Effect of CNT Surface Coating on the Tensile Strength of Carbon Fibers

Key Points

• This research aims to assess how carbon nanotube coatings affect the tensile strength of carbon fibers.
• Conducted single-fiber tensile tests on CNT/CF coated carbon fibers.
• Evaluated mechanical properties under varying gauge lengths.
• Compared effects of size on tensile strength for conventional carbon fibers.
• Demonstrated that CNT coatings positively influence the tensile strength of carbon fibers.
• Showed a notable size effect where tensile strength decreases with longer gauge lengths in conventional fibers.
