Abstract
The crystal structure and morphology of the KUP-VM (1D) carbon-carbon fiber composite are investigated upon irradiation with 15- and 30-keV Ne+ ions with high fluences (1018–1019 ion/cm2) with the purpose of studying fiber crimping. The results are compared with data obtained previously for N +2 and Ar+ ion irradiation. It is assumed that the formation of regular prismatic topographic elements (crimps) at temperatures near and above the dynamic annealing temperature T a reflects the highly ordered structure of the fiber’s surface shell. The results obtained are discussed within the Bradley-Harper theory.
