Laminate and method for producing same

1. A method for producing a laminate including a step of laminating a resin impregnated fiber reinforced composition layer on a metal member, wherein the method includes

a step of forming a resin coating on the metal member; and

a step of laminating a resin impregnated fiber reinforced composition layer containing a resin impregnated fiber reinforced composition containing

(I) 20 to 80% by mass of a polymer having a melting point and/or a glass transition temperature of 50 to 300° C., and

(C) 20 to 80% by mass of a reinforcing fiber

(provided that the sum of the component (I) and the component (C) is taken as 100% by mass) via the above resin coating,

wherein the resin impregnated fiber reinforced composition layer is laminated by a laser fusion method,

wherein the resin coating comprises a layer containing a dye (II) which absorbs light having a wavelength of 300 to 3000 nm, and a layer which does not contain the dye (II), and

wherein the layer which does not contain the dye (II) is in contact with the metal member.

2. The method for producing a laminate according to claim 1 , wherein the resin impregnated fiber reinforced composition further contains 0.01 to 5% by mass of the dye (II) which absorbs light having a wavelength of 300 to 3000 nm (provided that the sum of the component (I) and the component (C) is taken as 100% by mass).

3. The method for producing a laminate according to claim 1 , wherein the component (I) contains a carboxylic acid group, and the content rate of structural units containing the carboxylic acid group is 0.010 to 0.045% by mass (provided that the sum of the component (I) and the component (C) is taken as 100% by mass).

4. The method for producing a laminate according to claim 1 , wherein the resin coating has a layer not containing conductive particles.

5. The method for producing a laminate according to claim 1 , wherein the resin impregnated fiber reinforced composition layer is partially laminated to the metal member via the resin coating.

6. The method for producing a laminate according to claim 5 , wherein a ratio (Xm/Xf) in the surfaces of the metal member is 5/1 to 50/1, which is the ratio of the total area (Xm) of the surface of the metal member on the side on which the resin impregnated fiber reinforced composition layer is to be partially laminated and the area (Xf) of a part on which the resin impregnated fiber reinforced composition layer is to be partially laminated.

7. The method for producing a laminate according to claim 5 , wherein a maximum width in the surfaces of the metal member is 30 to 10000 mm, which is the maximum width of the surface of the metal member on the side on which the resin impregnated fiber reinforced composition layer is to be partially laminated, and a ratio (Wf/Wm) is 0.01 to 0.5, which is the ratio of the width (Wf) of the resin impregnated fiber reinforced composition layer and the width (Wm) of the surface of the metal member.

8. The method for producing a laminate according to claim 1 , wherein the metal member is a container substrate having a curved shape.

9. The method for producing a laminate according to claim 8 , wherein the resin impregnated fiber reinforced composition layer is formed by hoop winding and/or helical winding.

10. The method for producing a laminate according to claim 1 , wherein the metal member is a metal rotor body.

11. The method for producing a laminate according to claim 10 , wherein the resin impregnated fiber reinforced composition layer is laminated at least on the outer surface of the rotation peripheral part of the metal rotor body.
