The Dinamite project (Development of Industrial Technological Solutions for Metal/Compposite Assembly) is a collaborative resourcing project focused on the problems of assembling non-weldable materials. It brings together 6 CRTs/CTI flagships of the Industrial R&I of the Grand East: Cerfav, CIRTES, CM2T, IREPA LASER and TJFU will work on this project coordinated by the INSTITUT DE SOUDURE. The aim of the project will be to develop and develop multi-material assembly processes for metal/composite assembly as well as suitable and clean surface treatment technologies to improve assemblies, to characterise the holding of assemblies and to develop their uses for the production of multi-material parts with new functionalities, in particular by meeting needs to increase weight or reduce assembly complexity. For this purpose, the selected material pairs will exclusively target transport applications: automobile on the one hand, and aeronautical on the other.
