Abstract
Reinforcement devices (10, 10', 110, 110') may be inserted into a cavity (6) of a hollow structural member (1) in order to reinforce the hollow structural member (1). The reinforcement devices (10, 10', 110, 110') may include a first elongated reinforcement part (11, 111) having at least one mating surface (15a, 17a, 115a) extending along a longitudinal axis of the first part (11, 111) and a second elongated reinforcement part (12, 121) having at least one mating surface (25a, 27a, 125a) extending along a longitudinal axis of the second part (12, 121). An adhesive resin material preferably adheres the first elongated reinforcement part (11, 111) to the second elongated reinforcement part (12, 121). The adhesive resin material may comprise a thermosetting resin that thermosets when heated. Thus, a thermoset product (31, 136) will connect the reinforcement parts (11, 12, 111, 121) after heating. In addition or in the alternative, the adhesive resin material may comprise a foamable resin that foams when heated. Thus, a foamed product (31, 136) will connect the reinforcement parts (11, 12, 111, 121) after heating.
