ESR 4: Development of 3D printing multiphase self-lubricating filaments for low friction composites

Objectives: To investigate the effects of filler type and content on the tribo-mechanical properties of polymeric filament for the 3D-printing of a low-friction bearing To understand the effect of grapheme-based nanoparticles on the low-friction, self-lubricating behaviour of the composite filaments. To characterize the mechanical and tribological properties of the bearing prototypes.

This programme was a great option for me to further utilize and develop my knowledge and understanding of tribology achieved while doing my master’s in Tribology of Surfaces and Interfaces. The structure of the programme involving two universities and several partner industries was intriguing as it will allow for a better understanding of lab-to-field transfer of skills and help to enhance the scientific knowledge on the process. The projects involved will contribute towards the reduction of carbon footprint and energy consumption.

Previous studies:
Bachelor's degree: Mechanical Engineering, National Institute of Technology (NIT), Durgapur, India
Master's degree: Joint European Master in Tribology of Surfaces and Interfaces (TRIBOS), University of Leeds, UK; University of Ljubljana, Slovenia; Luleå University of Technology, Sweden

PhD double degree at: Luleå University of Technology & University of Leeds

Expected Results: Carbon-nanoparticles will be used as additive to improve the self-lubricity for the 3D printing of the bearing prototype and to understand the influential parameters affecting the prototype printing of different bearing types. With this, it will be possible to reduce the friction of the 3D-printed bearing with economic and environmental benefits through:

  • Development of the new multiphase polymer composites for the 3D-printing of the bearing prototype

  • Understanding the influence of various filament designs on the friction and wear of polymers

  • Understanding the friction mechanisms of newly developed carbon-based, multiphase, nano-composites on an engineering scale
