Optimizing Wind Turbine Blade Materials for Performance and Recyclability

Abstract

This study explores the optimal performance attributes (strength-to-weight ratio, fatigue resistance) of wind turbine blade materials with enhanced recyclability. Considerable challenges exist for traditional thermoset composites at the end-of-life stage. We aim to study their mechanical properties and environmental impact alongside thermoplastic composites and bio-derived materials. The approach encompasses LCA (Life Cycle Assessment) alongside material property comparisons and theoretical blade design modeling. Results indicate that achieving performance parity is possible with existing materials; however, substantial sprouts in recyclability and landfill waste reduction can be attained through innovative materials, thereby enabling a circular economy for wind energy.
