Summary
From a technical point of view, the overall objective of the project relates to the development of material- and design-optimised pole systems for the energy supply and telecommunications sectors.
The production of the durable material, laminated veneer lumber (LVL) from beech and coniferous wood, was to begin on a laboratory scale and be transferred to an industrial scale via pilot plants at Göttingen University. This procedure should first be carried out on defect-free test specimens with subsequent outdoor tests on test fields.
Results:
- According to initial calculations, the development of hollow mast profiles made of LVL makes it possible to save an unneeded interior timber volume of approx. 50 percent. The development of such hollow mast profiles results in considerable cost savings, including the aforementioned material savings, as only the material volume that is statically/constructively required is selected.
- By developing a joining/connection technique based on mechanical effects, it should also be possible for the hollow mast segments to be permanently joined and connected to each other in a force-fit manner.
- For the successful implementation of the project results, the further development of the technical solutions and the industrial implementation and production of poles made of phenolic resin-modified material are particularly important.
However, due to the difficulties in the industrial implementation of the production of phenolic resin-modified beech-LVL after the end of the project, the scientific and economic connectivity is to be classified as long-term.
