Anti-roll bar for trucks and trains made of composites

The project is investigating the development and manufacture of lighter composite materials as an alternative to traditional metal anti-roll bars

Research to develop a revolutionary high-performance hybrid composite-metal anti-roll bar for trucks and trains has shown that the technology has the potential to spin out into other sectors such as aerospace and could see the UK take a global lead with these products.

Engineers at Performance Engineered Solutions (PES) Ltd are working to produce high-performance hybrid composite-metal anti-roll bar for trucks and trains, co-funded by the UK’s innovation agency, Innovate UK, with Tinsley Bridge Ltd, one of the world’s leading suppliers of anti-roll bars, and the University of Sheffield Advanced Manufacturing Research Centre (AMRC).

The project is investigating the development and manufacture of lighter composite materials as an alternative to traditional metal anti-roll bars. Lightweight anti-roll bars could cut fuel consumption and emissions from rail and heavy road vehicles whilst also improving their reliability.

The previous Innovate UK funded project achieved a significant 65% reduction in the weight of the stabiliser bar by replacing the current solid steel component with a carbon fibre composite member. The new stabiliser bar design achieved this weight reduction without compromising performance, and offered improved durability, given that the carbon composite materials are less affected by fatigue.

The new project will further develop and refine the design of the anti-roll bars and undertake a wide variety of laboratory testing to simulate the conditions that the anti-roll bars will face during their service life.
