  2. Typical Skin Design: AV-8 Harrier Embedded Stiffening Fibers • Multiple Metallic Frames • Metallic Longerons • Small Stringer-Stiffened Shear Panels Large Frame Spacing Panels Removable for Inspection Composite Performance:X-34 RLV Primary Structure • X-34 Skin Design • Graphite/Epoxy Skins over Aluminum Honeycomb Core • Large Panel Design (6’-15’ Panel Length) • No Longerons in Design; Unidirectional Stiffening Fibers Embedded in Skin

  3. Composite Performance:X-34 RLV Primary Structure • Higher Strength-to-Weight and Stiffness-to-Weight Than Metallic Structures • Leads to Reduced Vehicle Weight • Allows for Higher Design Factors of Safety • Results in More Robust Structure with Increased Reliability • Fewer Parts • Reduced Cost for Drawing Production, Part Tracking, and Assembly • Fewer Joints • Results in Stiffer Structure • Leads to Increased Reliability Composite Usage Successfully Demonstrated in Structural Test
