DE MATERIAL COMPOSITE PROVISTO DE UNA CAVIDAD INTERIOR CON UNA ABERTURA AL EXTERIOR
Abstract:
(EN) A method of manufacturing a body (1) made of composite material such as a shell of a helmet. Said body (1) constitutes a multilayer structure where each layer (2, 3, 4) is formed by superposed strata comprising portions of fabrics preimpregnated with thermoplastic resin in which at least some of said layers (2, 3, 4) are formed by woven or non-woven LFRTP-type preimpregnated fabrics. The outer layer (2) is formed by strata of portions of "veil" type or "felt" type fabrics, with non-woven and non-oriented fibers of lengths comprised between 5 and 20 mm. In the method, the multilayer structure arranged in a mold is subjected to the action exerted by a bag (15) that is inflated due to pressure occupying the cavity of the mold.
(FR) La présente invention concerne un procédé de fabrication d'un corps (1) de matériau composite tel qu'une coque de casque. Ce corps (1) constitue une structure multicouche dans laquelle chaque couche (2, 3, 4) est formée par la superposition de strates qui comprennent des portions de toiles préimprégnées de résine thermoplastique parmi lesquelles au moins certaines des couches (2, 3, 4) sont formées par des toiles préimprégnées du type thermoplastique renforcé par des fibres longues (LFRTP), tissées ou non tissées. La couche extérieure (2) est formée de strates de portions de toiles du type "voile" ou du type "feutre", avec des fibres de longueurs comprises entre 5 et 20 mm non tissées et non orientées. Dans le procédé, on soumet la structure multicouche disposée dans un moule à l'action exercée par un sac (15) qui se gonfle par pression occupant la cavité du moule.
(ES) La presente invención se refiere a un procedimiento de fabricación de un cuerpo (1) de material composite tal como una calota de casco. Dicho cuerpo (1) constituye una estructura multicapa donde cada capa (2, 3, 4) se forma por la superposición de estratos que comprenden porciones de telas preimpregnadas de resina termoplástica en el que al menos algunas de dichas capas (2, 3, 4) está formada por telas preimpregnadas tipo LFRTP, tejidas o no tejidas. La capa externa (2) está formada por estratos de porciones de telas tipo "velo" o tipo "fieltro", con fibras de longitudes comprendidas entre 5 y 20 mm no tejidas y no orientadas. En el procedimiento se somete a la estructura multicapa dispuesta en un molde a la acción ejercida por una bolsa (15) que se hincha por presión ocupando la cavidad del molde.
