Abstract
Phase I results demonstrated the feasibility of using shape memory polymer composites to deploy, tension and support gossamer antennas. Cornerstone Research Group, Inc. (CRG) has completed the critical initial development steps for a deployable support structure meeting NASA's requirements for a structure to deploy, tension, and support gossamer antennas. CRG proposes to further develop this lightweight, self-deploying VeritexTM strut for use as a supporting structure for gossamer antennas. VeritexTM composites are similar to other high-performance composites, except that CRG's shape memory polymer (SMP) resin, VeriflexTM, is used as the matrix resin. This allows for easy manipulation of the composite above the activation temperature, making it a unique material for use in dynamic structures and other applications requiring both load strength and "shape-shifting" modulus flexibility. In this Phase I program, CRG has developed and evaluated materials and related fabrication technologies based on VeritexTM, and produced a sub-scale working proto-type. This technical approach fulfills NASA's requirement for a very large, lightweight, on-orbit deployable RF antenna aperture structure by offering a practical, deployable, structural support that will address the short comings of current rigidified inflatables and mechanically deployed structures.
