Mr Trevor Allen is a Postgraduate Research Student in Engineering Materials within Engineering and Physical Sciences at the University of Southampton.

Trevor graduated from the University of Bath in 2011 with a MEng (Hons) in Mechanical Engineering with a sandwich year spent at Ultimate Sports Engineering. As an undergraduate Trevor was heavily involved with the University’s human powered submarine project and the University cycling team.

Upon graduating Trevor moved to Germany to work for Canyon Bicycles as a design engineer before returning to the UK to undertake an Engineering Doctorate.

Research projects

One existing barrier to the use of hydrogen in vehicles is the "fuel tank" where very highly pressurised hydrogen needs to be stored safely. Safe storage and transport of either compressed natural gas or hydrogen are challenging engineering issues in their own right, but even more so if we want to use these as environmentally friendly fuels. We not only need to transport these fuels safely and in large quantities we also need to ensure that containment systems are lightweight and not unwieldy.

Current type-3 cylinders (a metal liner with a composite overlay to give the pressure vessel stiffness and strength) are successful designs in that they meet the required testing standards and are safely useable over their lifetime. However, due to the inherent anisotropy of polymer matrix composites the complex multi-scale material behaviour leads to limitations in fully understanding and quantifying the material structure and processes under load.

This project will the availability of CT scanning and associated computing power at Southampton University ( to explore the materials behaviour and failure mechanisms below the surface in three-dimensions without destroying the cylinder.
