PRF Composite Materials were selected as suppliers of the epoxy resin system and glass roving for an innovative composite structures design and manufacturing project led by Andrew Mills at Cranfield University’s Composites Centre.
According to PRF, the NOVA project addresses the affordability of the scale up of UK offshore wind energy generation with a pioneering vertical axis wind turbine concept, also known as VAWTS. In order to investigate the affordability and practicality of manufacturing the world’s largest turbine, a 10MW machine, an Energy Technologies Institute- and EPSRC-funded feasibility study took place. A smaller scale 50KW concept demonstrator with a pair of 10m length carbon and glass fibre reinforced sails, known as APP, was designed and manufactured at Cranfield and funded by the ERDF.
PRF says the structure of these turbines, with two 160m length arms which support two 80m V-shaped sails, partly negates the horizontal load which acts to overturn the superstructure in conventional wind turbines. This means that the size required for the undersea support can be reduced, which minimises cost and improves accessibility for maintenance.
They explain how the project required a resin system that would provide a balance between long temperature curing and long gel time at room temperature. A two part epoxy resin, supplied by PRF, was chosen for this job. RS-M135 with amine type RS-MH137 hardener provided the required attributes of low viscosity (approx. 300 mPa.s), a gel time of 3-4 hours for thick sections at 22°C, and a glass transition temperature of approx. 72°C after 24 hours at 50°C.
PRF’s business development manager, Crispin Jones comments “We are delighted to be involved in this innovative project. Working with Cranfield University has enabled us to extend our commitment to renewable energy and sustainability globally, and to support the improvement of wind energy provision in the UK.”
Andrew Mills will be presenting the full project details at Composites Innovation 2012, at the National Composites Centre, 4-5 July.
Sumitomo Chemical reports that its polyethersulfone (PES) micro-powder additive SumikaExcel 5003P boosts fracture toughness and resistance to micro-cracking for fibre reinforced epoxy composites over a broad temperature range without negatively impacting dimensional stability, flame/smoke/toxicity (FST), creep resistance, modulus, impact, or yield strength.
Renault, Webasto, ARRK-Shapers and Polyscope Polymers won the People’s Choice award for the most innovative composite part at the 18th annual Automotive Composites Conference & Exhibition (ACCE) sponsored by the Society of Plastics Engineers (SPE).
ZSK will hold its bi-annual technology showcase on 21-22 September 2018 at its Krefeld, Germany, headquarters. The Embroidery Technology Show assembles more than 25 exhibitors from around the world to discuss emerging trends in the embroidery manufacturing industry and demonstrate the latest products produced using techniques such as tailored fibre placement (TFP) or smart textiles.
