Abstract
This invention relates in general to the preparation of near zero CTE (coefficient of thermal expansion) film-based structural components from aromatic heterocyclic, molecularly oriented, or lyotropic liquid crystalline, polymers, and to the use of such near-zero CTE film based structural components for the preparation of space-based structural members, especially film-based components used in the construction of satellites, space craft, space stations, space-based mirrors, e.g., for the Strategic Defense Initiative, and the like.
