Structure-Property Relations and Reliability Concepts

Typical procedures currently employed in engineering design are reviewed and applied to the evaluation of composite technology as it exists at this time. Special attention is directed to the topics of stiffness, static strength, specific weight, fatigue, structural reliability and adhesive joining. Verifica tion of the achievement of a safe composite design by a proof-test concept is introduced. Evaluation of composites vis-a-vis metallic technology yields a positive attitude toward the future of composite technology. Significant support is found to justify the long-term potential of advanced filamentary composites.
