Abstract: Specialized equipment, i.e., a single-fiber tensiometer in conjunction with a confocal laser scanning microscope, was used to follow the morphological and structural changes in a single pulp fiber subjected to cyclic mechanical actions that simulated those occurring during mechanical refining. The observations of localized deformations, crack growth, and material weakening provided insight into the changes occurring in single fibers during refining.
