Jushi 398 on E6 glass fibres is equal to this benchmark. For polyester resin systems, Jushi developed the 386T direct roving, which is also based on E6 glass fibre and coated with a proprietary silane-based sizing. This product is also designed for weaving of UD, biaxial or multiaxial woven fabrics and offers excellent weaving performance. 386T Fig. 3: Advanced delivers excellent mechanical properties and is suitable for technologies and the vacuum-assisted resin infusion process. This new highequipment to achieve strength glass roving is particularly suitable for the clean production and improve reinforcement of areas under intense stress in large blades. ergonomics Several major wind-blade manufacturers and research institutes in China, India and Europe are beginning to use engineering team took clean production objectives fully into the E6 glass-fibre reinforcing fabrics (Figure 2). account. They adopted more scientifically sound production technology and processes to enhance product performance, while significantly reducing pollutant emissions to minimize Jushi’s environmental footprint. The development of E6 glass fibre is consistent with the company’s commitment to social responsibility and sustainability. “Jushi Group developed the E6 glass fibre and the sizing technology specifically to manufacture wind blades with improved bonding between glass and resin, resulting in enhanced fatigue resistance. With E6 glass fibre, we can help our wind energy customers in China and worldwide to develop more cost-effective products while jointly promoting the progress of the wind power industry and the development of the green renewable-energy market,” said Mr. Zhang Yuqiang, President of Jushi Group, recipient Fig. 2: Modern commercial production of multiaxial fabrics of the prestigious 2009 Forbes “Best CEO of Public for European wind-blade customers Companies in China” Award.
