3B obtains GL approval for new single-end rovings

New boron-free E-CR glass single-end rovings are intended for non-crimp fabrics used in wind blade production.

3B-the fibreglass company (Battice, Belgium) has obtained Germanischer Lloyd (GL) approval for its newly developed SE2020 single-end rovings used mainly for the manufacturing of non-crimp 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-crimp fabrics made 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 offer a higher level of fatigue performance, as well as superior inter-fiber and interlaminar shear strength, constituting a key solution for designers who need to develop the next generation of wind turbine blades.”

“Sustainable wind energy 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 (in accordance with ASTM D578 and ISO 2078) 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.”
