Abstract: The new BÜV-code for structural design of polymers in load bearing structures (2010-08).Fibre-reinforced polymer composites (FRP) have found a growing market in the construction sector. In special fields of application FRP offer high strength to weight ratio, excellent corrosion resistance, high thermal insulation and electrical isolation. With the BÜV-code "polymers in load bearing structures" (2010-08) a guideline for structural analysis and design of FRP is presented. Special focus is laid on the "duration … Show more

With the green energy transition, the wind industry has grown rapidly in recent decades. Wind turbine blades (WTBs) are primarily manufactured from glass fibers and thermoset matrix composites. Considering their lifetime from 20 to 25 years, significant amounts of wind turbine components will eventually enter the global waste stream. Currently, recycling is not sufficiently optimized and commercially available. Other strategies, such as repurpose, are becoming relevant to divert components from waste streams. This research explores a pathway to sustainable repurposing of decommissioned WTBs. The concept of a tiny house constructed from the root section of a 5 MW/61.5 m WTB is presented (“5 MW house”). The deformations and stresses of the repurposed composite structures were investigated using a finite element analysis based on the three load cases, defined by (1) a combination of snow load and payload, (2) a combination of wind load and payload, and (3) a thermal stress analysis of a critical temperature distribution of the 5 MW house. Furthermore, a life cycle assessment (LCA) was conducted to evaluate the environmental impacts of the proposed concept. The numerical analysis results showed that the 5 MW house can withstand the applied loads, and that the deformations are within acceptable limits. A reduction of up to 97% in environmental impacts for most impact categories was calculated, compared to a wooden tiny house, whereas climate change, ozone depletion, and eutrophication potential were up to 3.7 times higher, mainly due to the weight and composition of the 5 MW house. The authors believe that the proposed concept may be a high-volume repurposed solution for large-scale WTB root sections.
