[ What is claimed is:] [1.] An inflatable tubular air beam comprising:a braided sleeve including a single structural layer of fibers;a first lengthwise curved portion including an inside lengthwise curve of said beam with the smallest radius of curvature and an outside lengthwise curve of said beam

[ What is claimed is:] [1.] An inflatable tubular air beam comprising:a braided sleeve including a single structural layer of fibers;a first lengthwise curved portion including an inside lengthwise curve of said beam with the smallest radius of curvature and an outside lengthwise curve of said beam with the largest radius of curvature, said inside curve being about 180 degrees from said outside curve about the circumference of said beam;a second lengthwise curved portion, said first lengthwise portion having a different radius of curvature than said second lengthwise curved portion; andat least one inside axial fiber being positioned along the circumference of said beam closer to said inside lengthwise curve than said outside lengthwise curve, at least one outside axial fiber being positioned along the circumference of said beam closer to said outside lengthwise curve than said inside lengthwise curve and said inside axial fiber being shorter in length than said outside axial fiber.
