This paper reports microscopic investigations of the propagation of cracks along polymer-glass and polymer-metal interfaces. The experimental methods include an asymmetric double cantilever beam in an optical microscope, and bire-fringence and atomic force microscopy of the crack faces. The crack fronts propagate inhomogeneously in space and time by way of forward bursts that spread laterally along the front over a certain distance. Experimental indications for correlation between crack propagation and interface roughness and for the occurrence of shear-bands in front of the propagating interface cracks are discussed.
