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。
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-temperature 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 10^10Pa（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.
