Metal-Clad Graphite/Epoxy Tubes

Structural parts feature low weight, low thermal expansion, and high stiffness. Unique, non-labor-intensive manufacturing process developed for fabricating aluminum-clad graphite/epoxy (Gr/E) struts which meet Space Station requirements. Method of manufacturing struts provides procedure for using Gr/E material system in very efficient manner. Technique places all fibers in longitudinal direction for stiffness and strength. Aluminum surfaces provide transverse strength and resistance to atomic oxygen in environment.
