Carbon aluminium automotive hybrid structures

In 2016, Constellium and automotive partners launched the Carbon Aluminium Automotive Hybrid Structures (CAAHS) project: a 2-year research programme sponsored by the UK’s innovation agency Innovate UK. The CAAHS project aims to further develop the next generation of aluminium alloy materials and processes for application in automotive body structures.


The expertise from the five collaborating partners including BCAST at Brunel University London, Bentley Motors Ltd, Constellium, Gordon Murray Design (Lead Partner) and Innoval Technology resulted in a new generation of Gordon Murray Design’s iSTREAM® lightweight automotive structure that offer 40% weight savings compared to the original steel-based system.


To achieve these results, the project featured Constellium HSA6™ high strength aluminium alloys and recycled carbon fibre panels as well as a variety of forming and joining techniques from the Advanced Metal Casting Centre and Advanced Metal Processing Centre facilities at BCAST, Brunel University London.


The CAAHS project has been shortlisted in the Manufacturing Technology category for The Engineer’s Collaborate to Innovate Awards 2018 and is a celebration of collaboration highlighting the strength and depth of UK engineering innovation.
