- Abstract
The aim of this work was to investigate the effect of surface modification of carbon nanotubes (CNTs) on the mechanical properties of polyimide (PI) composites with and without MoS. A three-phase system of CNT/PI/ MoS laminates were fabricated with an extrusion-grade PI to produce CNT-reinforced laminates with MoS volume fractions of 1-5%. The tensile and impact properties of CNT/PI composites and CNT/PI/MoS laminates were also measured and compared. Results showed that the introduction of CNTs as reinforcing additives improved the tensile properties of the composites, but worsened their impact properties. Furthermore, the addition of MoS increased the impact strength of the CNT/PI composites greatly. The optimum contents of CNT and MoS have been found.
