Recycled Carbon Fibers from Wind Turbine Blades: Advancing the Mechanical Performance of Concrete

Abstract Recycled carbon fibers from wind turbine blades offer a sustainable approach to enhancing concrete’s mechanical properties. This study investigates the preliminary performance of concrete reinforced with fibers recovered via pyrolysis. Experimental results demonstrate improvements in flexural strength (up to 30%) and fracture mechanics parameters (e.g., KIc and CTODc). Planned research will focus on optimizing mix designs and exploring deformation criteria for quasi-brittle materials, paving the way for environmentally friendly construction solutions.
