Description of the Related Art One of the manufacturing methods for molding a resin molded product by injecting a resin into a mold is a method called resin transfer molding (hereinafter referred to as RTM). This R
In TM, FRP products such as automobile outer panels are formed using a thermosetting resin and a glass fiber mat. When two or more such thermosetting resin parts are bonded, a two-pack type slow drying adhesive is generally used. This is because if a quick-drying adhesive (generally a one-pack type) is used, sinks are generated on the surface of the product and stress concentration is likely to occur, so that an adhesive that cures slowly is used. Japanese Patent Application Laid-Open No. 63-132788 discloses a method in which a thermosetting resin is filled between two folded and superposed plates, and the thermosetting resin is cured by applying ultrasonic vibration while applying pressure. Describes a method of joining two plates at a bent portion. Also, Japanese Patent Application Laid-Open No. 61-277427
In the publication, a dovetail recess is formed in a thermosetting resin part,
A method is described in which a convex portion is formed on a thermoplastic resin component, a medium material is inserted into the dovetail-shaped concave portion, and the thermosetting resin component and the thermoplastic resin component are joined. [0004] In the case of using a conventional two-part adhesive of a slow curing type, it is necessary to fix a joint part with a jig until the adhesive is cured. Since the bonding time using the jig is long, a large number of jigs are required in the production process. To reduce the curing time of the adhesive by heating in order to improve this, a special heating jig is required, and equipment investment becomes large. The bonding method described in the above-mentioned Japanese Patent Application Laid-Open No. 63-132788 involves filling a thermosetting resin between two folded and superposed plates and curing the same. Are weak in bonding strength, and in the case of butt bonding, a sufficient bonding strength cannot be obtained. In addition, Japanese Patent Application Laid-Open No. 61-27
The joining method described in Japanese Patent No. 7427 relates to joining between a thermosetting resin component and a thermoplastic resin component, and cannot be applied to joining between thermosetting resin components. An object of the present invention is to provide a method for bonding thermosetting resin parts to each other without using a heating type bonding jig, shortening the use time of a bonding jig, and reducing capital investment. It is intended for. According to the present invention, a thermoplastic resin piece having an abutting portion is provided on each of the bonding surfaces of a thermosetting resin component, and two liquids are placed on the bonding surface. A mold adhesive is applied and the thermoplastic resin pieces are abutted against each other and positioned and fixed with a jig.Then, the abutted portions of the thermoplastic resin pieces are welded, and then the thermosetting resin part is removed from the jig. This is a method of bonding a thermosetting resin component in which the adhesive is cured by heating. The abutting portion of the thermoplastic resin piece on the bonding surface of the thermosetting resin component is welded in a very short time, and the thermosetting resin components are temporarily fixed to each other. And slowly cure the adhesive. 1 and 2 are a cross-sectional view and a perspective view for explaining a bonding method according to the present invention. FIG. 1 shows a bonding state, and FIG. 2 shows a state before bonding. As shown in the figure, a thermoplastic resin piece 2 is previously installed in place on each of the bonding surfaces of the thermosetting resin parts 1 and 1, and a protrusion 3 is formed on each thermoplastic resin piece 2. When joining the resin parts 1 and 1, the projections 3 are brought into contact with each other. When the thermosetting resin part 1 is formed by RTM, the thermoplastic resin piece 2 is integrally and firmly attached by inserting the bulging portion 4 into the thermosetting resin. The two-component adhesive 5 is applied to the bonding surfaces of the thermosetting resin parts 1 and 1, and is positioned and fixed by a jig (not shown), and is maintained in the state shown in FIG. The adhesive 5 on the joining surface has a uniform thickness defined by the height of the protrusion 3 of the thermoplastic resin piece 2. Ultrasonic waves are applied to the joints between the thermosetting resin parts 1 and 1 to weld the butting portions of the thermoplastic resin pieces 2 between the projections 3. For example, if the thermoplastic resin piece 2 is made of polypropylene (PP), it will be welded in a few seconds. Heat welding may be used instead of welding by ultrasonic vibration. Since the thermosetting resin parts 1 and 1 are temporarily fixed by welding the protrusions 3 of the thermoplastic resin piece 2, the thermosetting resin parts 1 and 1 are removed from the jig and the adhesive 5 is naturally cured. Heat may be applied to shorten the curing time of the adhesive 5. In the above-described embodiment, the thermoplastic resin pieces 2 are installed at various places of the thermosetting resin parts 1 and 1.
This is because if the thermoplastic resin piece 2 is provided over the entire joint, when the product after bonding is heated, the difference in the number of linear expansion systems between the thermosetting resin and the thermoplastic resin is large, and the product is warped or deformed. This is to prevent occurrence. According to the present invention, the thermosetting resin parts need only be held by a jig until they are temporarily fixed to each other by welding of the thermoplastic resin parts. Even if an adhesive having a low speed is used, the use of a jig can be performed in an extremely short time, and equipment investment can be reduced. Further, there is no possibility that the bonded product is warped or deformed.
