Problems solved by technology

[0007] However, in the above-mentioned conventional composite structure, in order to manufacture an outer frame with a concave cross-section as an integral body, it is necessary to perform deep drawing of the metal plate.
In this case, since the outer frame is limited to a low-strength and stretched material, it may be difficult to apply to structures requiring specified strength such as body panels
In addition, in order to ensure the strength of the composite structure, it is also conceivable to newly install a member different from the resin member constituting the composite structure in the joining portion or branch portion of the metal member, but in this case, there is a problem of increased work steps and manufacturing costs.

[0045] Figure 1 to Figure 6 It is a figure explaining the 1st Embodiment of the composite structure of this invention. In addition, in each of the following embodiments, for the sake of convenience, the up-down, left-right, and up-down relationships of the constituent parts will be described in the postures shown in the drawings. Therefore, the up, down, left, and right relationships of the constituent parts are not limited to the postures in actual use.

[0046] figure 1 and figure 2 The shown composite structure A includes a plate-shaped first metal member M1, a plate-shaped second metal member M2, and a resin member R integrating the first and second metal members M1 and M2. The resin member R has: a first resin layer R1 covering one main surface of each of the first and second metal members M1, M2; and a first resin layer R1 covering the other of the first and second metal members M1, M2 The second resin layer R2 on the main surface.

[0065] Figure 7 and Figure 8 The shown composite structure A has a plate-shaped first metal member M1, a plate-shaped second metal member M2, and a resin member R integrating the first and second metal members M1 and M2. Moreover, in the composite structure A, the resin member R has the connection part R3 which connects the 1st resin layer R1 and the 2nd resin layer R2. In the composite structure A of this embodiment, a gap S is provided between the first and second metal members M1 , M2 , and a connecting portion R3 is formed in the gap S. As shown in FIG.

[0066] The composite structure A having the above-mentioned structure obtains the resin part R in which the first and second resin layers R1, R2 are integrated through the connection part R3, and by securing the first and second metal parts M1, M2 and the resin part R largely The contact area can further increase the strength and rigidity of the joint between the two metal parts M1 and M2.

[0075] Figure 12 The composite structure A shown is the same as the first embodiment, and one of the first and second metal members M1, M2 (the first metal member M1) has a The junction J2 of M2) is the junction J1 formed correspondingly to the shape of the end. In addition, in the first embodiment, the structure in which the end portion of the second metal member M2 is joined in the middle of the side portion Mb of the first metal member M1 has been described, but in this embodiment, the side of the first metal member M1 The end of the portion Mb engages the end of the second metal member M2.

[0076] In addition to the above-mentioned composite structure A having the same effect as the previous embodiment, the two joint parts J1, J2 are a combination of three-dimensional shapes, so the joint force can be improved, and the transmission of force can be dispersed to achieve further improvement in strength and rigidity. improve.

Abstract

Provided is a composite structure A comprising a plate-like first metal member M1, a plate-like second metal member M2, and a resin member R integrating the first and second metal members M1, M2, wherein the resin member R has a first resin layer R1 covering, across the first and second metal members M1, M2, one principal surface of each metal member, and a second resin layer R2 covering, across the first and second metal members M1, M2, the other principal surface of each metal member. The composite structure has good formability while ensuring an adequate strength, and is suitable as a component of a structure such as a vehicle body.

Description

technical field [0001] The present invention relates to a composite structure including a plurality of plate-shaped metal members and a resin member integrating the metal members, for example, to a composite structure suitable for use in structures such as vehicle bodies and a method for manufacturing the same. Background technique [0002] As a conventional composite structure, it is described in Patent Document 1 under the name of a frame side member of an automobile body structure. The composite structure described in Patent Document 1 includes a resin reinforcement structure in a space formed between a metal outer frame and a metal inner frame. [0003] The composite structure described above constitutes a side panel of an automobile. The metal outer frame is manufactured as an integral body and has a concave cross-sectional shape that is open to one side. On the other hand, the metal inner frame is preferably manufactured as a single component, and has a cross-section...
