PDSWE-SparPreg-4-0309 1 SparPreg™ UD Prepreg for SPRINT®-quality Blade Spars and Roots n UD prepreg ideal for use in thick sections n Potential elimination of debulking/dry fabric production step n Increased productivity, reduced weight & cost for manufacturers n Excellent processing properties during lamination n Fully compatible with current SPRINT®/prepreg products n Excellent mechanical properties n Recommended cure between 85ºC and 120ºC n Out-of-autoclave curing n Diuron-free chemistry Introduction SparPreg™ is an innovative UD prepreg, developed to compliment the current WE and WT range of prepreg, and SPRINT®, products. This unique prepreg provides technically and commercially competitive engineering materials, ideal for use in conjunction with other Gurit products. SparPreg™ was particularly developed to benefit the lay-up of thick UD sections, such as wind turbine blade spars and roots. 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 manufacturer to eliminate production steps, redundant materials and increase capacity. SparPreg™ has been specially formulated to achieve the outstanding in-cure and mechanical performance of the WE91 prepreg and WT93 SPRINT® systems. It is designed for vacuum bag processing and can be used with glass and carbon fibre unidirectional reinforcements. 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.
