Outline of Final Research Achievements

Several initiatives were implemented on the storage technology of the membrane surface of the curved surface shape proposed by the applicant. (1) We examined the use and storage method as antenna for parabolic shape. (2) Utilizing the characteristics of handling the film thickness as variable, we realized the storage technology considering the existence of the parts on the surface. In addition, the panel shape can be accommodated by considering the thickness. We developed a new method to apply the Miura folding technique to the plate structure. (3) The development behavior of the stored membrane surface was realized considering a mechanical properties as a numerical simulation. (4) A storage technique combining spiral folding and bellows folding was mathematically formulated with respect to the plane surface and curved surface, and verified by experiment. (5) As a new use, application to adhesive plaster, air bag, etc. was studied.
