Problems solved by technology

First, when painting, bending, etc., existing equipment such as painting pipelines installed on metal members such as steel and bending molds cannot be directly used for FRP.
Second, due to the low compressive strength of FRP, it is difficult to directly use it in automotive components that require high compressive strength
Third, the matrix resin of FRP is generally a thermosetting resin such as epoxy resin, so it is brittle, and there is a possibility of brittle fracture if deformed
Fourth, because of the high price of FRP (in particular, Carbon Fiber Reinforced Plastics (CFRP: Carbon Fiber Reinforced Plastics) in which carbon fibers are used as reinforcing fibers), it becomes a factor that increases the cost of automobile components
Fifth, as mentioned above, since thermosetting resin is used as the matrix resin, it takes a long time to harden and the takt time is long, so it is not suitable for the manufacture of automobile components that require a short takt time.

[0060] [Constitution of Metal-Fiber Reinforced Resin Composite]

[0061] First, refer to figure 1 and figure 2 , the configuration of the metal-fiber-reinforced resin material composite according to the first embodiment of the present invention will be described. figure 1 and figure 2 It is a schematic diagram showing a cross-sectional structure in a lamination direction of a metal-FRP composite 1 as an example of a metal-fiber-reinforced resin composite according to the present embodiment.

[0062] Such as figure 1 As shown, the metal-FRP composite 1 includes a metal member 11 , an FRP layer 12 as an example of the first fiber-reinforced resin material according to the present embodiment, and an adhesive resin layer 13 . Metal member 11 and FRP layer 12 are composited via adhesive resin layer 13 . Here, "composite" means that the metal member 11 and the FRP layer 12 (first fiber-reinforced resin material) are bonded (bonded) via the adhesive resin layer 13 to be integr...

[0180] [Constitution of Metal-Fiber Reinforced Resin Composite]

[0181] Next, refer to Figure 7 and Figure 8 , the configuration of the metal-fiber-reinforced resin material composite according to the second embodiment of the present invention will be described. Figure 7 and Figure 8 It is a schematic diagram showing a cross-sectional structure in the lamination direction of a metal-FRP composite 2 as an example of a metal-fiber-reinforced resin composite according to the present embodiment.

[0182] Such as Figure 7 As shown, the metal-FRP composite 2 includes a metal member 11 , an FRP layer 12 as an example of the first fiber-reinforced resin material according to the present embodiment, and an adhesive resin layer 13A. Metal member 11 and FRP layer 12 are composited via adhesive resin layer 13A. In the present embodiment, the adhesive resin layer 13A is a second fiber-reinforced resin material having a matrix resin 103 and a reinforcing fiber material 104 contai...

Embodiment 1

[0316] M-1 fully degreased with acetone was used as the metal member 11, the phenoxy resin CFRP prepreg A of Production Example 1 was used as the FRP layer 12, and the phenoxy resin film of Production Example 7 was used as the adhesive resin Layer 13, will Figure 10A sample of the metal-CFRP composite for the tensile test of the structure shown was produced by pressing at 3 MPa for 3 minutes with a press machine heated to 250°C. The thickness of the adhesive resin layer 13 was 20 μm. The obtained samples were subjected to a tensile test after cooling. The results are shown in Table 1.

[0317] In addition, as for the metal member (M-1), there is no adhesion of anti-rust oil on the surface, and it is a steel plate with high adhesion. Therefore, even if the same test is carried out without degreasing, the super-mixing law is also expressed, and the obtained and carried out Same results as in the case of degreasing Example 1.

Abstract

[Problem] To provide a metal / fiber-reinforced resin material composite in which a metal member and a fiber-reinforced resin material are firmly bonded, a light weight and excellent workability are obtained while the strength is enhanced, and the amount of the fiber-reinforced resin material used can be reduced. [Solution] A metal / fiber-reinforced resin material composite comprising a metal member,and a first fiber-reinforced resin material having a matrix resin and a reinforcement fiber material, the metal member and the first fiber-reinforced resin material being formed into a composite withan adhesive resin layer interposed therebetween, wherein the adhesive resin layer is obtained by solidifying or curing an adhesive resin composition containing at least 50 mass parts of a phenoxy resin (A), and the maximum load of the metal / fiber-reinforced resin material composite is greater than the total load of the maximum load of the metal member alone and the maximum load of the fiber-reinforced resin material alone (i.e., so as to display a law of over-mixture that surpasses the law of mixture with respect to the tensile load).

Description

technical field [0001] The present invention relates to a metal-fiber-reinforced resin material composite in which a metal member and a fiber-reinforced resin material are laminated and integrated. Background technique [0002] Fiber Reinforced Plastics (FRP: Fiber Reinforced Plastics), which are composited by including reinforcing fibers (for example, glass fibers, carbon fibers, etc.) in a matrix resin, are lightweight and excellent in tensile strength, processability, and the like. Therefore, it is widely used from the field of people's livelihood to industrial use. In the automotive industry, the need for lightweight car bodies related to improvements in fuel consumption and other performance is also met. Therefore, the application of FRP to automotive components has been studied focusing on the lightweight properties, tensile strength, and processability of FRP. [0003] When FRP itself is used as an automobile component, there are various problems as follows, for exam...
