Abstract

Metalized polyimide films have become a standard for soft x-ray filters due to polyimide¿s strength and thermal stability. Utilization of polyimide support has led to increasingly larger and thinner filters, and throughput on missions such as the Chandra X-ray Observatory has been increased significantly. Newer missions such as Constellation-X require higher transmission across a large range of energies. To achieve greater transmission, next generation filters must look to even more advanced materials. The proposed innovation is to reinforce ultra-thin polyimide with extremely high strength materials such as Kevlar (polyaramid) or carbon fibers, to create a robust composite filter. At low x-ray energies (
