Development of Fracture Mechanics Maps for Composite Materials. Volume 4.

Abstract

The Institute for Structural Mechanics of the German Aerospace Research Establishment (DFVLR) has conducted a research program aimed at the characterization of the fracture behavior of carbon-fiber-reinforced epoxy resin. The research effort encompassed a comprehensive experimental and analytical investigation of the response of test specimens under a broad range of material, loading and environmental parameters. By combining an evaluation of global laminate properties with an investigation of micro- and macroscopic modes of failure, the understanding of the fracture and fatigue behavior of carbonfiber-reinforced composites was enhanced. It is expected that the results of the research program and their representation in the form of tables, figures, graphs and maps will assist the design engineer and lead to improved engineering concepts. This volume includes the following appendices: Fatigue Response of Notched Graphite-Epoxy Lamines; Influence of Simulated Space Environment on Carbon Fiber Reinforced Plastic (CFRP); Notched Strength of Composite Laminates; and Growth of Delaminations under Fatigue Loading. Keywords: Dynamic tests; Thermal cycling; Static tests; Quality control; Stress concentration.
