Physical and mechanical properties of high-modulus carbon fiber crimped by ion irradiation

摘要

The experimental results of ion-induced crimping of the high-modulus carbon PAN-fibers using nitrogen, neon and argon ions with energies of tens keV are presented. Ion-induced surface nanostructuring of the formed crimps provides more than a hundredfold increase in the specific surface area of the fiber and its shrinkage that retains in thermal processes in the production of composites.
