Abstract:

Impact-induced damage mechanisms for GE 2-2-3 Carbon-Carbon have been identified for both axial and transverse fiber bundles, and changes in the nature and severity of damage have been observed as a function of location with respect to the impact crater geometry. Although axial fiber bundles exhibited column buckling failure when immediately beneath an impact crater, they were relatively intact except for tensile cracks in some individual fibers at positions alongside or away from the major craters. Transverse fiber bundles, however, showed column buckling failure in locations alongside or between craters, while only flexural-type failures were noted in locations directly below a crater. Author
