Glass fibres coated with flame synthesised carbon nanotubes to enhance interface properties

Abstract Carbon nanotubes (CNTs) were coated onto glass fibres (GFs) using a one-step flame synthesis method. The GF/epoxy resin matrix interfacial bonding strength was investigated by fibre bundle pull-out tests. Results showed that, compared to the as-received GF/epoxy, Significant interfacial bonding strength enhancement of ∼33% was obtained for CNT-coated GFs/epoxy. Moreover, the wettability of CNT-coated GF by epoxy was increased significantly evidenced by reduced CNT-coated GF/epoxy contact angles reduction. The flame synthesis method possesses the potential of efficient high-performance composites fabrication.
