Micromechanisms in carbon fiber reinforced plastics (CFRPs) were studied byin situmode II fracture toughness tests using a high-resolution optical microscope. The fracture toughness tests on four-point bend end notched flexure specimens were interrupted between the proportional limit and the plateau region, followed by postmortem examination using a high-resolution X-ray computed tomography system to identify three-dimensional microdamage. The observations sequentially captured the formation of damage zone, which composed of plastic zone, fiber/matrix debonding, and microcracks. The microscopic failure process was correlated with the macroscopic behavior of CFRP laminates during mode II fracture toughness tests.
