Battice, Belgium – November 29, 2012 – 3B-the fibreglass company has obtained Germanischer Lloyd (GL) approval for its newly developped SE2020 single-end rovings used mainly for the manufacturing of non-crimped fabrics used to make wind turbine blades.
“Obtaining GL certification illustrates the high quality and integrity of our SE2020 rovings and products” commented Luc Peters, 3B Wind Energy Technical Leader. “Non crimped fabrics from SE2020 rovings are suitable for resin infusion or prepreg processes and benefit from 3B’s innovative and proprietory sizing technology focused on specific resin families, in this case epoxy. The resultant laminates offers a higher level of fatigue performance, superior inter fibre and interlaminar shear strengths, constituting a key solution for designers who need to develop the next generation of wind turbine blades.”
“Wind power generation is by far the most environmentally acceptable solution toward a sustainable and pollution free energy source to help meet our needs for decades to come. However, this will require multi-megawatt turbines with bigger blades placed in very exposed locations ideal to deliver cost-effective electricity production,” commented Onur Tokgoz, 3B Wind Energy Global Business Leader. “SE2020 roving is made from a boron-free E-CR glass* offering significantly improved corrosion resistance across a wide range of aggressive environments. Coupled with enhanced composite properties, it is well-matched for optimum performance in wind turbine blades particularly offshore where operating conditions are more extreme.”
