In the 3DWoodWind project, three-dimensional winding processes are being developed for material-efficient hollow profile lightweight components made of wood. Winding processes are known from fibre composite technology for highly stressable lightweight components for aviation. These fibre-based processes work predominantly with synthetic composite materials made of carbon or glass fibres. For the construction industry, these additive processes are very promising and resource-efficient building processes, which, however, are still hardly used in timber construction despite the very high level of digitalisation and technical development. Currently used wood filaments, for example, consist of a mixture of thermoplastic and ground wood, which means that the long fibres of naturally grown wood are no longer present and, as a result, the inherent material properties of wood such as anisotropy and structural resilience are lost. 3DWoodWind uses a continuous strip of thin veneer strips as the application material. Its natural fibres are intact, continuous and tensile. In the project, high-performance hollow profile lightweight components are to be developed. It is planned to develop a robot-assisted manufacturing process based on the DFG large-scale facility "Research Facility for Robotic Architectural Production" RAP-Lab. This production process is intended to create components by robotically applying and winding veneer strips, such as rectangular as well as free-form supports or beams. Due to their high performance, these hollow lightweight components could serve as substitutes for concrete or steel components in the future.
