ABSTRACT:
An air beam made up of a cylindrical braid and lined with a gas-retaining bladder is improved in its resistance to wrinkling or buckling by incorporating linear bundles of fibers extending parallel to the axis of the cylindrical braid within the cylindrical weave and spaced around the circumference of the cylindrical weave. Another implementation is used when the required strength of the axial bundles implies that they will not fit within the braid, in which case, the bundles are made up into external straps retention means is a coating applied to the braided fibers.
