Graphene mediated erosion resistant protection for wind turbine blades (Advert Ref: RDFC19/EE/MCE/ELMARAKBI)


Project Description

In collaboration with Applied Graphene Materials in the UK, the Northumbria University is looking for a PhD candidate to develop and design new graphene related materials with high erosion resistance for wind turbine blade. Wind turbine blades are predominantly made using fibre reinforced composite materials. While these materials offer high specific strength and stiffness combined with excellent fatigue performance they also have some inherent weaknesses and drawbacks being sensitive to environmental factors such as heat, moisture and UV. In additional the composite structures are sensitive to foreign body impact during use ie rain, hailstones which has been demonstrated to cause significant erosion on the leading edge of the blades exposing fibres of the underlying structure, leading to resultant reduction in efficiency through increased drag (an approximately 5% reduction in annual energy production). The protection of the leading edges of wind turbine blades is an active area of research with new blade designs and manufacturing techniques being introduced as blade sizes increase. Graphene nano-platelet (GNP) coatings offer a unique solution to this problem addressing several aspects of composite degradation and protection. GNP modified coatings have been demonstrated to significantly reduce water uptake and enhance corrosion resistance. It is proposed in this project to explore the degree to which the use of Graphene nano-platelets might be introduced into a coating for composite wind turbine blades and deliver enhanced environmental protection. Specific attention will be given to understanding the degree of protection and mechanism of action that GNP’s might deliver to impact of rain droplets and hail. As expressed above there is evidence to suggest that GNP’s might substantially reduce environmental degradation but little is understood in relation to the mechanical contribution GNP’s might make to resistance of rain droplet impact. Further the study will explore the degree to which the environmental impact and mechanical impact seen on exposure are related.

The Principal Supervisor for this project is Professor Ahmed Elmarakbi.
The Second Supervisor is Mr William Weaver (Applied Graphene Materials).
