Abstract
A boom structure deployed by inflating the structure to a desired shape and rigidizing the structure via an external influence. The structure frame has a series of frame members which are made of a fibrous material and a resin material. This frame is encased in between a pair of membrane layers, an inner membrane inflatable to move the frame into its desired shape and an outer membrane that allows for folding the structure. Following inflation of the inner layer, an external influence acts on the resin material to solidify it, and render the structure rigid. The external influence may also act on the resin material to soften it when it is already rigid, to allow for collapsing and folding of the structure.
