Research

Advanced Computational Modelling

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.

Structural Metamaterials (Auxetics)

Composite metamaterials (auxetics), with a negative Poisson's ratio, carefully engineered for specific properties, can deliver exceptional material performance under several loading conditions.

This project exploits the use of 3D-printed composite metamaterials, produced within the Advanced Composites Research Group’s laboratory and exploited in different forms to provide (i) energy absorption; (ii) improved indentation/fracture resistance; and (iii) crashworthiness.

Material Characterisation

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.

Structural Applications

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 explores the interfacial bonding of thermoplastic laminates over-moulded with injected thermoplastic.

ARTEMIS SIP

ARTEMIS Strength In Places

ARTEMIS SIP (Strength In Places) is a collaborative research project between members of the Belfast Maritime Consortium including the ACRG at Queen's University Belfast. This project is focussing on four key areas within the ACRG: - Modelling and assessing impact damage in efoil-powered composite marine structures - Hybrid titanium–CFRP laminates for bolted joints in high-performance vessels - Application of Artificial Intelligence (AI) in predicting failure of composite structures - A New Test Method for The Interface Characterization of Hybrid Materials
