Deployable structures usign bi-stable reeled composites

摘要

This paper describes an innvative, patented use of composite materials developed yb RolaTube Technology Ltd. to make smart deployable structures. bi-stable reeled composites 9BRCs0 can alternate between two stable forms; that of a strong, rigid structure and that of a compact coil of flat-wound material. Bi-stability arises as a result of the manipulation of Poisson's ratio and isotropy in the various layers of the material. BRCs are made of fiber-reinforced composite materials, most often with a thermoplastic matrix. A range of fibers and polymer matrices can be used according to the requirements of the operating environment.
