Development of thermo-hygro-mechanical processes and a machine implementation for the bending forming of compressed resin-wood into technical profiles.

Thin-walled technical profiles, especially hollow sections, offer numerous advantages compared to solid components. With the same cross-sectional area, a higher moment of inertia and thus a greater load-bearing capacity can be achieved. In terms of load-bearing capacity, components with technical cross-sections are generally lighter than solid cross-sections. Hollow sections, as well as shell sections, can also be used for the transport of solid, liquid, and gaseous media. The project aims to develop rod-shaped structural elements with hollow or profile cross-sections made from compressed resin-wood (KHP), as well as a prototype forming device. The following sub-tasks need to be addressed: development of an efficient manufacturing concept for wood hollow profiles made from KHP, creation of a prototype forming device, development of impregnation processes to ensure dimensional stability during the impregnation and curing process, and testing of mechanical and hygric properties. The project goal is to create a small-scale, marketable profile made from KHP, which can be connected using connecting elements made from KHP, plastic, or metal connectors.
