Blade Materials Manufacturing and Testing

The Blade Materials Manufacturing and Testing section is advancing wind turbine blade technologies through a research strategy that combines predictive modeling, multi-scale material characterization, and pathways for industrialization.

Our focus lies in predictive modeling for manufacturing, enabling high-fidelity simulations of composite behavior throughout key processing stages such as resin infusion and curing. On the testing front, the section advances finite element optimization of test coupons, significantly improving the reliability and efficiency of both material and structural evaluations. Research also targets length-scale bridging, linking fiber-scale understanding to full-scale blade performance, thereby enhancing the accuracy of test predictions. 

Another strategic priority is the acceleration of material qualification and manufacturing processes, aimed at reducing the time-to-market for novel blade designs and materials. In parallel, the section is committed to sustainable innovation, with ongoing efforts in recyclable composite materials, waste reduction, and decommissioning strategies that support the green transition in wind energy. 

The section hosts two specialized labs and organizes their overall QHSE and operational efficiency. MaterialsLab focuses on validating composite properties and damage mechanisms under ISO 17025, while ComponentLab supports blade manufacturing and industrialization through sensing technologies, scalable molds, and full-scale IEC-compliant testing. More details on the labs are available on the facility pages. 

Together, these capabilities enable a seamless transition from fundamental research to industrial application, supporting the development of high-performance, reliable, and sustainable wind turbine blades.
