JEC Group have brought together the international community of composites leaders and executives in our Composites Circle as an unique networking opportunity to meet with both peers and future partners.
JEC Europe 2013 - Henkel’s innovative Loctite EA 9845 lightning strike surfacing film enables the use of out-of-autoclave processing without re-work and can be cured using vacuum pressure only. The new film is 30% lighter than existing surfacing films.
This surfacing film gives a high quality of surface finish even at the lower weight and with vacuum-only processing. This reduces the weight of the structure, leading to reduced fuel consumption and emissions.Out-of-autoclave processing is a very effective way of reducing the manufacturing cost of aircraft structures, but previous lightning strike materials required full autoclave pressure to create high-quality parts and an acceptable surface finish.Aircraft external composite structures require the use of surfacing and lightning strike materials. The increased use of composites in aircraft components means a growing need for cost-effective, low-weight solutions. Henkel and Bombardier worked cooperatively in the process development of the Loctite EA9845 lightning strike film to ensure the manufacture of components with high-quality surface finish. This included scale-up of processing from the manufacture of test panels to full-scale demonstration articles. The lightning strike film is to be specified for the manufacture of fuselage components on the Learjet 85 aircraft which is going into flight testing.More information:www.henkel.comBooth R45
