Abstract

Provided is a composite material of a fiber reinforced plastic and a rubber material in which peeling between the fiber reinforced plastic and the rubber material is prevented. A composite material, including: a first member containing a fiber reinforced plastic; and a second member containing a rubber material and formed to be in direct contact with the first member within at least a part of a region on the first member, wherein the first member and the second member are integrated.

Claims (26)

1 . A composite material, comprising:

a first member containing a fiber reinforced plastic; and

a second member containing a rubber material and formed to be in direct contact with the first member within at least a part of a region on the first member,

wherein the first member and the second member are integrated.

2 . The composite material according to claim 1 , wherein the first member and the second member are in direct contact, and an adhesive member is not interposed between the first member and the second member.

3 . The composite material according to claim 1 , wherein the first member and the second member are sheet-like, and the composite material has a laminate structure.

4 . The composite material according to claim 2 , wherein the first member and the second member are sheet-like, and the composite material has a laminate structure.

5 . The composite material according to claim 1 , wherein the rubber material is at least one selected from the group consisting of nitrile rubber, fluorine rubber, butyl rubber, ethylene-propylene-diene rubber, hydrogenated nitrile rubber, and silicone rubber.

6 . The composite material according to claim 2 , wherein the rubber material is at least one selected from the group consisting of nitrile rubber, fluorine rubber, butyl rubber, ethylene-propylene-diene rubber, hydrogenated nitrile rubber, and silicone rubber.

7 . The composite material according to claim 1 , wherein the rubber material is at least one selected from the group consisting of nitrile rubber, fluorine rubber, and butyl rubber.

8 . The composite material according to claim 2 , wherein the rubber material is at least one selected from the group consisting of nitrile rubber, fluorine rubber, and butyl rubber.

9 . The composite material according to claim 1 , wherein the fiber reinforced plastic is a carbon-fiber reinforced plastic.

10 . The composite material according to claim 2 , wherein the fiber reinforced plastic is a carbon-fiber reinforced plastic.

11 . The composite material according to claim 1 , wherein the first member is a multilayer structure having: a first one of the fiber reinforced plastic that forms a first layer in which a fiber orientation angle is a first direction; and a second one of the fiber reinforced plastic that forms a second layer in which a fiber orientation angle is a second direction different from the first direction.

12 . The composite material according to claim 2 , wherein the first member is a multilayer structure having: a first one of the fiber reinforced plastic that forms a first layer in which a fiber orientation angle is a first direction; and a second one of the fiber reinforced plastic that forms a second layer in which a fiber orientation angle is a second direction different from the first direction.

13 . The composite material according to claim 1 , wherein an outer surface of the composite material is of the first member.

14 . The composite material according to claim 2 , wherein an outer surface of the composite material is of the first member.

15 . The composite material according to claim 1 , wherein an outer surface of the composite material is of the second member.

16 . The composite material according to claim 2 , wherein an outer surface of the composite material is of the second member.

17 . The composite material according to claim 1 , wherein the composite material is formed in a plate shape or a cylindrical shape.

18 . The composite material according to claim 2 , wherein the composite material is formed in a plate shape or a cylindrical shape.

19 . A method for manufacturing a composite material, the method comprising:

a step of providing a first precursor being an uncured or semi-cured material in which a fiber is impregnated with a resin;

a step of directly laminating a second precursor containing an unvulcanized rubber onto at least a part of a region on the provided first precursor to obtain a laminate of the first precursor and the second precursor; and

an integrating step of heat-treating the obtained laminate to obtain a first member containing a fiber reinforced plastic by thermally curing the resin of the first precursor and obtain a second member containing a rubber material by vulcanizing the unvulcanized rubber of the second precursor, and integrating the first member and the second member.

20 . The method for manufacturing a composite material according to claim 19 , wherein the second precursor containing an unvulcanized rubber blended with a vulcanizer is directly laminated onto the provided first precursor without interposing an adhesive member.
