Structural Degradation in Fiber Composites by Kinking.

Abstract

Some observations of kinking in carbon composites, which identify the modes and morphology of kinking in fibrous materials, are presented. The thermodynamics and mechanics of kinking are analyzed. The analyses indicate the important role of matrix deformation (plastic and elastic) in determining the kink morphology, and identify the matrix yield strength and the distribution of fiber fracture strengths as the primary properties governing kink formation.
