Gurit, a world-wide leading supplier of composite materials, structural engineering and composite processing for the global Wind Energy market, launched SparPreg featuring Airstream

SparPreg™ featuring Airstream™ coating technology is a specialised prepreg developed to enable the economic manufacture of high quality UD spar caps using advanced glass and carbon fibres. Airstream™ products address the fundamental problem of creating a very high quality, low void content laminate without the use of expensive automated equipment or a temperature controlled environment. With fast deposition rates and no requirement for intermediate de-bulking steps, glass and carbon prepreg technology is now readily accessible for all wind turbine blade manufacturers.


Main benefits include:

  • Excellent handling and mould conformance characteristics from 15 to 35°C
  • Extremely low void content in any thickness without the need for cold lay-up or de-bulking
  • Low exotherm resin matrix enabling low Tg infusion grade tooling
  • Suitable for manual, automated and semi-automated lay-up
  • Available for glass or carbon unidirectional SparPreg™
  • High mechanical performance


Damian Bannister, Director Innovation Products and Solutions at Gurit comments, “Airstream™ coating technology further reduces the barriers for using high performance prepreg as a component manufacturing technology and enables our customers to design new advanced blades with confidence that the required manufacturing solutions are available.”


Gurit will also be showcasing its recent product innovations including Velinox™ a new resin system developed as a next-generation resin platform to enhance Gurit’s current wind energy prepreg and SparPreg™ products, ideally suited to benefit the cure of thick laminate sections, such as wind turbine blade spars and roots. Gurit will also be displaying its extended core offering for the wind energy market, which includes Corecell™, G-PET, PVCell® and Balsaflex® and updates to the RENUVO™ product range.
