In a drive to improve performance and save money through fuel efficiency, engineers are moving away from using traditional metals and now rely on lightweight carbon fibre composites. These are currently used in the fuselage and wings of the Boeing's 787 Dreamliner and the Airbus's A350, in the wings of the Bombardier C-Series planes, in the structure of racing cars and in some high-end road vehicles.
However, there are strict regulatory procedures in place and rigorous safety testing is required before these designs can enter service, which can be costly and can limit designers in trying new things.
Professor Falzon says that this ground-breaking research at Queen’s will now allow companies in the aerospace, automotive and rail industries to try new designs virtually, which will rule out any safety concerns without having to incur huge costs in physically testing these designs. Through the project, researchers will further explore the development of new generations of composite materials, using nanotechnology, which could improve safety even further.
He explained: “At Queen’s, we are training the next generation of researchers in this area and have developed a cutting-edge computer system which uses virtual testing to predict how carbon fibre composites will react when impacted, when crushed, or when put under extreme loading – allowing for improved crashworthiness design and reducing impact to passengers.
“Using mathematics and computer software, our Advanced Composites Research Group at Queen’s has developed a system which is as close to reality as possible and can pick up problems that may not always be visible, such as internal wing damage on a plane which may occur during operation. By understanding the failure mechanisms of composite materials such as carbon fibre, we are able to better exploit their unique properties and create very lightweight transportation structures. This will minimise environmental impact whilst ensuring utmost safety to passengers.”
The €4m European Union H2020 Marie Sklodowska-Curie Innovative Training Network award is being coordinated by Queen’s and includes an inter-disciplinary research consortium of experts from Universities, Research Institutions and Industry, across six European countries; the UK, Sweden, Italy, Greece, Ireland and Germany.
Through the programme, fifteen early stage researchers will be trained up to become experts in this area, four of which will be registered at Queen’s University.
