Damage Mechanisms/Failure Mechanics of Carbon-Carbon Composite Materials.
Abstract
A 100 millimeter (4in) cubic billet of 3-dimensional cartesian weave carbon-carbon material was received in late December, 1977. A series of tests were performed to measure mechanical properties during uniaxial tension, compression, and shear loading. Extensive test development was required as standard tests for these materials do not exist. Strain gages and extensometers were used to measure strain during loading for determination of elastic coefficients. Acoustic emission measurements were performed on selected tests to determine damage thresholds. Failure surfaces were examined in a scanning electron microscope to study failure modes. (Author)
