SparPreg® is an innovative new UD prepreg to compliment the current WE and WT range of prepreg, SPRINT®, and AIRSTREAM™ products. This unique product range provides technically and commercially competitive engineering materials, ideal for use either solely, or in conjunction with other Gurit products from within the range.

SparPreg® is ideal for use in thick UD sections, such as wind turbine blade spars and roots. The material can produce laminates of exceptional quality with low void content, without the need for debulking or additional dry fabric reinforcement to aid air removal. This allows the blade manufacturer to increase productivity, and reduce blade weight and cost.

SparPreg® is a high flow, Diuron-free epoxy prepreg. It can be cured at temperatures as low as 85°C, but can also be used for the rapid manufacture of components through its 45-minute cure at 120°C.

SparPreg® has been specially formulated to achieve the outstanding in-cure and mechanical performance of the WE91 prepreg systems. It is designed for vacuum bag processing and can be used with glass and carbon fibre unidirectional reinforcements. The material can be manufactured in large volumes in order to make it a cost-effective composite building block for a range of applications.
