竹丝炭化时间对风力发电机叶片阻燃性能的影响.pdfVIP

* 黄晓东 江泽慧 孙正军 () : 风力发电站常常安装在偏远的海岛高山或沙漠地区, 叶 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 材料阻燃性能的选择就显得十分重要采用HRR 热释放率系统H C- 2 氧 3 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 10 m in 炭化处理制造的竹增强复合材料, 试件在 HRR 热释放率系统测试实验中产生的热释放量峰值最低 3 2 2 ( 9944 kW /m ), 且在 5 m in 内总热释放量最低( 339. 15 kWm in /m ), 氧指数值最高( 52), 其阻燃性能较好 : 竹丝; 炭化时间; 风力发电机叶 ; 复合材料; 阻燃性能 Effects ofHeat-treatment Time on the Flame-Retardant Properties ofW ind Turbine Bio-bladesMade from Bamboo ThreadHUANG X ia -d ng, JIANG Ze-hui, SUN Zheng-jun Abstract: The w ind turb ines usually fixed n rem te is lands, h igh m un tains, and desert areas.
