Abstract

Un método de fabricación de panel rigidizados hechos a partir de material compuesto que comprende un panel de revestimiento y uno o más larguerillos aplicados rígidamente a la cara del panel, comprendiendo el método las siguientes etapas: a1) proporcionar al menos un larguerillo (16) de material compuesto termoendurecible polimerizable reforzado con vidrio, que tiene una sección transversal con forma de W con una parte de forma cerrada o cóncava, rectilínea o curvilínea, y dos cordones laterales opuestos (16a); a2) proporcionar un panel o capa de revestimiento (14) de material compuesto termoendurecible polimerizado o polimerizable reforzado con vidrio; b) situar un primer de dichos dos elementos de material compuesto (14 o 16) sobre una superficie de una herramienta de conformado rígida (15) congruente con una superficie de dicho primer elemento; c) situar, sobre el primer elemento de material compuesto (14 o 16), un elemento de soporte alargado (10) que soporta una bolsa de película (11), y una capa de respiración (12) alrededor de la misma, todo sellado por una película de separación tubular (13); d1) dejar el segundo elemento compuesto (16 o 14) sobre el soporte alargado (10) poniendo los cordones laterales (16a) del larguerillo en contacto con el panel de revestimiento, con el fin de definir una cavidad de sección transversal predeterminada entre estos dos elementos compuestos; 2) proporcionar una placa de prensado (17) que tiene un perfil congruente con el perfil externo del segundo elemento; d3) dejar la placa de prensado (17) sobre el segundo elemento (16 o 14); e) cubrir la placa de prensado (17) con una bolsa de película externa (18) sellándola tanto a la herramienta de conformado (15) como en los extremos opuestos abiertos de la bolsa interna (11), con el fin de formar una envoltura de película que rodea el exterior de la placa de prensado y que internamente está estrechamente envuelta alrededor del soporte interno (10); f) aplicar vacío a dicha envoltura de película con el fin de aplicar una presión uniforme al material compuesto, del que la parte inferior descansa sobre la herramienta rígida (15), mientras que su parte superior está comprimida entre la bolsa externa (18) y la bolsa interna tubular (11) y está estabilizada a través de la placa de prensado (17), transmitiéndose la presión al material compuesto sin la interposición de mandriles intermedios; y g) curar en una autoclave por medio de un ciclo de aplicación de temperatura y presión programado.
