Space inflatable structures are suitable for constructing lightweight and low-cost large space structures. Therefore, inflatable space structures for reflector antenna and synthetic aperture radar, which are required high surface accuracy, are also being investigated very actively This report describes application of inflatable space structures to membrane antennas. This paper examines planar membrane structures stretched by inflatable torus for membrane antenna structures Fiber reinforced plastics using tnaxial woven fabrics are used for planar membrane structures. Two types of inflatable torus and lightweight planar membrane structures are fabricated for test article Surface accuracy measurements are conducted using the test article. It is clarified that the surface accuracy of the membrane under the various pressure conditions of inflatable torus.
