Abstract
Fiber-reinforced thermoplastic composites continue to be implemented in several markets
because of their strength capacity and light weight. Especially in the wind industry, wind blades
are made of this material which makes them ideal for wind energy generation, but blades
become a problem at end-of-life. Because recycling thermoplastic composites technologies
are still not cost and environmentally effective, research in this space is needed. This paper
presents a case study for coupling repurposed wind turbine blades and 3D printing technology.
The purpose is to remanufacture decommissioned wind blades into bus stop roof and seating
sections to then use recycled glass fiber from a decommissioned wind turbine blade to 3D
print structural and/or fixtures needed in the assembly. We provide an overview of the design
process, and the development process steps in repurposing and 3D printing the material,
delving into key parameters required for a successful implementation.
