STRUCTURAL DESIGN CONCEPTS FOR THE EFFICIENT UTILIZATION OF FIBROUS COMPOSITE MATERIALS,
Abstract
The design of compression structures which can utilize the very high uniaxial strength and stiffness of fibrous composites is studied. Basic structural elements, namely, columns, plates and cylindrical shells are examined. Combinations of isotropic metals or composites for biaxial stiffness with unidirectional composites for strength are studied. Tentative failure criteria are established for use in the structural efficiency studies. The analyses indicate that combinations of advanced unidirectional composites with isotropic materials yield substantial improvements with respect to designs utilizing a single material. The promising configurations are: layered combinations of unidirectional composites and isotropic metals; unidirectional stiffeners on isotropic composite tubes; and 'skeleton' or truss-like cylindrical shells with unidirectional composite members.
