Literature Research on the Mechanical Properties of Fibre Composise Materials Analysis of the State of the Art. Volume I. (Schrifttumsrecherche zum Festigkeitsverhalten von Faserverbundwerkstoffen-Analyse des Standes der Technik-)

摘要

This is a comprehensive review of mechanical considerations in the structural use of fiber composite materials, based on 794 references to the literature, with the emphasis on the aerospace application of resin matrix materials with fibres of carbon, glass, boron and kevlar. The report first discusses data on mechanical properties: static strength of plain, notched and jointed material and the influence of impact damage, environment and creep; fatigue behavior under constant amplitude and flight by flight loading, the influence of environment and the effect of load cycling on deformation; residual strength following load cycling and impact. It then presents physical observations of damage development in different structural situations, and available methods of damage detection and measurement. Then follows discussion of the application of fracture mechanics to damage growth and residual strength; methods of stress analysis for loading and environment and prediction of failure; structural design procedures for static and fatigue strength; and inspection methods for ensuring quality in production and safety in service. A section is included on test techniques and methods for determining mechanical behavior of coupons, components and structures, and a section on the absorption of moisture and its effect on mechanical properties. Finally the report surveys the field of structural applications which exploit composite properties, discusses economic factors and construction methodology, and makes recommendations on the further development of fibres and matrices and on future research.
