8 High-Reliability Structural Materials Space/Satellite/Launch Vehicles TenCate materials are widely used on satellites and space structure as a result of their performance characteristics and successful flight history. TenCate materials have been used on almost every satellite program in the Western world. Satellites and space exploration require materials that can withstand the rigors of space with the ability to resist microcracking and outgassing while enduring radiation exposure and extreme temperature cycling. Launch vehicles require materials which provide high strength and light weight, but which can be processed under vacuum only pressure while achieving low voids. Satellite composite structure must endure extremely harsh environments and thermal cycling. TenCate s technology in lowoutgassing, dimensionally-stable, low moisture prepregs allow the highest performance with unmatched reliability. On satellites, ultra high modulus fibers are utilized for bus structure, solar arrays, reflectors and trusses to create lightweight stable structure. On launch and re-entry vehicles, TenCate materials are used in heatshields, barrel assemblies, fairings and rovers.
