Summary:Carbon nanotubes (CNTs) grafted on fibres are widely used to reinforce composites and improve the fibre/matrix interface. This study concerned the tribological and adhesion properties of CNTs grafted on carbon fibres by the flame method. Reciprocating friction and adhesion tests were performed to examine the resistance of the CNTs on the fibres in different grafting conditions (various catalysts). Friction results show that under a normal load higher than 1N, CNTs are totally removed after 2000 cycles of friction with catalyst n.2 while they are still present on the surface with catalyst n.1. Adhesion tests show that CNTs are quite resistant to the tack test, and that the CNTs/CFs interfaces seem instantaneously more resistant with the use of catalyst n.2. •Friction and wear of carbon nanotubes (CNTs) grafted on carbon fibres (CFs).•Adhesion of CNTs grafted on CFs by the flame method.•Optimisation of the choice of metallic catalyst used in the flame method.•Mechanisms occurring during tack measurement on surfaces with CNTs grafted on CFs.
