Electrophoretic deposition of carbon nanotubes onto carbon-fiber fabric for production of carbon/epoxy composites with improved mechanical properties

Development of sizing-free multi-functional carbon fibre nanocomposites

“…It has been previously stated that an increase in the interlayer reduces fibre bridging [55], but unlike UD composites this was not observed for any of the materials [53]. An et al [13] suggested that different Vf fractions may not significantly affect the fracture toughness, but this theory has only been applied to composites with only slight variations in Vf.…”

“…They also reported that additional thickness from CNT mat layer decreases in-plane shear strength [45]. Using a double notched compressive IPS test (as per the ASTM D3846 guide [47]), An et al [13] noted a ~70 % increase in τIPS over the baseline material for their ozone-PEI treated MWCNTs that were attached to the CFs via electrophoretic deposition. After spraying a pre-preg with a SWCNT solution, Kim et al [48] reported a 7 % increase in the τIPS.…”

“…An et al [13] reported a 80 % increase in the fracture energy between the ozone-and PEI-treated MWCNTs that were deposited electrophoretically on CFs and CFRP. They observed that the scatter in fracture initiation data obscured clear correlations with treatment times.…”

Influence of carbon nanotubes coatings onto carbon fiber by oxidative treatments combined with electrophoretic deposition on interfacial properties of carbon fiber composite

“…Recently, many grafting methods have been proposed such as chemical vapor deposition (CVD) [11][12][13], chemical grafting [14][15][16] and electrophoretic deposition (EPD) [17][18][19][20]. All methods reported successful attachment of CNTs on the fiber surface.…”

Improvement of interfacial properties of carbon fiber‐reinforced poly(phthalazinone ether ketone) composites by introducing carbon nanotube to the interphase

“…It has been studied that CNT/carbon fiber with a large surface area could lead to better contact with the matrix, thus forming more mechanical interlocking sites [18]. Preparation of the CNT/carbon fiber hybrid fiber has been explored with several methods such as chemical vapor deposition (CVD) [19][20][21], chemical grafting [22,23], and electrophoretic deposition (EPD) [24][25][26][27][28].Since the sizing process is a standard and commercially available method of fiber surface treatment, fabrication of CNT/carbon fiber by the way of sizing is facile and preferred in industry. Fabricating CNT/carbon fiber hybrid fiber had been achieved by sizing carbon fiber in our previous article [29], but the effect of CNT at the interphase on interfacial properties for CFRTP has not been studied.…”
