Important results from the project
The new methodology to join thermoplastic composite to metal with TIG a s heat source works. The strength of the joint depends however on how the carbon fibre reinforcement is made and also on the metal coating. Since the joint strength is limited this methods is sofar mainly suitable for non-loaded applications or temporary fixturing.
Expected long term effects
In the FFI program sustainable production technology new light materials are identified as a key area. This project aimed to evaluate the possibility to use of conventional welding equipment in a novel way for joining thermoplastic composite to metal. The main conclusion is that it is possible but with some limitations both in strength and selection of materials.
Approach and implementation
The project is performed in co-operation between Swerea KIMAB, Volvo CC and Volvo LV. The role of Swerea KIMAB was to manage the project, to perform the welding and mechanical testing and evaluation of tests. The budget for Swerea KIMAB was 500 kSEK. The role of Volvo CC together with Volvo LV was to specify demands, decide conditions for the welding tests, participate in evaluate and discussion of the results and judge practical usability of the joining technique. Both Volvo CC and Volvo LV had a project budget of 100 kSEK each.
