Abstract In this research, the micro-milling process using nano-solid dry lubrication is studied for machining multidirectional carbon fiber reinforced plastic (MD-CFRP). For the nano-solid dry lubrication, two kinds of graphene nanoplatelets and multiwall carbon nanotubes are used as nanoparticles. The workpiece is an MD-CFRP composite in which 10 plies of prepreg are laminated and it consists of four carbon fiber orientations — 0°, 45°, 90°, 135°. After a series of micro-milling experiments, the workpiece surface quality and tool wear are investigated. Overall, it is found that the nano-solid dry lubrication can improve the surface quality and reduce the tool wear. In particular, larger graphene nanoplatelets (xGnP H-5) are more advantageous than smaller graphene nanoplatelets (xGnP C-750). In addition, multiwall carbon nanotubes having a tube-shape structure are less effective than graphene nanoplatelets having a two-dimensional thin sheet shape for enhancing the micro-milling performances, which may be due to better lubrication effect with the graphene nanoplatelets’ sliding phenomenon at the cutting region.

The workpiece is an MD-CFRP composite in which 10 plies of prepreg are laminated and it consists of four carbon fiber orientations - 0°, 45°, 90°, 135°. The micro-milling experiments are conducted, and the workpiece surface quality and tool wear are investigated. As a result, it is confirmed that the nano-solid dry lubrication can improve the surface quality and reduce the tool wear. In particular, larger graphene nanoplatelets (xGnP H-5) are more advantageous than smaller graphene nanoplatelets (xGnP C-750).

Carbon Fibre Reinforced Plastic

The usage of joints between composites and metals has gained significant importance in the recent years and it is the need of the industry that new and improved methods of joining the composites and metals be introduced. In this study, the joint between the carbon fibre reinforced plastic composite and the aluminium metal has been improved with the help of the multi walled carbon nanotubes to reinforce the epoxy adhesive. Knowledge of the interlaminar behaviour regarding the composites is very important as this is the most common type of failure faced by them. Furthermore, the best method for the uniform and fine dispersion of carbon nanotubes in the epoxy is also discussed. In this research, two different types of composite metal joint samples were tested using the mode 1 fracture toughness test to study the interlaminar behaviour of the reinforced epoxy and the double cantilever beam specimen was used to carry out the tests according to the ASTM standards.

By exploiting the dispersibility and rigidity of boehmite nanofibers (BNFs) with a high aspect ratio of 4 nm in diameter and several micrometers in length, multiwall-carbon nanotubes (MWCNTs) were successfully dispersed in aqueous solutions. In these sols, the MWCNTs were dispersed at a ratio of about 5–8% relative to BNFs. Self-standing BNF–nanotube films were also obtained by filtering these dispersions and showing their functionality. These films can be expected to be applied to sensing materials.
