Hexcel customer Corima has won a JEC innovation award for a new concept all-carbon fibre bike wheel. The AERO+ MCC is a 100% carbon fibre wheel for road bikes produced using a complete composite process.
The rim is made of UD and taffeta weave carbon prepreg (Hexcel) wrapped on a Rohacell foam (Evonik). The hub is partly made of prepreg carbon fibres and the spokes are totally made of carbon prepreg fibres. Some parts are overmoulded and others are adhesive bonded with a structural epoxy adhesive (3M). A very high performance wheel is thus produced offering:
The result is a very high performance wheel that weighs in at only 1,000 grams for a pair.The low density of carbon fibre in the prepreg is a significant advantage, ensuring a very accurate weight distribution and a very light rim with good rotation inertia. Very high levels of stiffness are achieved, enhancing performance and the mechanical properties of the UD carbon prepreg make it possible to use only 12 spokes for both the front and rear wheels, making this a unique aerodynamic design.
The Aero+ MCC took two and a half years to develop and will be launched onto the market in May 2010 after the manufacturing processes were finalized at the beginning of December 2009.
Other finalists in the Sports and Leisure category were:
▪ A fishing rod using the 3M Matrix Resin, presented by 3M Company (USA) with its partner G. Loomis, Inc. (USA).
▪ A mountain spring, presented by AlpControl (France) with its partner Sotira (France)
▪ Composite riggings for race sailing boats, presented by Carbo-Link (Switzerland) with its partners Team Alinghi SA (Switzerland); Huntsman Advanced Materials (GmbH) Switzerland; EMPA (Switzerland) (mechanical characterization).
▪ Samsonite Cosmolite suitcases using Curv technology, presented by Samsonite Europe N.V. (Belgium) with its partners Katholieke Universiteit Leuven (Department of Metallurgy and Materials Engineering); Propex Fabrics GmbH (Germany).
Solvay has signed a ten-year agreement for the supply of composites and adhesives to be used across Bell's military and commercial rotorcraft programmes, including the Bell 429, 407, 505, 525, V-22, and UH-1.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
With the aim developing a broader platform for additive manufacturing (AM) technologies, the University of Exeter, UK, and Victrex, have formed a strategic partnership to introduce next-generation polyaryletherketone (PAEK) polymers and composites while improving the performance of the underlying AM processes.
