Polyarylacetylene Resin Composites

Abstract

Polyarylacetylene (PAA), a highly cross-linked aromatic polymer that has a char yield of 90% when pyrolyzed in an inert environment, has been investigated in a major research and development program designed to realize the potential benefits of this material in space system components. The recent achievements of the Materials Sciences Laboratory in developing the processing techniques needed to fabricate carbon-fiber-reinforced PAA composites are outlined. Large, thick composites were fabricated and were demonstrated in various practical applications. Applications include dimensionally stable space system composite structures, ablative insulators for solid-rocket-motor nozzles and exit cones, and precursors for relatively low-cost carbon-carbon composites.
