Abstract

PURPOSE:To enable to make the joined part homogeneous with and similar shape as the other portion of a resin board and, in addition, to mechanize the joining and at the same time to fully impregnate and deaerate by internally pressurizing by a method wherein the joining of skins is done by molding a joint with resin supplied to a portion at which exposed reinforcing fibers are intertwined with each other. CONSTITUTION:Firstly, a back-up device 40 is arranged through suction cups 41 between the undersides of skins 34 so as to elastically abut the sealing rubber plate 48 of a back-up plate 46 through springs 46 between and against the undersides of the skins 34 across a fiber-intertwined portion 37. Under the above-mentioned state, the supply of resin 38 and the application of a press roll 51 are repeated from above to the fiber intertwined portion 37 so as to impregnate the resin 38 through pressurization and deaeration. Secondly, a hold-down device 52 is arranged through suction between the top surfaces of both the skins 34. The interiors of both hollow parts 49 and 61 are pressurized so as to expand the sealing rubber plates 48 and 60 of the back-up plate 45 and of a hold-down plate 56 in the opposite directions in order to pinchingly press the resin 38 supplied to the fiber-intertwined portion 37 and to accelerate the impregnation and deaeration of the resin. Finally, the resin 38 is cured so as to obtain a shell 39 by molding.

らませている。Elaborate Means to Solve the Problems In order to solve the above-mentioned problems, the method of connecting fiber-reinforced resin plates in the present invention is achieved by curing the resin impregnated with the reinforcing fibers. To join a pair of exposed resin plates, first, the exposed reinforcing fibers are entangled with each other, and then placed between the lower surfaces of both resin plates by adsorption, and then the receiving plate of the receiving device is attached to the entangled portion. The lower surfaces of the resin plates are brought into elastic contact with each other, and in this state, the resin is supplied from above to the entangled portion while pressurizing and defoaming, and then a holding device is placed between the upper surfaces of both the resin plates. Then, the holding plate of the holding device is brought into elastic contact between the upper surfaces of the resin plates across the entangling portion, and then at least one of the receiving plate and the holding plate is pressed by internal pressure. It's inflated.

化樹脂板の連結方法。1. To join a pair of resin plates obtained by curing resin impregnated with reinforcing fibers and with the reinforcing fibers exposed at the ends, first entangle the exposed reinforcing fibers together, and then tighten the bottom surfaces of both resin plates. A receiving device is placed in between by suction, and the receiving plate of the receiving device is brought into elastic contact between the lower surfaces of the resin plates across the entangled portion, and in this state, resin is applied to the entangled portion from above. Pressure degassing is performed while supplying the resin, and then a holding device is adsorbed between the upper surfaces of both resin plates, and the holding plate of the holding device is elastically brought into contact between the upper surfaces of the resin plates across the entangled portion. A method for connecting fiber-reinforced resin plates, in which at least one of the receiving plate and the holding plate is inflated by internal pressure.
