ABSTRACT:
A self-deploying structural element formed of a core of temperature sensitive expanding foam, a load carrying component of advanced composite material, and an outer retaining jacket. A heat generating means such as resistance heating wires is included to initiate deployment of the structure. The heating of the structure causes the foam core to expand, unrolling or unfolding the structure. The heat also cures the advanced composite material to a rigid form. The retaining jacket is preferably a heat shrink jacket which contracts around the composite material.
