Rigidized Inflatable Veritex(TM) Structured For RF Antennas, Phase I

Cornerstone Research Group inc. (CRG) proposes to demonstrate the feasibility of a lightweight, deployable Veritex ^TM supporting annulus structure to support large radio frequency (RF) antennas. Veritex^TM composites are similar to other high-performance composites, with the exception that CRG's shape memory polymer (SMP) resin, Veriflex^TM, 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 will develop and evaluate materials and related fabrication technologies based on Veritex^TM, and develop a deployment scheme with built-in redundancy. 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 rigidized inflatable structures.
