A curved, inflated, tubular beam consists of braided fibers and axial fibers on an elastomeric barrier. The construction can be accomplished on a short, straight mandrel. The curvature along the beam can be varied to suit the design needs. The angle of the braid in the bias fibers determines the inflated curvature when axial fibers situated within the braid along the inside of the curvature constrain the elongation on the inside of the curvature. The curved shape can be reinforced by having tape cemented to the outside of the inflated tube. While very small and very large tubes can be perfected for a range of inflation pressures and beam strengths, the preferred embodiment is a 12 ¾-inch diameter tube, 60 feet long forming an arch for a tent 30 feet wide and 24 feet high.

A curved, inflated, tubular beam of a given length, diameter and radii of curvature, the curvature being contained within a plane, comprising: an elastomeric, gas-containable tube extending the length of the beam, the tube having means for the introduction of and holding of gas at a pressure elevated above the surrounding pressure, the tube surrounded by two sets of reinforcing fibers, one set of the fibers being an interlaced pattern of crossing strands, individual strands forming a helix, the helix angle being variable along the tube, the other set of fibers, an axial set, extending among the first set and extending parallel to the axis of the tube, the axial set extending as multiple fibers forming a width of fibers, the width extending partially around the circumference of the tube symmetrically on either side of the intersection of a plane through the tube, the plane being within the plane of curvature, the axial fibers extending the full length of the tube, the axial fibers being centered around the center of an area of the surface of the tube, the area being on the inside of the curvature of the tube, mean for sealing the ends of the tube and for valving the inflation gas.
