ABSTRACT:
A stiffener is provided for reinforcing a hollow structure having a pair of spaced 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 single laminate shaped to fit in the appropriate locations of the hollow structure so that when the polymer is expanded it forms a structural foam intimately bonded to the pair of spaced walls. The stiffener may also be in the form of a corrugated frame wherein individual laminates are provided with notches to permit the individual laminates to be interlocked with each other at the notches.
