Because petroleum and coal,as primary energy resources,are diminishing and cause pollution and environmental problems,wind energy will provide a sustainable and green alternative to the increasing world demand for energy.Traditional fiberglass-reinforced plastic (FRP),which is primarily used to make wind blades,faces some challenges such as sustainability,cost,and disposal. In this study,the feasibility of utilizing Cunninghamia lanceolata to make wind turbine blades was investigated. The results showed that the maximum tensile strength of wind turbine blades,along its grain direction,was 123 MPa and its maximum compression strength was 82 MPa.Their mechanical performance was equivalent to,or exceeded,the commonly-used wood/epoxy materials. The results show that the Cunninghamia lanceolata could be a potential alternative for wind blades in the future,but further research about its reliability are needed.
