Development of Fracture Mechanics Maps for Composite Materials. Volume 1.

Abstract

The Institute for Structural Mechanics of the German Aerospace Research Establish (DFVLR) has conducted a research program aimed at the characterization of the fracture behavior of carbon-fiber-reinforced epoxy resins. The research effort encompassd to 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 miro-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. Keywords: Fiber reinforced composites, Dynmaic test, Thermal cycling, Quality control, Static test, Stress concentrations, Notched specimens, Nondestructive testing.
