N2 - Direct grafting of carbon nanotubes (CNTs) on fibre textiles is a promising strategy to functionalize conventional fibre-reinforced polymer composites with extra merits such as integrated sensing capability. In this study, CNTs are in situ grafted on glass fibre (GF) via chemical vapor deposition at a low synthesis temperature (500 °C). By regulating the mass fractions of CNTs, the quantum tunnelling effect can be triggered among CNT nanoparticles, with which the CNT-grafted GF textiles manifest high sensitivity to structure-guided ultrasonic waves in a frequency regime from 175 to 375 kHz. With ignorable degradation in mechanical attributes due to this direct grafting processing as affirmed by ASTM-complied tests (ASTM C1557 and D3039), the CNT-grafted GF textiles demonstrate the great potential in developing hybrid functional composites.
