ABSTRACT:
The joint reinforcement member for a hollow structure of an automotive vehicle has a carrier portion with an outer surface. The carrier portion has a base portion with a first extension having a first longitudinal axis and a second extension having a second longitudinal axis. The first longitudinal axis and second longitudinal axis correspond to the hollow structure. A thermally expandable adhesive layer is disposed on the outer surface of the carrier portion and substantially covers the outer surface. A method for forming the joint member includes providing a carrier having a plurality extensions extending from a base portion that correspond to the hollow structure a layer of thermally expandable adhesive materials applied to the carrier portion. The carrier portion is heated to activate the adhesive layer. The adhesive layer is cooled so that the adhesive layer is bonded to the structural member. The reinforcement member may be inserted into the hollow structure of an automotive vehicle before assembly of the vehicle so that during a paint bake operation, the adhesive portion is heated and bonded to the structure of the vehicle.
