We propose a bidirectional dynamical X-ray phase imaging method based on diagonal continuous fringe scanning using a two-dimensional Talbot interferometer. Tensile testing of carbon fiber reinforced plastic (CFRP) was continuously observed at SPring-8 BL28B2. From the acquired moiré image sequences, an absorption image, differential phase images, and scattering images corresponding to the X and Y directions were obtained with a temporal resolution of 200 ms. The signal extraction principle and the observed internal structural changes in CFRP are presented.
