Motivation
Work packages in the EU project GREEN-LOOP
Global consumption of biomass, fossil fuels, metals and minerals is set to double over the next 40 years. At the same time, the annual quantity of waste will increase by 70 % by 2050. This creates the need to develop high-quality products and services that are sustainable and produced using renewable materials. Climate neutrality is to be achieved through a circular economy. Newly developed technologies should help to boost the efficiency of processes and conserve energy during production.
Objectives
Schematic illustration of a plain bearing component to be developed from a wood fiber reinforced biocomposite
The primary objective is the production of sustainable bio-based composites in closed and cost-efficient process cycles, substituting conventional materials. Only natural raw materials will be used for the development. The manufactured products will be recyclable. At the HTL, a so-called Wood Composite (WC) material for sliding bearings is to be developed, which is sufficiently pressure-resistant and has a coefficient of friction < 0.3 and a wear coefficient of approx. 10-4 mm³/(Nm).
Approach
GREEN-LOOP: Flow Chart Manufacturing Process of Wood Composites (FHF)
At the HTL, experimental samples and prototype components for tribological testing at Fraunhofer IWM and LABRENTA will be manufactured by the extrusion of compounds.
- Selection and examination of biopolymers, wood fibers and tribologically effective additives
- Development and commissioning of an extruder with innovative microwave curing and sensor technology for process monitoring
- Processing of newly developed compounds to WC by extrusion and process optimization
- Optimization of properties for sliding bearing applications by variation of additives
- Examination of the recyclability of the developed WCs
