| 摘 要： | 为开发风能作为全球的新能源,针对目前风电玻璃钢叶片存在问题,对分级杉木作风电叶片复合材料增强相的可行性进行了研究。结果表明:由一、二级分级杉木制成的风电叶片复合材料,其最大拉伸强度和最大压缩强度,均达到或超过目前国外使用的常规木材/环氧层积材风电叶片材料,完全能够替代玻璃钢叶片材料而大量使用。 |

| Abstract: | 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. |
