Abstract

A fundamental limitation for using fiber reinforced polymer composites in fabrication of reflective mirror substrates for space telescopes is the fiber print through phenomenon. Because of fiber print through, the typical surface roughness of composite substrates is orders of magnitude higher than what's required for IR and visible optics. This paper presents and demonstrates a new approach to overcome this inherent problem with composites, thus allowing these materials to be considered for mirrors operating in the IR and possibly the visible range of the electromagnetic spectrum.
