Abstract The dispersion of multi-walled carbon nanotubes (MWNTs) in VARTM epoxy resin (EP) was promoted by ultrasonic oscillations to prepare. MWNTs/EP composites through vacuum assisted resin transfer molding (VARTM) process, and subsequently the conductive properties were studied. Results showed that the conductive properties of the composites increased firstly and then decreased with the increase of ultrasonic time, power and frequency, and the composites with different MWNTs concentration had the similar change tendency. The threshold was reached when the ultrasonic time, power and frequency were 90 min, 80 W and 45 kHz, respectively. The addition of 1% MWNTs could reduce the surface resistance of epoxy resin (10¹² Ω·cm) by 4 orders of magnitude. Meanwhile, the dispersion of MWNTs in EP was verified by scanning electron microscopy (SEM).
