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.

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.
