Within the scope of FLOWER, the AMM Research group will be especially in charge of undertaking ageing and low velocity impact testing on the developed biocomposites due to its strong degree of expertise in these areas. For most of the FLOWER developments, especially flying boat and materials for point of sale advertising, understanding of ageing behaviour is crucial and needs specific investigations. In this, the Portsmouth team, in collaboration with end users, INRA, Cambridge, Kairos and UBS is responsible for environmental ageing to estimate the evolution of mechanical, fatigue and impact performances of materials throughout their life time.

 

University of Cambridge

https://www.natmat.group.cam.ac.uk/

The Centre for Natural Material Innovation (CNMI) at the University of Cambridge draws experts from a number of disciplines, including the Department’s of Biochemistry, Plant Sciences, Chemistry, Architecture, and Applied Mathematics and Physics, to together solve both applied and fundamental challenges in the replacement of conventional building materials (concrete and  steel) with low-embodied energy plant-based materials. The CNMI have a strong track record in across-the-scales research, which is a major asset for the FLOWER project: from molecular-level biomechanical analysis of plant cell walls, to polymer impregnation  of cells, to design and testing of macro-scale composites. Specific to the FLOWER project, the Centre will bring expertise in the development of optimised flax reinforcements and composites for structural applications of the project (e.g. JEC Asia 2012 Innovation award for world’s first flax composite wind turbine blade). Apart from contributions in project management, communication and dissemination, the Centre will be a key member of the manufacturing process (monitoring of liquid impregnation) and prototype development team, as well as monitoring composite health through advanced imaging techniques such as tomography. As part of FLOWER, Dr Darshil Shah (CNMI) and Dr Alain Bourmaud and Prof Christoph Baley (UBS) will co-supervise PhD candidate, Delphin Pantaloni.

 

Teillage Vandecandelaère – Depestele

https://www.groupedepestele.com/

Europe’s leading private flax producer, Teillage Vandecandelaère operates approximately 8000 ha of farmland in Normandy, and uses all the cultivated crop for various products: long fibres, short fibres, shives and seeds. An integrated processing unit allows it to produce rovings and woven reinforcements using fibres harvested from dedicated crops. These semi-finished products can   also be commingled or pre-impregnated with thermoplastic or thermosetting resins. Teillage Vandecandelaère integrates physiochemical fibre treatments that substantially improve the impregnation capability and the mechanical performances of its products, as well as accurate finite element simulations for the design of composite parts. During the FLOWER project, Teillage Vandecandelaère will take part in several actions: • Provide dedicated flax fibres to achieve required performances • Provide the selected fibres to EcoTechnilin for the development of light non-woven fabrics • Develop non-crimp fabrics and woven grids • Participate in optimising the fibre/matrix interface by using specific fibre treatment methods • Participate in the finite element design of the demonstrator structure for the naval and automotive sectors • Participate in communication actions at international composite trade shows and exhibitions (JEC, CAMX and Composite Europe).

 

EcoTechnilin

EcoTechnilin is a Norman company specialised in the production of composite reinforcements made of natural fibres. They mainly produce nonwoven felts (about 1000t/year) for the automotive industry (interior parts) and dyr and pre-impregnated reinforcements for technical applications such as sport and leisure, design furniture and transport. EcoTechnilin now belongs to the norman agricultural cooperative group Capseine which comprises of 5400 producers, 3800 members and 1 148 employees on 180 sites. For 2017, they generate a turnover close to 1 billion euros. Since 2011, to improve their knowledge, and to offer new innovative products to the automotive industry, EcoTechnilin created a research and development unit. Thanks to close relationships with suppliers, clients and research laboratories, the company has acquired strong know-how in biocomposite processing, as well as transformation of natural fibres into nonwovens. EcoTechnilin has also broadened FLOWER’s range of accessible markets by developing new light products for the building and naval industries. FLOWER would allow EcoTechnilin to pursue this innovation strategy by developing light-weight product that could be used by both the automotive and naval industries. By collaborating with the flax supplier (Teillage Vandecandelaère), parts makers (Howa-Tramico and Kaïros) and research laboratories, EcoTechnilin will produce light-weight nonwovens preserving the full potential of the reinforcing fibres. This new reinforcement will allow weight savings and improved mechanical performance, helping the industries to offer enhanced solutions that promote the uptake of natural fibres in the composites industry.

 

Kaïros

http://www.kairos-jourdain.com/

Kaïros Company supports manufacturers in all industries to integrate green materials and biocomposites in their products. Reducing environmental impact and innovation through high-performance biocomposite materials is at the heart of Kaïros’ eco-design approach. To fulfil sustainability requirements, Kaïros has put a strong emphasis on biocomposites materials. Through FLOWER, Kaïros aims to integrate lightweight flax reinforcements with optimized architectures, including non-woven and biaxial reinforcements completely free of twist and crimp. For Kaïros, these developments are crucial to improve both the stiffness/weight ratio and the environmental impact of its products. Thanks to the strong academic and industrial expertise in the FLOWER consortium, Kaïros expects to 1) design biodegradable materials for point-of-sale advertising offering different end-of-life possibilities (composting, recylcing, energy recovery) and 2) build a hydrofoil sailing yacht demonstrator, enabling a reduction in drag and allowing greater speeds. So far, biocomposite materials have not been considered for these advanced hydrofoils (typically made from carbon materials). Kaïros has already integrated flax in   boats and now aims to fly with it through the FLOWER project. By participating in this project, Kaïros aims to create new knowledge on the use of flax materials and the benefits of the developed flax reinforcements to strongly increase the quality and environmental footprint of its products.
