Development of Elastic Memory Composite Stiffeners for a Flexible Precision Reflector

Abstract

Harris Corpor ation is currently developing a next -generation, large -deployable, solid surface radio frequency reflector, called the Flexible Precision Reflector (FPR). The FPR will significantly advance satellite communication systems by enabling very -large -aperture an tennas to be stowed within existing launch vehicle shrouds at a relatively low cost and part count. Additionally, by replacing traditional mesh surfaces with a furlable composite laminate, the FPR antenna will be capable of operating at radio frequencies a bove 40GHz. To realize the full potential of the FPR design, Harris Corporation is considering the use of Composite Technology Development’s TEMBO ® Elastic Memory Composite materials for critical components within the FPR system. This paper present s the de sign, development, fabrication, and testing of a FPR breadboard model that demonstrates the benefits of incorporating TEMBO ® materials in the design.
