摘要
风力发电站常常安装在偏远的海岛、高山或沙漠地区,叶片在使用过程中常受到高温、闪电、野火等等不利因素的影响而烧损,因此,风电叶片材料阻燃性能的选择就显得十分重要。采用HRR3热释放率系统、HC-2氧指数测定仪等仪器,测定并分析经由不同炭化时间处理的竹丝制造的竹增强复合材料的阻燃性能。结果表明:竹丝经10min炭化处理制造的竹增强复合材料,试件在HRR3热释放率系统测试实验中产生的热释放量峰值最低(99.44kW/m2),且在5min内总热释放量最低(339.15kW.min/m2),氧指数值最高(52),其阻燃性能较好。
The wind turbines usually fixed on remote islands, high mountains, and desert areas. The turbine blades were easy to burn down due to high temperament,lightning, fire, For this reason, the flame-retardant properties of the material selection of the wind turbine blades play an important role in the wind turbine designs. In this study the flame-retardant properties of the bamboo strengthened composite material samples made from phenol-formaldehyde resin (PF), phenolformaldehyde and epoxy resin, epoxy resin were tested by HRRs Heat Release Rate System equipment and HC-2 oxygen index equipment, The results showed that : The best flame-retardant properties appeared when the bamboo strengthened composite material samples made from 10 minutes carbonization bamboo threads in this HRRs study,the peak of heat release rate reached the lowest,the oxygen index value was the highest,and the total heat release amount in 5 minute was the lowest.
