 In early 2014 the American Institute of Aeronautics and Astronautics Spacecraft Structures Technical Committee recognized that the level of active research and development in High Strain Composites warranted an independent focus group to distinguish high strain composites as a technical area with uniquely identifiable challenges, technologies, mechanics, test methods, and applications.The High Strains Composite Technical Subcommittee was formed to provide a forum and framework to support HSC technical challenges and successes, and will promote continued advances in the field.The use of high strain deployable structures dates back to the pioneering days of space exploration and has played a crucial role in enabling a robust spacefaring industry.
