3B's SE3030 glass roving has been recognised through a JEC Innovation Award for its enhanced fibre/resin adhesion.
The roving has an optimised sizing, resulting in improved composite properties that ensure long-lasting blade operations. 3B explains that in order to offer competitive products to the market, wind turbine manufacturers need blades with low weight, high stiffness, and excellent resistance to fatigue, enabling a long and efficient working life.
According to 3B, a new-to-the-world composite system is being evaluated by Siemens Wind Power for its next generation wind turbine blades. This system was introduced by DSM and 3B, with support from DTU Wind Energy and offers easy resin infusion and processing, and excellent fibre/ resin interaction yielding superior static and fatigue strengths.
It says the system is based on DSM’s Beyone 201-A-01, a resin that is styrene-free, cobalt-free and 40 % bio based with performance that can compete with traditional epoxy systems. These enhanced performances are obtained when used in combination with 3B’s SE3030 glass fibres.
3B claims that the new composite system provides many benefits to wind turbine manufacturers including a major reduction in blade manufacturing cost, a better working environment, an increased process output thanks to significantly shorter cycle times and a sustainable material solution.
Luc Peters, 3B Wind Energy Technical Leader, comments “The use of 3B SE3030 roving optimized for styrene free resin is delivering enhanced performance versus commercially available sizing.”
“The optimisation of this sizing has been achieved thanks to an open technical exchange and brainstorming between the resin experts from DSM and the sizing developers from 3B. This also illustrates 3B’s innovative approach: build on our expertise to develop new glass and new sizing technologies to design better value, greener and higher performance solutions in close partnerships with our customers.”
“With the support of renowned labs such as DTU (Risoe) and industrial partners such as Siemens Wind Power, we made sure we were on the right track during the whole development phase. The outcome is a unique green system that was unthinkable a couple of years ago.”
Composite products, based on polyurethane technologies from global chemical company Huntsman, are taking centre stage at a design exhibition at the Design Museum Gent, Belgium.
In late November, the 14 project partners in the MoPaHyb consortium developing a modular production plant for hybrid high-performance components wrapped up their successful efforts with a two-day symposium in Pfinztal, Germany.
Alvant says its aluminium matrix composite is proven to offer significant weight and performance benefits for rotor applications found in electric motors, flywheels, fans and turbines.
