Development of Vertical Wind Turbine Blades Using 4D Printing of Composites

Polymer Composites, EarlyView.
Vertical axis wind turbine: White blade: Commercial. Black blade: Composite. ABSTRACT This paper presents the procedure to make vertical wind turbine blades using the technique of 4D printing of composites (4DPC). The blades are made using carbon/epoxy composite materials with a fiber volume fraction of about 60%.
