Abstract This study reports on the investigation of kink bands within a single high performance fiber. Using microfocus XRD in a scanning acquisition mode, kink bands can be visualized along the length of a fiber in a manner similar to other microscopy techniques. Unlike other techniques, however, µ XRD also provides access to internal structural information. For example, from the diffraction data it is possible to reconstruct the complete microgeometry of single kink bands based upon experimental results. This capability opens the door to a range of future studies. This could include tracking the formation and evolution of kink bands in situ, or studying kink bands within fibers embedded within a composite material.
