摘 要：<正>Although in-situ growing carbon nanotubes（CNTs） on carbon fibers could greatly increase the matrix-dominated mechanical properties of carbon/carbon composites（C/Cs）,it always decreased the tensile strength of carbon fibers.In this work,CNTs were introduced into unidirectional carbon fiber（CF） preforms by electrophoretic deposition（EPD） and they were used to reinforce C/Cs.Effects of the content of CNTs introduced by EPD on tensile property of unidirectional C/Cs were investigated.Results demonstrated that EPD could be used as a simple and efficient method to fabricate carbon nanotube reinforced C/Cs（CNT—C/Cs） with excellent tensile strength,which pays a meaningful way to maximize the global performance of CNT—C/Cs.
