Embodiment 1

[0104] Figure 8 A schematic diagram schematically showing the dimensions of the strip-shaped test piece produced in this example is shown. Figure 8 In , the size of the strip test piece is exaggerated and does not reflect the exact value.

[0105] in order to make a Figure 8 A strip-shaped test piece of such a size is schematically shown in , and as the metal layer 11, a 0.40 mm thick steel plate (GA steel plate manufactured by Nippon Steel Co., Ltd.) was prepared, and as the FRP layer 13, a 1.00 mm thick CFRP ( Manufactured by Nittetsu Chemical & Material Co., Ltd.: Cloth material (Vf60) using a phenoxy resin as a matrix resin. In addition, as the resin layer 12 , a layer formed of a polyurea resin (manufactured by Nittetsu Chemical & Material Co., Ltd.: Polyurea Putty FU-Z) having a thickness of 0.50 mm was prepared. The elastic modulus of the resin layer was 50 MPa when the dynamic viscoelasticity measurement of the resin layer was carried out under the above conditio...

Embodiment 2

[0113] A strip-shaped test piece was produced in the same manner as in Example 1 except that the thickness of the CFRP used was 0.50 mm. After exposing the obtained strip test piece in the same manner as in Example 1, it evaluated in the same manner as in Example 1.

Embodiment 3

[0115] For the same 0.40 mm thick steel plate as in Example 1, a room temperature curing adhesive (Super XG manufactured by Cemedine Co., Ltd.) was applied so that the thickness after curing was 0.50 mm, and the same as in Example 1 was 1.00 mm thick CFRP fit. The obtained laminate was held at room temperature for 12 hours to cure the room temperature curing adhesive, thereby producing a strip-shaped test piece with a three-layer structure. For the room temperature curing adhesive used, the elastic modulus obtained from the dynamic viscoelasticity measurement result is 10 MPa as described above, so the layer formed by the above room temperature curing adhesive satisfies both the function as a resin layer and the bonding function. By. The obtained strip test piece was evaluated in the same manner as in Example 1.

Abstract

[Problem] To provide a metal-fiber-reinforced resin (FRP) composite which has a good appearance even when used as an automobile outer panel, and which does not deform even after a coating and sintering step. [Solution] This metal-FRP composite has a laminated structure of three or more layers, and the laminated structure of three or more layers is provided with at least: a metal layer; a fiber-reinforced resin material layer in which a reinforcing fiber material is held in a layer comprising a matrix resin; and a resin layer positioned between the metal layer and the fiber-reinforced resin material layer, the resin layer being a layer composed of a normal-temperature-curable adhesive or a layer composed of a predetermined resin and a normal-temperature-curable adhesive, the elastic modulus (E) of the resin layer being more than 0.1 MPa and 1,000 MPa or less. The thickness of the resin layer is at least 0.005 times and less than 7.500 times the thickness of the metal layer.

Description

technical field [0001] The present invention relates to metal-fiber reinforced resin material composites. Background technique [0002] In order to meet the needs of lightweight vehicles and the improvement of safety, the development of automotive materials composed of metal materials and carbon fiber reinforced plastic (Carbon Fiber Reinforced Plastic: CFRP) is carried out. In the case of using CFRP alone as an automobile component, there are problems in using existing automobile manufacturing equipment for metal components, and there are problems in CFRP processability, compressive strength, brittleness, cost, and the like. Therefore, it is expected to solve these problems by combining metal members and CFRP, and most of them have a structure in which a metal plate and CFRP are bonded together. The combination of the above-mentioned metal member and CFRP enables the development of excellent materials that cannot be achieved by each of the metal member and CFRP alone. [...
