Introduction
SparPreg™ is an advanced UD prepreg, developed to enable the economic manufacture of unidirectional spar caps for
more demanding blade designs, ideal for use in conjunction with other Gurit products.
SparPreg™ was developed to benefit the lay-up of thick UD sections, such as
wind turbine blade spars. The material can produce thick laminates of
exceptional quality with low void content, without the need for an intermediary
debulking process or additional dry fabric reinforcement to aid air removal. The
net result enables blade manufacturers to eliminate production steps and
redundant materials and increase capacity.
SparPreg™ has been specially formulated to achieve the outstanding in-cure
®
and mechanical performance of the SE91 prepreg and ST93 SPRINT resin
systems.
SparPreg™ can be cured at temperatures as low as 85°C, but can also be used
for the rapid manufacture of components at 120°C.
SparPreg™ is also available with Airstream™ Coating Technology – to
eliminate air conditioning without compromising laminate quality
