Zusammenfassung:Mechanical property characterization tests were conducted on specimens from a three-dimensional, cartesian orthogonally woven carbon-carbon (C-C) material. Tests consisted of tensile and rail shear, which were conducted at room temperature, and compression tests conducted at room temperature up to 2165 C (3930 F). Stress-strain characteristics and acoustic emission instrumentation were employed to infer the mechanics of the fracture initiation process. In addition, a specially developed axial loading stage integral to SwRI's ETEC scanning electron microscope facility was used to view and videotape the crack initiation and development processes. As a result of these studies, a tentative model is described to explain the mechanics of failure in 3-D C-C composites. (Author)
