Qualification of Elastic Memory Composite Hinges for Spaceflight Applications
Abstract
Future small spacecraft will have a need for lightweight, highly reliable, and cost-effective mechanisms for the deployment of radiators, solar arrays, and other devices. To meet this need, Composite Technology Development, Inc. has developed TEMBO Elastic Memory Composite (EMC) materials, which accommodate very high folding strains without damage, while providing very high deployed stiffness- and strength-to-weight ratios. Over the past few years, CTD has developed and performed extensive ground testing on a TEMBO EMC deployment hinge for radiators, solar arrays and other deployable spacecraft components. The present paper will discuss the details of two flight experiments to validate the TEMBO EMC hinge design on-orbit. In particular, the paper will discuss: 1) detailed design of the flight hardware for both experiments; 2) ground-verification and acceptance testing of the flight hardware; and 3) status of the flight missions.
