Underpinned by research at the University of Nottingham, the development of automated discontinuous carbon fibre preforming (DCFP) technology has helped drive more than half a billion pounds in sales of Aston Martin's DBS sports car across 42 countries, boosting the company's brand worldwide. Recognising the potential of this process, Bentley Motors invested £1.3M directly to develop this technology for its next generation of models. The Royal Academy of Engineering acknowledged the body of research as an "outstanding" contribution to the reputation of British engineering through the award of a silver medal to Professor Warrior.
Workers at the University of Leeds researched, then developed and patented the `hot compaction' process for the manufacture of single polymer composites [1]. In this process highly oriented polymer fibres are heated so that a proportion of the surface of every oriented element melts. Upon cooling, this skin recrystallises to form the matrix of a self-reinforced fibre composite. Important resultant properties include high stiffness and strength, lightweight and outstanding impact strength, leading to a material with crucial commercial advantage. The reach of this impact is demonstrated by commercialisation of the polymer composite over a wide range of applications including anti-ballistic body armour, sports goods (Nike, Bauer), lightweight luggage (Samsonite), audio speakers (Wharfedale) and radar covers for helicopters (Westland). Examples include Samsonite using the material Curv® to manufacture two new high profile product ranges (Cosmolite and Cubelite) and Bauer using it in their elite-level ice hockey skate range (SUPREME and VAPOR).
Impact: Influencing industry, governmental policy, insurance industry policy and public awareness/engagement.
Significance: By establishing the actual risks posed by specific carbon nanotubes (CNT), UK Health and Safety Executive (HSE) guidance and workplace guidance and industry was influenced internationally.
Beneficiaries: CNT industry and users, governments and policy-makers, the HSE and its international equivalents, the public.
Attribution: Donaldson and colleagues (UoE) published the first demonstrations of potential CNT toxicity.
Reach: Global media coverage, encompassing UK, Europe, USA and India. Results considered by national and international policy-making bodies, for example, House of Lords Science and Technology committee, US National Institute for Occupational Safety and Health.
This research has led to the creation of new business sectors in laser development for medical and healthcare applications, which has enabled the creation of a world-wide market worth US$96 million in 2011, and a local spin-out, Fianium Ltd, which now has more than 50 employees and an annual turnover of around £10 million. Exploiting a radically new optical component invented at the University of Southampton, the microstructured optical fibre (MOF), this research has led to economic benefit through the creation of hundreds of jobs worldwide, and enabled the development of new diagnostic and medical technologies.
Researchers at the University of Southampton were the first in the world to introduce ytterbium-doped silica fibre as an optical gain medium. The work led to the creation of a new business sector around efficient industrial fibre lasers, which enable new manufacturing processes in the automotive, aviation, defence and medical device industries, with a reduction in carbon footprint relative to earlier technologies. The economic impact of this work includes the UK foothold in the $2 billion global industrial laser market through the success of two spin out companies — Fianium and SPI Lasers — with a combined turnover of £50 million, employing close to 300 people
Ulster research groups in the fields of composites and metal forming have had a long-term and fruitful engagement with major industries such as Caterpillar (FG Wilson), Rolls Royce and Bombardier. Since 2008 this has resulted in new patented technologies, significant cost/performance improvement in manufacturing, the delivery of on-site industrial training, the formation of spin-out companies and the establishment of the £6m N. Ireland Advanced Composites and Engineering Centre with currently 10 member companies. In particular, Ulster research has been at the heart of patented Bombardier processes which underpinned their strategic entry into the commercial narrow body aircraft market which is worth $43billion per annum globally. The C Series wing programme, which utilises composites, employs 800 people directly in Belfast at full production, with a further 2,000 employed in the supply chain. As of today, Bombardier has global orders and commitments for 388 C Series aircraft, which include firm orders for 177 of the new airliner.
Ultra-precise Bragg grating writing-technology, invented in the Optoelectronics Research Centre (ORC), has led to impacts in the areas of security, safety, detection of bio-hazards and the underpinning laser technology currently being pursued for clean energy generation for future energy security. This case study highlights two aspects of the technology namely: planar-based for optical microchip sensors in areas such as portable detection of biohazards, which has resulted in the spin-out Stratophase, and fibre-based, inside the US National Ignition Facility (NIF), the world's largest laser system, based in California, built for fusion-energy research, which has ORC fabricated fibre Bragg gratings within its laser amplifier chains. These ultra-high precision laser-written engineered gratings have enabled important advances in biosecurity, management of environmental hazards and clean energy research.
Research carried out by Prof. Ton Peijs and colleagues has led to significant breakthroughs in engineering plastics: PURE® and its licensed Tegris® technology, which are lightweight self- reinforced alternatives to traditional polypropylene (PP) composites such as glass-fibre or natural- fibre-reinforced PP. Environmentally friendly and 100% recyclable, these strong and ultra-light self- reinforced plastics have been successfully used across a number of applications, from suitcases and sports gear to protective armour and automotive panels, with impressive results. When used for car, truck and van components, they have been shown to help lower exhaust emission levels and increase fuel economy.
The A350-XWB is the first Airbus airliner to have composite wings, thereby reducing structural weight compared with the current generation of metallic wings. With over 700 orders for the aircraft, the company has placed great emphasis on the need to maximise performance benefits whilst mitigating risk associated with manufacture of the all-new wing. The Bath Composites Research Unit has supplied underpinning research to:
(1) Develop an algorithm that has been used to design the composite wing skins for optimised performance;
(2) Analyse the laminate consolidation process for the wing spars.
The impact of (1) is a direct saving of 1.0 tonne of fuel per typical flight compared with current metallic skins. This represents a total fuel saving of around 40,000 tonnes, over the design life of each aircraft. The impact of (2) is the achievement of satisfactory part quality for current production rates of spars valued at £1M each when equipped.
This case study is about the development of flame retardant (FR) polypropylene yarns used in upholstery fabrics for domestic and office furniture, automotive and floor coverings that will have predictable and reproducible fire retardant properties when subjected to standard testing procedures. Through the UK DTI funded project FLAMTECH (2002-2005) shared by Camira Fabrics Ltd., and the university, a range of novel polypropylene yarns having higher levels of consistent fire performance than the previously existing products in the market place were developed. A testing protocol which could establish individual fibre/yarn/fabric structural-fire property relationships and correlate these with (and hence predict) final fabric performance was also established. The project overlapped a concurrent EPSRC funded research in which nanocomposite fibres (including polypropylene) with improved flame retardancy and reduced melt dripping were developed. Camira were also members of the consortium managing this project. The major commercial outcome from these projects since 2005 is a flame retardant polypropylene product being marketed by Camira fabrics within their Perfentex brand and others are also being considered. This work also inspired the Production Director of Camira Fabrics to register at Bolton as a PhD-by-publication candidate and hence gain more knowledge about the subject area, as evidenced by the publication of her research papers (see Paper 1, Section 3).
