Abstract
(EN)
A curing apparatus and a curing method for a composite material. The apparatus comprises an electric heating element (222), a vibrating mesa (7), a microwave generator (1), a microwave cavity (2), a microwave local shielding element (3), and a vacuuming part. The vibrating mesa (7) used for placing the composite material is provided within in the microwave cavity (2). The microwave generator (1) and the electrical heating element (222) are used for heating the composite material. The microwave local shielding element (3) is arranged within the microwave cavity (2). The vibrating mesa (7) is a vibrating mesa capable of providing the composite material with vibrations of which the vibration frequency is 5,000 Hz or less and vibrations of which the vibration acceleration is 2 g or more. The microwave generator (1) and the microwave local shielding element (3) allow the apparatus to perform spot or directional heating of the composite material. The electrical heating element (222) allows the apparatus to perform overall heating of the composite material. The vibrating mesa (7) provides a vibration acceleration of 2 g or more in the vertical direction for the curing of the composite material. The apparatus and method allow the composite material to be cured in atmospheric pressure to produce a workpiece having great performance.

L'invention concerne un appareil et un procédé de durcissement pour un matériau composite. L'appareil comprend un élément chauffant électrique (222), un plateau vibrant (7), un générateur de micro-ondes (1), une cavité micro-ondes (2), un élément de blindage local contre les micro-ondes (3), et une partie de mise sous vide. Le plateau vibrant (7) utilisé pour placer le matériau composite est disposé à l'intérieur de la cavité micro-ondes (2). Le générateur de micro-ondes (1) et l'élément chauffant électrique (222) sont utilisés pour chauffer le matériau composite. L'élément de blindage local contre les micro-ondes (3) est disposé dans la cavité micro-ondes (2). Le plateau vibrant (7) est un plateau vibrant permettant de disposer le matériau composite et générant des vibrations dont la fréquence est de 5000 Hz ou moins et des vibrations dont l'accélération est de 2 g ou plus. Le générateur de micro-ondes (1) et l'élément de blindage local contre les micro-ondes (3) permettent à l'appareil d'effectuer un chauffage par points ou directionnel du matériau composite. L'élément chauffant électrique (222) permet à l'appareil d'effectuer un chauffage global du matériau composite. Le plateau vibrant (7) génère une accélération des vibrations de 2 g ou plus dans la direction verticale pour le durcissement du matériau composite. L'appareil et le procédé permettent de durcir le matériau composite à la pression atmosphérique pour produire une pièce ayant une grande performance.
