Haydale has launched a graphene-enhanced prepreg to prevent lightning strikes. The material uses functionalized nanomaterials to increase electrical conductivity.
The material was developed in cooperation with Airbus (UK), BAE Systems, GE Aviation, and Element Materials Technology Warwick, and was supported by the GraCELs 2 project of the British National Aerospace Exploration Program (NATEP). The project has completed the development of the first batch of materials and conducted lightning test. The development of materials aims to establish standards for the production of composite materials. The above-mentioned consortiums are using these materials to produce sample parts for commercial exhibits.
The prepreg can realize the production of a new generation of carbon fiber reinforced composite materials, and can improve the conductivity of the material. These materials can be used as structural composite materials, and can also be used as shells for avionics systems.
The material has application potential in the fields of drones, commercial aviation and aerospace. This technology can also be applied to wind power blades, especially offshore wind power blades that are vulnerable to lightning strikes.
Conductive masterbatches are available on the market, and the Haydale team has been working with customers to test whether they can achieve significant results on existing materials.
Keith Broadbent, CEO of Haydale, said: "We are very pleased to develop this highly anticipated product and look forward to cooperating in the aerospace industry field to witness this product being available on the market. For the needs of the industry, we have worked closely with authoritative design agencies and Airbus. "
