This proposal aims to study transverse cracking and kinking of composite materials using time-resolved X-ray multi-projection imaging (XMPI) to acquire 3D measurements of such dynamics not possible with state-of-the-art time-resolved tomography. In both cases, XMPI and ML-based reconstruction algorithms will enable their initiation and propagation to be studied in 4D for the first time, shedding new light on these complex damage processes. To further enhance the temporal and spatial resolution of XMPI, we will use a new setup tailored to ID19’s beam characteristics to reach at least 10 kHz acquisition rate.
