Robotic arms are typically supplied by KUKA AG (Augsburg, Germany), with up to eight axes of movement. "Medium" foor-mounted, robotic arms have a payload capacity of 250 kg, while the "large" option allows a 500 kg payload, and can support a correspondingly larger head. Optional are rotating "positioners," or headstock and tailstock parts, supplied by Güdel SAS (Mulhouse, France). Robotic motion is controlled by Siemens 840D CONTROLLER software from Siemens AG (Munich, Germany). Heads, built and assembled by Coriolis, can be confgured to lay thermoset towpreg, thermoplastic tape or dry tape, with appro- priate heating strategies for the selected material, in widths from 6.4 mm up to 12.7 mm. Customers can specify single or multiple (4, 8, 16 or even 32 simultaneous) tows in the larger heads, explains Hamlyn. Minimum fber laydown length is 90 mm, and speeds up to 1m per second are possible, for laydown rates up to 40 kg of material per hour. A key feature of the company's head design is that tows or tapes move from the creel and Multiwinch tension Thermoplastic composites: European consortia, galore! SIDE STORY There are many more European consortia, comprising private industry, university and government entities, which share the goals of exploring composites materials and methods for manufacturing them, including those with thermoplastic matrices: The Thermoplastic Afordable Primary Aircraft Structure (TAPAS) consortium was launched in The Netherlands in 2009 with the goal of developing new thermoplastic composite materials and processes for use in Airbus (Toulouse, France) aerostructures. The consortium is starting its second phase of material and application development, and members hope, by 2017, to bring to market a thermoplastic composite fuselage and torsion-box concept that proves the viability of thermoplastics in commercial aerostructures. In addition to Airbus, the TAPAS consortium includes project lead Fokker Aerostructures (Hoogeveen), the Airborne Technology Center and Kok & Van Engelen (both based in The Hague), Dutch Thermoplastic Components (Alkmaar), Technobis Fibre Technologies (Uitgeest), TenCate Advanced Composites (Nijverdal), KE-works, CoDeT and Technische Universiteit Delft (all based in Delft), the University of Twente (Enschede) and the National Aerospace Laboratory, in Amsterdam (www.tapasproject.nl/en). Dutch Thermoplastic Components, Kok & Van Engelen, National Aero- space Laboratory, TenCate Advanced Composites and VIRO (Hengelo, The Netherlands) are collaborating in the European Thermoplastic Automotive Composites consortium (eTAC, www.etac.info ; see "Learn More," p. 43). Machinery manufacturer Pinette Emidecau (Chalon-sur-Saône, France) is part of a four-company consortium that is combining technologies to provide automated, high-speed resin transfer molding (RTM) production technology. Under the name Global RTM, headquartered in Bellignat, France, the multi-faceted supplier will build and market turnkey production systems, drawing on the expertise of its three other France-based partners: toolmaker Compose (Bellignat), injection systems specialist Isojet Equip- ments (Lyon) and process control/monitoring specialist S.I.S.E. (Oyonnax). The goal is to supply turnkey systems capable of producing up to 150,000 parts per year (www.globalrtm.net). A four-year project, called WALiD (Wind Blade Using Cost-Efective Advanced Composite Light-Weight Design), partly funded by the European Commission under the 7 th Framework Programme, proposes to combine process, material and design innovations and introduce a thermoplastic composite wind blade for large, ofshore wind turbine installations. The WALiD consortium, which will commit a total of €5.1 million (US$5.4 million) to the project, comprises 11 European organizations, including, from Germany, the Fraunhofer Institute for Chemical Technology (ICT, Pfnztal) and Windrad Engineering GmbH (Bad Doberan); from the UK, Smithers Rapra and Smithers Pira Ltd. (Shrewesbury); from The Nether- lands, TNO Netherlands Organisation for Applied Scientifc Research (The Hague), PPG Industries Fibre Glass BV (Westerbroek) and NEN (Delft); from France, Loiretech SAS, Mauves sur Loire) and Coriolis Composites SAS (Queven); as well as the following: APT Archimedes Polymer Technologies (Cyprus), Norner AS (Stathelle, Norway), and Comfl ApS (Gjern, Denmark).

The Lightweight Integrated Process Application (LIPA) project, envi- sioned by Georg Kaufmann Tech-Center AG (GK-Tech-Center, Busslingen, Switzerland) seeks to develop a process of forming and "back injecting" thermoplastic prepregs or commingled thermoplastic fabrics, which the group calls "organic sheets," to produce fber-reinforced, lightweight ther- moplastic components for eventual series production. The multi-company consortium includes GK-Tech-Center and Swiss partners ASE Industrie- automation GmbH (Näfels), Kistler Instrumente AG (Winterthur), Krelus AG (Oberentfelden) and Quadrant Plastic Composites AG (Lenzburg). The consortium has constructed a specially designed, fexible manufacturing cell at its new LIPA Development Center, in Busslingen; www.lipa-series. com/en/lipa-project. The aim of the Stellar Project is to develop a manufacturing process for high-speed placement of carbon, glass and polymer fber-reinforced matrices, in selected locations in a composite structure. The project will focus on development of automated tape laying (ATL) to selectively place reinforced thermoplastic tapes in three manufacturing modes: Selective reinforcement of existing components; direct additive manufacture of components; and manufacture of selectively-reinforced tailored blanks for compression molding (http://stellar-project.eu/). Partners include NetComposites Ltd. (Chesterfeld, Derbyshire, UK), Toyota Motor Europe (Zaventem, Belgium), Airborne Development BV (The Hague, The Netherlands), HBW-Gubesch Thermoforming GmbH (formerly Jacob Plastics GmbH, Wilhelmsdorf, Germany), AFPT GmbH (Dörth, Germany), CGTech Ltd. (London, UK), ESI Group (Mérignac, France), Kunststof Technik Leoben (Leoben, Austria) and Fraunhofer IPT (Aachen, Germany). North Thin Ply Technology (NTPT, Penthalaz-Cossonay, Switzerland) has started a new research project on toughened thin-ply composites for aerospace applications, called TPCA, a two-year study. TPCA is partially funded by the Commission for Technology and Innovation (CTI) of the Swiss Confederation. NTPT joins forces with partners Huntsman (Salt Lake City, Utah and Basel, Switzerland), the Ecole Polytechnique Fédérale de Lausanne (EPFL), the University of Applied Sciences Northwestern Switzerland (FHNW), RUAG Aerostructures (Bern, Switzerland), and Decision SA (Ecublens, Switzerland). The goal of this research is to improve the toughness of thin-ply composites in order to meet or exceed aerospace requirements.
