The invention provides a laminated article such as door trim board capable of maintaining a bonding effect for a long period of time by integrally forming a base member and a skin member without forming the skin member in the shape of a sheet and without using an adhesive, and a manufacturing method of the laminated article by which reduction in the quantity of material to be used and simplification of manufacturing steps are achieved. A porous base member (11) molded in the shape of a door trim board and a molten resin (12melt) supplied on the surface of the porous base member are pressed between a pair of molds (31,32) so that the molten resin (12melt) is impregnated into the porous base member at least at the front surface thereof and hardened to form a skin member (12) on the porous base member (11). In the door trim board thus obtained, the resin forming the skin member (12) and the porous base member (11) are integrated by an anchor effect of resin with a reliable strength thereof retained.
La présente invention concerne un stratifié tel qu'un panneau de garnissage de porte capable de conserver ses qualités de cohésion sur une longue période par association unitaire d'un élément de base et d'un élément de finition. Selon le procédé, l'élément de finition ne se présente pas sous forme de feuille, et il n'y a besoin d'aucun adhésif pour assujettir l'élément de finition. En outre, ce procédé de fabrication permet de réduire la quantité de matériaux à utiliser et de simplifier le processus de fabrication. Le procédé consiste à mouler un élément base poreux (11) épousant la forme du panneau de garnissage de porte, à appliquer sur la surface de l'élément base poreux (11) une résine liquide (12) devant constituer l'élément de finition. La compression des deux éléments l'un contre l'autre entre deux moules (31, 32) provoque le durcissement de la résine liquide (12) qui imprègne au moins la partie visible de la façade intérieure de l'élément base poreux (11). L'effet d'ancrage assujettissant la résine constituant l'élément de finition (12) à l'élément de base poreux (11) du panneau de garnissage de porte réalisé selon le présent procédé, en garantit la résistance.
