Manufacturing method of joint panel

Abstract

A manufacturing method of a joint panel includes: joining an outer panel to an inner panel by applying an adhesive to an outer edge of the outer panel; performing electrodeposition coating on a surface of the outer panel of the joint panel in which the outer panel is joined to the inner panel; and burning, onto the outer panel, a coating film formed on the surface of the outer panel by the electrodeposition coating. The adhesive used herein is a room temperature curing adhesive that does not flow at the time of the burning.

What is claimed is: 
     
         1 . A manufacturing method of a joint panel, comprising:
 joining an outer panel made of a metallic material to an inner panel made of a material having a linear expansion coefficient different from a linear expansion coefficient of the metallic material by applying an adhesive to an outer edge of an outer edge of the outer panel and an outer edge of the inner panel and curing the adhesive;   performing electrodeposition coating on a surface of the outer panel of the joint panel in which the outer panel is joined to the inner panel; and   burning, onto the outer panel, a coating film formed on the surface of the outer panel by the electrodeposition coating, wherein   the adhesive is a room temperature curing adhesive that does not flow at the time of the burning.   
     
     
         2 . The manufacturing method of the joint panel, according to  claim 1 , wherein:
 the metallic material of the outer panel is aluminum alloy; and   the material of the inner panel is a fiber reinforced plastic.   
     
     
         3 . The manufacturing method of the joint panel, according to  claim 1 , wherein:
 at the time of the joining, a hemming process is performed such that the adhesive is applied to the outer edge of the outer panel, and the outer edge of the outer panel is folded toward the outer edge of the inner panel.   
     
     
         4 . The manufacturing method of the joint panel, according to  claim 1 , wherein the adhesive is a two-component epoxy adhesive.
