Abstract
A stiffener is provided for reinforcing a hollow structure having a pair of spaced walls with a pin extending across the walls. The stiffener includes a carrier member with a layer of expandable polymer which creates a structural foam when the polymer is later expanded. The stiffener could comprise a horseshoe shaped laminate shaped to fit over the pin of the hollow structure so that when the polymer is expanded it forms a structural foam intimately bonded to the pair of spaced walls.
