2007, Gurit launched their first automotive composite part production facility to supply the Aston Martin DBS with the leading technology in carbon composite body panels. The elusive objective of all composite panel manufacturers has been to reach an A-Class surface directly from the tool. Aeronautics: PB1000 is a modified benzoxazine resin without free formaldehyde and free phenol for aircraft interior prepregs. It satisfies the most recent environmental standards like the Airbus AP2091 standard. It features a non-volatile, rapid cure which generates a perfect void- and porous-free surface, while eliminating time- and cost-consuming rework. This novel resin fully complies with demanding international JAR/FAR fire protection regulations. Gurit also introduced its advanced range of unidirectional carbon fibre EP137-CR527 prepregs for the Airbus A380 passenger floor. Perfectly suitable for lightweight composite panels, they meet the highest requirements for structural interior applications while meeting increasingly cost-saving demands. These prepregs are especially designed for automated lay-up processing. Marine: SP540 PB and SP540 LV are high-performance modified epoxy adhesives designed for bonding large production boats. The adhesives are formulated to bond polyester, are easy to use, have increased working times, and consistently provide a high strength and durable bond to a variety of substrates in the production environment. SP540 LV is designed specifically for builders of polyester GRP boats, allowing greater flexibility of application and a working time up to six hours – ideal for an industry facing the technical challenges of bonding the hulls of increasingly large production boats. The Ampreg 21 has been optimised for the manufacture of large composite structures using hand lay-up and vacuum bagging techniques. Its relatively low initial mixed viscosity allows easy wet-out of heavyweight reinforcements and has been formulated to offer a good health and safety product. www.gurit.com New coating and barrier technologies Cray Valley and CCP introduced the Imedge™ technology in Europe at the JEC Show. These innovative polymer coating technologies (PCT) and polymer barrier technologies (PBT) have been developed to push the composite industry beyond the limits of conventional in-mould products. Market analysis and an extensive discovery process with numerous composite manufacturers revealed two opportunities for significantly new coating and barrier technologies in the composite industry. The first opportunity was for coating technologies providing significantly improved crack resistance in comparison to conventional gelcoat and barrier coat products. The second opportunity was for a deeply coloured coating that could be restored to its initial colour and gloss when repaired. The new Imedge series now responds to these needs and will be soon inaugurated in Europe via two breakthrough products: (1) the Imedge PCT100 Series, which features deep, rich, lasting colours with maximum resistance to blisters and fading, higher abrasion resistance, while also sharply improving patch and gloss recovery, and (2) the Imedge PBT200 Series, a toughened barrier coat that exponentially improves resistance to cracking and chipping both in-process and during consumer use, while providing enhanced blister resistance. Some process modifications may be required to apply these new products, but the application is similar to conventional gelcoats and barrier coats. www.crayvalley.com JEC Composites Magazine / No41 June 2008
