分级杉木风电叶片复合材料的制备与研究

Study on the preparing wind turbine blades composite materials from grading Cunninghamia lanceolata

以杉木为原料,通过杉木分级、优选制成杉木薄板层积材,利用INSTRON 5582万能力学试验机进行检测.试验结果表明:由一、二级分级杉木制成的风电叶片复合材料的物理力学性能均达到或超过目前国外风电叶片在用的常规木材/环氧层积材的特性,完全能够替代目前大量使用的玻璃钢叶片材料.

In the paper, the laminated veneer lumber （LVL） were made from grading Cunninghamia lanceolata. The wind turbine blades composite materials were tested by INSTRON 5582. The results showed that mechanical properties of wind turbine blades composite materials made of first and second grading Cunninghamia lanceolata could met or exceeded wood / epoxy laminated used in the world. It can substitute FRP blades materials in the further.
