Gurit Launches SparPreg Featuring Airstream Technology

06 June 2012

Gurit has launched SparPreg featuring Airstream Technology, during Wind Power 2012, Atlanta, US, 3rd June – 6th June 2012.

According to Gurit, 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. They say 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.

Gurit explains the main benefits include:

  • Excellenthandling 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."
