Scale-dependent structural evolution reveals the nanoscale-to-mesoscale mechanism of diameter-dependent strength degradation in carbon fibers.

The nanoscale structural mechanisms that lead to the failure of carbon fiber mechanical properties have not yet been fully elucidated. Here, we reveal the scale-dependent structural evolution underlying the nanoscale-to-mesoscale origin of strength loss in PAN-based carbon fibers. Utilizing an integrated synchrotron X-...
