HiPer-tex™ W2020 Rovings are specifically designed to provide significantly higher modulus, strength and enhanced fatigue performances versus traditional E glass for wind turbine epoxy blades. HiPer-tex™ W2020 Rovings are perfectly suited for the production of high modulus Non Crimped Glass Fabrics and prepregs. The sizing W2020 is purposely formulated for excellent adhesion with epoxy resin systems and leads to superior inter fibre and interlaminar shear strengths as well as dynamic performances. The specific boron-free glass formulation provides superior hydrolysis and corrosion resistance. These properties' improvements versus typical E-glass will help blade designers to push further the limits of glass fiber blade designs, especially for the long blades required for the multi-MW turbines for on-shore and off-shore. The W2020 roving is approved by Germanischer Lloyd for the use in wind-turbine rotor blades.

HiPer-tex™ reinforcement is a non-added boron glass which can be classified as high strength R-glass, as defined by the ASTM C-162, DIN 1259 and ISO 2078 standards. This glass formulation is designed for high modulus, excellent mechanical properties and to offer significantly better thermal and corrosion resistance properties than E-glass.

Main benefits of HiPer-tex™ fibre versus E-glass are:

• up to 30% higher strength

• up to 17% higher modulus

• up to 45% higher strain energy

• up to 10 times improved lifetime in fatigue

Product line includes reinforcements developed for end applications such as wind turbine blades, composite ballistic panels, sport goods as well as high pressure vessels. Our dedicated Technical and Sales team would be looking forward to working on your applications.
