Experiment: AO175 Experiment Title: Evaluation of Long-Duration Exposure to the Natural Space Environment on Graphite-Polyimide and Graphite-Epoxy Mechanical Properties Original Principal Investigator(s): P.O.well, Howard - Invest. Role: Original, Welch, Douglas - Invest. Role: Original, Vyhnal, Dr. Richard - Invest. Role: Present, Experiment Description:Graphite-polyimide and graphite-epoxy are two composite materials being used in current spacecraft construction, and both materials are being considered for more extensive use in future lightweight space-oriented structural compo- nents. The accumulation of operational data on the effects of long-duration exposure of these two materials to the multiple environmental elements of space is needed to properly evaluate them for both current and future applications. In particular, data are needed on the mechanical properties of these materials.
