Advances In Composites For Terahertz Radio Astronomy

Authors:
S.J. Connell, D.A. Giles
Abstract:
In recent years, Composite Optics, Inc. (COI) has made significant advances in the use of carbon fiber reinforced polymer (CFRP) composite materials for astronomical instrument applications. The inherent low density, high stiffness, and excellent thermal stability of CFRP makes this class of material a natural candidate for many astronomy applications, particularly for space-borne instruments. In recent years, research and development at COI has focused on how to reap these inherent benefits in astronomical applications where other demanding requirements also exist. Basic research has focused on material and process improvement, resulting in an 4 – 5× improvement in the accuracy, homogeneity, isotropy, and thermal stability of the basic material. This has been accompanied by the design, fabrication, and test of large prototype reflectors that cover a broad wavelength spectrum of astronomical interests. Three examples are: a passively adjusted 3-meter aperture prototype reflecting surface for the Large Millimeter Telescope (LMT), the 2-meter aperture prototype mirror for the Far InfraRed and Submillimeter Space Telescope (FIRST), and a 1.6-m prototype for the Next Generation Space Telescope (NGST).
