Abstract: A device can be configured as an under-constrained deployable system. Such a system can use under-constrained deployable couplers. A device may include a second segment coupled to the first segment by a high strain structure, wherein the high strain structure is bent to store deployment energy in a stowed configuration. Releasing the stored deployment energy can allow an under-constrained deployable system to transition to an expanded configuration. A tensioning system can transition an under-constrained deployable system to a deployed configuration.

Abstract: A truss is disclosed in which rigid longitudinal members define a frame and flexible connecting members permit the truss to collapse into a stowed configuration or expand into a deployed configuration.

Abstract: A unidirectional elastomeric composite comprises a plurality of fibers generally aligned in a first direction with an elastomer filling the space between fibers. The plurality of fibers may comprise an intermediate modulus carbon fiber. Preferably, the plurality of fibers have an ultimate elongation at failure or tensile failure strain of 1% or greater, a tensile modulus between 200-400 GPa and tensile strength greater than 4 GPa. The resin or matrix may be a passive elastomer that will maintain its mechanical and chemical properties at a specific operational temperature range. Elastomers are polymers with viscoelasticity, generally having low Young's modulus and high failure strain. Methods of manufacturing the unidirectional elastomeric composite include apply the resin to fibers maintained in tension to maintain the fiber alignment.
