Abstract

The sources of dimensional instability in graphite/epoxy structures are numerous and can be both micro or macro in nature. They can be related to environmental changes, part geometry, laminate orientation, microcracking, and other factors. Past and current experiences in working with graphite/epoxy to fabricate dimensionally stable instrument structures at Composite Optics, Incorporated, has given rise to new understanding and techniques for achieving higher degrees of dimensional stability. This paper describes these sources of dimensional instability, provides alternatives for minimizing or eliminating them, and presents test data illustrating the effectiveness of these techniques used to dimensionally stabilize a graphite/epoxy structure.
