摘 要:
利用动态热机械分析仪检测不同竹龄的毛竹,实验证明:在常温条件下,毛竹竹青的刚性随毛竹竹龄的增加而增加,当毛竹到了一定竹龄后,其竹青的刚性渐渐趋于稳定。一般5~6年生的成熟毛竹的竹青部分的常温存储模量位于10~(10)Pa(10GPa)数量级以上,一般能满足做为风力发电叶片复合材料中增强相材料的使用。因此,最佳的风力发电叶片复合材料增强相材料是5~6年生的成熟毛竹。

摘 要:
The bamboo samples of various ages were tested by a Q800 dynamic mechanical thermal analysis (DMA)instrument.The results showed that the storage modulus of the outer layer of bamboo under air-tempera- ture conditions increased with the aging of bamboo,i.e.,the stiffness of bamboo increased with the increasing age of bamboo.However,up to a certain age,the stiffness of the outer layer of bamboo gradually remains constant. General speaking,the outer layer of 5~6 year-old bamboo has a storage modulus on the order of 10~(10)Pa(10GPa) under air-temperature conditions,which is definitely qualified as the reinforcement material for the wind turbine blades composites.Therefore,the out layers of bamboo of 5~6 year-old showed great potential to be used as the reinforcement materials of the wind turbine blades composite.
