Research undertaken in the University of Cambridge Department of Physics has provided benchmark data on, and fundamental physical insights into, the high strain-rate response of materials, including powdered reactive metal compositions. The data have been used widely by QinetiQ plc. to support numerical modelling and product development in important industrial and defence applications. One outcome has been the development of a reactive metal perforator for the oil industry which significantly outperforms conventional devices. These devices `perforate' the region around a bore-hole, thereby substantially enhancing recovery, particularly in more difficult oil fields, and extending their economic viability. Over a million perforators have been deployed since their introduction in 2007.
Dr Richard Brooks and his team at the University of Nottingham have been investigating the high strain rate behaviour of composite materials since 2003. This has led to the development of two products that are being installed in streets in the UK and Ireland by East Midlands SME Frangible Safety Posts Ltd. The direct benefits to the company have been: the installation of 900 products in the UK and Ireland; saving of £17k capital cost and 2 months in terms of time to market per product developed and; raising of £1.8M investment to bring the products to market At least one life has already been saved in the Shetland Islands as a direct consequence of the product behaving in the way it was designed to.
The impact presented in this case study is the commercialisation of 15 products with perfume microcapsules by Procter and Gamble (P&G), made possible using capsule mechanical strength data provided by Prof Zhibing Zhang's research group at Birmingham. Use of microcapsules gives improved freshness performance, and thus commercial advantage, compared with traditional formulations; they have been incorporated in P&G's four major billion-dollar brands — Downy, Febreze, Lenor and Tide. This has significantly improved their competitiveness enabling P&G to retain their leading position in the USA and Western Europe. A novel micromanipulation technique developed at the University of Birmingham has been used extensively to obtain mechanical properties data for the micro-particles, including microcapsules prepared in Birmingham and provided by companies, which is related to their formulation and processing conditions and end- use performance. In addition, the knowledge generated has helped 15 other companies to commercialise new functional products containing micro-particles.
University of Bradford research has enabled a material manufacturing company, Armacell, to reuse up to 95% of its production waste to produce new, high-value acoustic products with up to 50% better acoustic performance than any competition products of similar size. We protected the developed IP through several international patents and set up a spin-off company, Acoutechs Ltd, to explore this technology commercially. These materials are now used to reduce noise levels below the recommended limits and to improve the general acoustic quality of spaces at home and work for the benefit of public health. The products generate an annual turnover of more than €4 million for Armacell and prevent more than 500 tonnes of plastic waste from going into landfill annually.
For aerospace vehicles, the development of new materials and structural configurations are key tools in the relentless drive to reduce weight and increase performance (in terms of, for example, speed and flight characteristics). The economic drivers are clear — it is widely recognised that it is worth approximately $10k to save one pound of weight in a spacecraft per launch and $500 per pound for an aircraft over its lifetime. The environmental drivers (ACARE 2050) are also clear — reduced aircraft weight leads to lower fuel burn and, in turn, to lower CO2 and NOx emissions. With such high cost-to-weight ratios, there is intense industrial interest in the development of new structural configurations/concepts and enhanced structural models that allow better use of existing or new materials. Analytical structural mechanics models of novel anisotropic structures, developed at the University's Advanced Composites Centre for Innovation and Science (ACCIS), are now used in the industrial design of aircraft and spacecraft. Based on this research, a new, unique anisotropic composite blade, designed to meet an Urgent Operational Requirement for the MoD, is now flying on AgustaWestland EH101 helicopters that are deployed in Theatre. In addition, the new modelling tools and techniques have been adopted by Airbus, AgustaWestland, Cassidian and NASA and incorporated into LUSAS's finite element analysis software. These tools have, for example, been used to inform Airbus's decision to use a largely aluminium wing design rather than a hybrid CFRP/aluminium wing for the A380.
Research into a number of different aspects of rubber has fed into a series of extremely successful collaborations between Queen Mary and a large number of industrial partners. This has led to significant economic impacts, ranging from enhancing the performance of teams in the multi-billion dollar sport of Formula 1 Racing, to helping develop new UK designed and manufactured radial tyres for large civil aircraft. Rubber research has been undertaken continuously at QMUL for over five decades. Prof. James Busfield has led the activity since 1994, working with more than 30 major industrial collaborators, including Bridgestone, Dunlop, Red Bull Racing F1 and TARRC, who have applied our research and employed our researchers to achieve commercial and competitive advantage.
The investigators of this impact case study have utilised their expertise in materials engineering, theoretical/numerical modelling and product development to achieve significant economic, social and environmental impacts in a range of fields through developing a systematic methodology for innovative product design and optimisation. Through several industrial projects and collaborations, significant impacts have been witnessed including new products creating several million pounds in revenue annually for businesses in different sectors and green manufacturing technologies in repair and reclamation of components. All the described impacts were results of investigation in the Mechanical Engineering and Materials Research Centre (MEMARC) over the assessment period.
The research produced accurate simulation models of piezoelectric actuators for investigating sensitivities to parameter variations that led to maximum power for minimum electric field. This was the basis of design rules for determining new products at the industrial partner NXT, now named Hi-Wave Technology, headquartered in Cambourne, UK. Old design rules had led to two failed products whereas these new design rules have guided successful products with a major Japanese television manufacturer, a Japanese printer company and a Russian mobile phone company. Without this research Hi-Wave would have stopped activities in this technology. To date, licences for more than 24 million units per annum have been sold and more than 280,000 units manufactured.
Impact on industry, academia and government institutions from engineering materials research in the Mechanical Engineering department has been delivered through it directly leading to UK, USA and International Standards and Codes relating to three themes:
The results of the research of staff in this unit have led directly to UK, US and International Standards and Codes: ASTM Standards E1457-07 (2012) and E2760-10 (2012); R5 EDF Energy Code of Practice (2012); BS 7910 (2013); ISO 25217 (2009); ISO CD 15114 (2011) and ISO 13477 (2008). These documents all cite peer-reviewed publications by staff from this unit. These Standards and Codes are now the basis of fracture-mechanics methodologies used by leading engineering companies like Airbus, EDF, E.ON, GKN, Rolls-Royce and Vestas, whose commercial success depends upon technological leadership. In this way our research has led to savings by UK industry of many millions of pounds, as detailed in Section 4.
Research conducted at the Geoenvironmental Research Centre (GRC), supported by the European Commission via its EURATOM programme, has been instrumental in addressing the long standing global problem of high level nuclear waste disposal. The pioneering development of a sophisticated coupled thermal/hydraulic/chemical/mechanical model of clay behaviour has provided new understanding of the performance of engineered barriers proposed for use in nuclear waste repositories. This has, in an unprecedented development, directly enabled the design of numerous nuclear waste repositories to proceed. The repositories in Sweden and Finland are currently at "Licence application" and "Construction" phases, respectively. Therefore the impacts claimed during the REF period are: significant impact on engineering design, leading to improved environmental conditions; considerable economic investment and marked impact on public policy and services.
