METHOD FOR PRODUCING HONEYCOMB SANDWICH PANEL WITH FREQUENCY SELECTION PLATE LAMINATED

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a honeycomb sandwich panel with a frequency selection plate laminated which can easily produce a large-sized fiber-reinforced plastic panel by making the laminate be impregnated with a reaction resin material.;SOLUTION: A tapered dam 12 is arranged on the side of the laminate W on a sheet 6 having rubber-like elasticity, a spiral hose 13 covered with an air weave 13a is arranged on the suction side, the whole laminate W is covered with a film-like vacuum back 9 in which a resin material charging port 7 and a suction pipe 8 connected to the hose 13 are arranged in the peripheral part, and the peripheral part is sealed on a base member 5 by an adhesive tape 10 etc. After that, the laminate W in the vacuum back 9 is vacuumed uniformly by a vacuum pump P connected to vacuum piping 8. While the inside is made a vacuum state, the room temperature curable reaction resin material Q is supplied from the resin material charging port 7 connected to a resin material supply tank 11 to the fiber-reinforced resin sheet 4 of the laminate to penetrate uniformly into the sheet 4 and cured by the reaction heat of the material Q.;COPYRIGHT: (C)2006,JPO&NCIPI
