Development of Fracture Mechanics Maps for Composite Materials. Volume 2.

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 resins. 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. Volume 2 includes the following: Response of Mechanically Fatigued Notched Specimens; Response of Thermally Fatigued Un-Notched Specimens; Strain Capabilities and Strain Rate Effects in Epoxy Resins and Laminates; Radiative and Oxidative Effects; FractographicaL Investigations; Fracture Mechanics Aspects; Evaluation of Fracture Models; and Mechanisms of Fracture. Keywords: Fiber reinforced composites; Dynamic test; Thermal cycling; Quality control; Static test; Stress Concentration.
