Validation of hydropower bearings demonstrator “based on self-lubricating graphen/2De based polymer composites”

Important results from the project

Project goal according to application: Manufacturing and validation of semi-industrial self-lubricated graphene-based polymer composites bearing. The goal is met and several types of demonstrator have been developed from two different graphene-based composites and commercial bearing materials. Demonstrators tribological properties were tested in different test environments (dry/water and environmentally friendly lubricants).

Expected long term effects

Introduction of graphene-based materials in new industrial application areas. Development of several types of experimental and commercial composite prototypes to evaluate and compare tribological performance and service life. Establishment of a new way of collaboration between bearing manufacturers and end users. The project created a structured platform for joint discussions on challenges, performance requirements and failure mechanisms between material developers and end users.

Approach and implementation

Project reports the development of graphene-based self-lubricating polymer bearing prototypes for hydropower applications. Laboratory tests at LTU confirmed significantly improved tribological performance compared to commercial materials. Surface functionalisation enhanced graphene–matrix interaction, while sustainable lubricants and water were evaluated. Semi-industrial prototypes were validated, increasing technology maturity and supporting reliable, sustainable energy production.
