Leading the development of state-of-the-art modelling capability, enabling manufacturers of advanced composite structures to reduce the extent of physical testing through virtual testing and design.
Research projects focussing on the prediction of (i) damage in composite structures, when subjected to impact loading, and the associated residual strength when these structures are placed under compressive loading; (ii) the energy absorbing capacity of composites structures during a crash event to assess a composite structure’s crashworthiness.
A major EPSRC funded research programme to explore the use of different carbon nanotube (CNT) assemblies, integrated within a composite aerostructure, for multifunctional applications.
This project exploits the use of high-specification CNTs, produced within the Advanced Composites Research Group’s laboratory and exploited in different forms to provide (i) improved fracture toughness; (ii) lightning strike protection; (iii) integrated anti-icing/de-icing capability; and (iv) in-situ structural health monitoring.
At the heart of every numerical model is the requirement of appropriate material data. Research is underway to develop reliable material characterisation tests at quasi-static and high strain rates.
The acquisition of intralaminar fracture toughness remains a considerable challenge owing to the emergence of new composite material systems with tougher, stronger or stiffer constituents. Research is underway to explore novel approaches towards the development of fracture toughness tests with wide applicability.
The Advanced Composites Research Group is developing a number of technologies in close collaboration with industrial partners to address their needs.
Both low and high TRL research activities are conducted. High TRL projects include a research project with Bombardier & Wrightbus to explore the development of cost-effective composite repair methodologies. Another project with Denroy Plastics is exploring the interfacial bonding of thermoplastic laminates overmoulded with injected thermoplastic.
