英文摘要：

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.
