Out-of-plane microbuckle growth is observed in a unidirectional carbon fiber-epoxy matrix composite under compressive loading. Experimental measurements of the overall kink-band width confirm that a growing microbuckle propagates in a crack-like manner rather than in a dislocation-like manner. The microbuckle is modeled as a bridge Mode I crack with compressive bridging tractions. A large scale bridging model with a crack tip toughness and a constant bridging stress is successful in correlating the length and width of a growing microbuckle with the remote stress.
