Concordia researchers use 4D printing of composites to produce wind turbine blades on flat molds

Researchers at Concordia University have developed an inverse 4D printing of composites method for producing curved vertical-axis wind turbine blades from carbon fiber-reinforced epoxy. The process forms the blades on a flat mold, removing the need for tooling that matches the final curved geometry. The method, detailed in Polymer Composites by Emad Fakhimi and Suong…
