Materials development for precision segmented reflector applications

Abstract

The requirements developed to guide the selection of current and future materials for precision segmented reflectors are presented along with a list of desirable properties. Some potential candidate materials including modified fiber reinforced organic matrix composites as well as carbon/carbon composites, graphite/glass composites, and metal matrix composites are identified. It is noted that in the near term, it is likely that modified fiber reinforced organic matrix composites have good applicability. In the longer term, materials such as carbon/carbon composites, graphite/glass composites and metal matrix composites may provide the best mix of properties.
