Lightweight construction, as a key element for sustainable transport, is experiencing massive resistance in shipbuilding due to inadequate joining technologies for fibre composite materials and steel. With the funded research project “Hybrid joining technology for joints in maritime applications”, acronym HyFiVE, five industrial companies and three scientific institutions will develop new technologies and evaluate them for maritime applications.

Coordinated by SAERTEX GmbH & Co. KG, adhesive-free joining technologies for maritime use are developed over a period of three years. Bonding, as the state-of-the-art process for joining lightweight structures from fibre-reinforced polymers (FRP) and metal structures, often does not meet the time and cost requirements of shipbuilding production in terms of design, certification and production. Therefore, the aim is to develop new and efficient adhesive-free joining technologies for FRP and metal applications.
Different approaches to maritime requirements will be evaluated and developed in the consortium along the entire value chain. The partners in the project cover the entire spectrum from textile and material manufacturers, engineering offices to manufacturing companies. They are supported by three scientific institutions with their expertise in the field of fibre and fibre reinforced polymer technology as well as in the field of welding.
Focus on the shipbuilding application
An essential aspect of the project is the development of the technologies along the requirements in shipbuilding. This includes the integration into FRP components by means of different manufacturing methods, scalability, non-destructive testing, as well as the behaviour and protection against fire. For this purpose, the consortium will work closely with shipyards and classification societies.
Further information on the project will be available soon at
