Sparpreg™

SparPreg™ is an advanced diuron-free UD prepreg, developed to enable to economic manufacture of unidirectional spar caps for more demanding spar designs. SparPreg™ is specifically formulated to produce low void content unidirectional prepreg from vacuum bag only processing.

WE 91-1 / WE 91-2

The WE91 diuron-free prepreg product range comprises of two tack variants; WE91-1 high tack and WE91-2 medium tack prepregs. WE91 is a high flow epoxy prepreg ideally suited to structural composite component manufacture. 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. All of this can be achieved together with an out-life of 60 days at 21°C. WE91-2 isdesigned for vacuum bag processing and offers excellent mechanical performance on glass and carbon fibre reinforcements.

WE 92

WE 92 is a high flow, diuron-free epoxy prepreg ideally suited to the manufacture of thick sections. 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. All of this can be achieved together with an out-life of 60 days at 21°C.

WT 93

WT 93 is a diuron-free SPRINT™ resin system that 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. All of this can be achieved together with an out-life of 21 days at 21°C. WT 93 is designed for vacuum bag processing and offers excellent mechanical performance on glass and carbon fibre reinforcements.

Gurit’s innovative WT 93 SPRINT™ product range uses a high flow, low tack epoxy prepreg and is ideally suited to the manufacture of thick sections such as turbine blade roots or spars.
