Strong, lightweight and long-lasting – carbon fibre composites are the ideal material for the mining industry. Corrosion costs the global economy billions of dollars each year due to costly maintenance programs and reduced-service lifetimes. However, drawing from the expert knowledge in both carbon fibre and composites, and resins at Carbon Nexus, mining companies can develop solutions to their biggest challenges, including corrosion and maintenance, new ways to reuse mining waste, and the improved performance of mining components.
PETRONAS PROJECT SNAPSHOT
A breakthrough self-healing coating, developed by IFM researchers at Carbon Nexus, has been successfully applied in the field. The project, in collaboration with global energy group PETRONAS and led by IFM’s Professor Russell Varley, has resulted in self-healing coatings that automatically eliminate cracks or scratches on their surface, preventing rust and long-term deterioration.
The coating utilises tough polyurethane and dynamic boronic ester linkages, allowing for self-healing triggered by moisture. This inherent characteristic enables repeated healing in the same location. Unlike previous research, this coating offers excellent long-term durability and performance while maintaining self-healing properties.
The innovation extends beyond the energy industry, with potential applications in offshore platforms, pipelines and wind turbines where repairs are costly and challenging. The coatings can preserve the built environment and structures better and for longer, reducing cost and enhancing resource efficiencies.

ALBERTA INNOVATES PROJECT SNAPSHOT:
Canada’s Alberta Innovates’ Carbon Fibre Grand Challenge (GFGC) granted $850,000 to a Carbon Nexus research team to develop low-cost carbon fibre from Alberta oilsand asphaltene (AOA). GFGC aims to accelerate the development of large-scale production pathways for short and continuous carbon fibre from bitumen-derived asphaltenes in Alberta, promoting their use in manufactured products. Using the unique facilities at Carbon Nexus, the team were able to successfully demonstrate an AOA-based carbon fibre with the performance exceeding Department of Energy (DOE) target.
