Abstract:
A closure panel assembly includes an inner and an outer panel, the inner panel having a crimped edge surface feature and a textured surface feature such as a set of radial projections or asperities. Adhesive material is applied between the panels, and the outer panel is hemmed and adhesively bonded to the inner panel. The surface features affix the panels together without induction or intermediate heat curing of the adhesive material. The outer panel has a hemmed edge enclosing the crimped surface feature, with the adhesive material positioned therebetween to form a seal of a relatively low shrinkage rate. A method of forming the closure panel assembly includes forming a first and second surface feature on the inner panel, such as by using swaging and coining, respectively, applying adhesive material therebetween, and hemming the panels to form a hem seam.
