Gurit shows new-gen of pre-impregnated composites at JEC
March 11, 2014 - Switzerland
Gurit, a leading global manufacturer and supplier of Composite Materials, Systems and Engineering, will be showcasing its latest product innovations and engineering capabilities at JEC Europe 2014 in Paris, from Tuesday 11th to Thursday 13th March 2014. The exhibition will be held this year in Pavilion 7.3, Porte de Versailles, and is the biggest composite exhibition in the world.
Exhibiting on stand M19, Gurit will be showcasing its most recent developments in composite materials, pre-impregnated and structural core materials. Gurit will also present a range of eye-catching exhibits along with case studies that reflect Gurit’s engineering capabilities that allow Gurit to offer a complete composite solution to its customers.
New Generation of Pre-Impregnated Materials
Gurit will be presenting its new generation of pre-impregnated materials (prepregs) that are widely used in Automotive applications and in some other demanding and high-temperature applications. This new range of prepregs provides manufacturers with composite materials designed for a variety of applications, both structural and cosmetic. The materials offer class leading performance along with the recognised benefits of composites: strength, lightness and the ability to fashion complex shapes.
The new range includes:
-SC 110 Cosmetic Carbon Prepreg
Ultra high clarity – ideal for cosmetic components with no whitewash or spots
On average a 20% increase of yield of finished parts due to the elimination of whitewash
-SC 110 Cosmetic Carbon Prepreg utilises a high clarity, versatile, hot-melt epoxy resin formulation. The unique formulation ensures that no white-wash or white spots are evident in the cured resin. It is ideal for manufacturing high visual quality components using autoclave and press processing. It can be cured at temperatures as low as 80°C, or it can be used for faster moulding of components at 120°C.
This is achieved with a good out-life of up to three weeks at 21°C. It is a toughened system, and offers excellent mechanical properties on a wide variety of reinforcing fabrics and fibres. This new carbon fibre prepreg can be used to produce components like e.g. bonnets or grills but also more complex shapes with tight curvature.
SE 200 Structural Carbon Epoxy Prepreg
Toughened Structural Carbon Epoxy Prepreg with excellent hot/wet performance Fast, flexible curing options.
SE 200 is a high strength structural carbon prepreg based on a toughened epoxy system. It has a flexible cure envelope ranging from 135°C to 200°C. SE 200 has been developed to enable rapid part manufacture through a number of composite processing methods. The minimum cure temperature is 135°C from which SE 200 develops Tg and strength properties at a level associated with high temperature 195°C curing systems.
Higher temperature cures in excess of 180°C will achieve the best dry and wet thermal performance. Using the appropriate press moulding technology it is possible to achieve a 15 minutes hot-in / hot-out cure at 195°C, making SE 200 suitable for the economic production of automotive parts.
SE 200 Structural Carbon Epoxy Prepreg can be used in the making of parts such as structural lower tubs, bulkheads, front and rear scuttles, exhaust tunnels and other structural components.
SE 300 High Tg Prepreg
High temperature stability with Superior flame retardant properties and Aerospace grade FST standards.
SE 300 is an ideal prepreg for high temperature composite applications, as it combines the ease of processing and handling convenience of epoxy resins, high temperature stability of polyimides, and flame / fire resistance of phenolics. A 120°C cure for 75 minutes combined with a post-cure, enables SE 300 to generate a Tg in excess of 300°C, making SE 300 ideal for applications in composite structures, which are exposed to very high temperatures for short durations. The flame and smoke characteristics of SE 300 composites show that this resin possesses superior flame retardant properties and holds a wide range of Aerospace grade FST (Fire/Smoke/Toxicity) standards.
