Unique space telescope concepts using CFRP composite thin-shelled mirrors and structures

Presented are unique concepts for space telescopes and optics, based on carbon fiber reinforced polymer (CFRP) thin-shelled mirror technology. Thin-shell CFRP mirrors have been proven for IR and longer wavelengths and to a large extent, visible wavelength optics. The unique structural/mechanical and lightweight characteristics of thin shells open the design possibilities for advanced space telescopes with active/adaptive mirrors. Low weight and general ease of manufacturing of CFRP structures can result in reduced part-count and inexpensive lightweight telescopes for space applications. Three advanced mirror concepts will be presented in this paper, 1) Advanced stowage of thin-shell mirrors for segmented telescopes, 2) advanced deformable mirror concepts, and 3) simple and inexpensive fabrication concepts using simplified molding tools for space telescope mirrors. Also presented will be empirical data of CFRP thin-shell mirrors and composite structures produced supporting their use for space telescope applications.
