Abstract
- • Friction and wear of glass fabric reinforced epoxy composites. • MoO 3 /CNTs modified glass fabric reinforced epoxy composites. • Friction and wear of MoO 3 /CNTs modified glass fabric reinforced epoxy composites. A hybrid material composed of MoO 3 nanobelts and oxide multi-walled carbon nanotubes (MoO 3 -CNTs) was prepared via a one-step hydrothermal method. A modified vacuum filtration technique was used to prepare uniform MoO 3 -CNTs films (f -MoO 3 -CNTs). These MoO 3 -CNTs and f -MoO 3 -CNTs were used to enhance the tribological properties of a glass fabric-reinforced epoxy (GF/EP) composite prepared using the vacuum-assisted resin transfer molding (VARTM) method. Wear tests were carried out by using a ball-on-disc ("steel-on-polymer") configuration under dry sliding conditions. The hybrid material acted as both the lubrication and reinforcement to improve the friction and wear performance of the GF/EP composite. The frictional coefficient decreased from 0.61 for the neat GF/EP composite to 0.50 for MoO 3 -CNTs/GF/EP and to 0.32 for f -MoO 3 -CNTs/GF/EP. The wear resistance of the GF/EP composite improved by about four times with the addition of f -MoO 3 -CNTs. The morphologies of the worn surfaces of the composites and their possible wear micro-mechanisms were investigated. [ABSTRACT FROM AUTHOR]
