The materials group works with a wide range of materials from high performance composites, membranes, nanocomposites, lightweight metals and sustainable materials to biomedical materials. This research is supported with excellent facilities that allow the group to meet industrial needs as well as to perform both fundamental and applied research.

The group's principal aim aim is to meet industrial needs with timely solutions and address bottlenecks to niche materials applications.

Current study and development focuses on novel materials using different techniques such as embedded sensory-systems, nanoreinforcements or microcellular foaming in order to reduce weight and enhance performance and durability.

In addition clients are supported with structural analysis and design optimisation techniques for lightweight constructions to reduce material requirements and different joining techniques. This way best performance can be ensured while taking advantage of the properties of the new materials.

Key areas of research are:

Advanced Materials and Nanomaterials

Lightweight materials research is focused on structural materials improvements to meet lightweight design and functional requirements during the product life cycle.

Extensive experience of the preparation and performance of material tests enables the group to offer the best advice on testing methods and suitable characterisation techniques.  A variety of tests for the static characterisation of metals, composites, and plastic materials can be performed. They include, amongst other things, tensile testing, compression testing, bending testing and shear testing.

Structural integrity

Structural integrity is concerned with determining the performance, durability and safety of equipment that is subjected to a range of operating conditions during use.

The consequences of structural integrity failure can be tragic in terms of loss of life and financially crippling due to loss of production and revenue. This work involves a combination of strategies, including sensors embedded systems that monitor, assess and evaluate structural integrity. It therefore aims at addressing design problems, optimisation strategy and developing customised solutions to allow clients (mainly in the transport and energy sectors) to confidently assess the integrity and performance of structures, plants, components and equipment.

Modelling and simulations

Finite element, numerical methods and molecular dynamics are developed and combined to serve applications’ demand including multi-physics problems.

Model materials and structures are tested using numerical codes and finite element analysis (FEA) tools. The research aims to quantify structural dynamic behaviour, study failure and establish the structure-property relationship. The group has leading expertise in lightweight structures, particularly subject to impact, blast, crash, vibration and fatigue loadings. There is also  extensive experience in modelling sensors, micro/nano devices such as miniature energy harvesting devices and accelerometers.

Modelling and Simulations


Membrane technology is a scientific approach for the transport of substances with the help of some porous or permeable membranes.

In general, mechanical separation processes for separating gaseous or liquid streams use membrane technology. Some application can include production of drinking water by reverse osmosis and filtrations in the food industry or recovery of organic vapors in petrochemical productions.

Over years the group has refined membrane technology and processing to develop advanced permeable membranes such as ceramic and polymer membranes. Today these membranes are widely used in industrial processes for separating gaseous or liquid streams.
