a door internal panel;
a door external panel mounted outside a passenger compartment with respect to the door internal panel, detachably coupled to the door internal panel, and made of a material weighing less than a material of the door internal panel; and
a reinforcement member mounted between the door external panel and the door internal panel and fastened to the door external panel and the door internal panel to increase rigidity of the door,
wherein the reinforcement member is formed in a shape that corresponds to a profile of an external rim of the door external panel.

2. The door of the vehicle of claim 1 ,
wherein the material of the door external panel is plastic material, and
wherein the material of the door internal panel and a material of the reinforcement member are metal material.

3. The door of the vehicle of claim 1 ,
wherein a door trim is coupled to the door internal panel.

4. The door of the vehicle of claim 1 ,
wherein an impact beam is coupled to the door internal panel between the door internal panel and the door external panel.

5. The door of the vehicle of claim 1 ,
wherein an opening is formed at a center portion of the door internal panel.

6. The door of the vehicle of claim 1 ,
wherein an opening is formed at a center portion of the reinforcement member.

7. A door of a vehicle, the door comprising:
a door internal panel;
a door external panel mounted outside a passenger compartment with respect to the door internal panel, detachably coupled to the door internal panel, and made of a material weighing less than a material of the door internal panel; and
a reinforcement member mounted between the door external panel and the door internal panel and fastened to the door external panel and the door internal panel to increase rigidity of the door,
wherein the door external panel is provided with a fastening member having a first assembly hole;
wherein the reinforcement member is provided with a second assembly hole corresponding to the first assembly hole of the fastening member; and
wherein a fastener is inserted into the first assembly hole of the fastening member and the second assembly hole of the reinforcement member to be fastened to the fastening member and the reinforcement member.

8. The door of the vehicle of claim of claim 7 , wherein the fastening member is disposed between the door external panel and the reinforcement member.

9. The door of the vehicle of claim of claim 7 ,
wherein the fastening member is formed at an inside surface of the door external panel facing the internal to the passenger compartment to protrude toward the reinforcement member.

10. The door of the vehicle of claim of claim 7 ,
wherein an end portion of the fastener is enclosed inside the door internal panel.

11. The door of the vehicle of claim 7 ,
wherein the door internal panel and the reinforcement member are coupled to each other through a hamming.

12. The door of the vehicle of claim 11 ,
wherein the door external panel is provided with a finishing flange covering the hamming of the door internal panel and the reinforcement member.

13. The door of the vehicle of claim 7 ,
wherein the material of the door external panel is plastic material, and
