Title (EN) METHOD OF CURING A POLYMERIC FORM AND CURING DEVICE FOR POLYMERIC MATERIALS USING THERMAL EXPANSION
(FR) PROCÉDÉ DE DURCISSEMENT D'UNE FORME POLYMÈRE ET DISPOSITIF DE DURCISSEMENT DE MATÉRIAUX POLYMÈRES FAISANT APPEL À LA DILATATION THERMIQUE
Abstract: front page image
(EN)The present invention is related to a method and an apparatus for curing a polymeric form. The method includes arranging an uncured polymeric form within a curing chamber (60) formed by a base member (20) and a constraining member (40). A thermal expansion member (30) is additionally positioned within the curing chamber (60) with the uncured polymeric form (70) such that the thermal expansion member and the uncured polymeric form are positioned between the base member (20) and the constraining member (40). The thermal expansion member (30) is heated to expand in size into an expanded state. In the expanded state the thermal expansion member (30) applies pressure to the uncured polymeric form (70) within the curing chamber. The expansion of the thermal expansion member (30) is maintained to maintain the application of pressure to the uncured polymeric form while the uncured polymeric form is being cured to form a cured polymeric form.
(FR)La présente invention porte sur un procédé et un appareil de durcissement d'une forme polymère. Le procédé consiste à disposer une forme polymère non durcie à l'intérieur d'une chambre de durcissement (60) constituée d'un élément de base (20) et d'un élément de contrainte (40). Un élément de dilatation thermique (30) est en outre positionné à l'intérieur de la chambre de durcissement (60) avec la forme polymère non durcie (70), de telle sorte que l'élément de dilatation thermique et la forme polymère non durcie sont positionnés entre l'élément de base (20) et l'élément de contrainte (40). L'élément de dilatation thermique (30) est chauffé pour se dilater en taille jusqu'à un état dilaté. À l'état dilaté, l'élément de dilatation thermique (30) applique une pression sur la forme polymère non durcie (70) à l'intérieur de la chambre de durcissement. La dilatation de l'élément de dilatation thermique (30) est maintenue afin de maintenir l'application d'une pression sur la forme polymère non durcie tandis que la forme polymère non durcie est durcie, afin de former une forme polymère durcie.
