摘要/Abstract

摘要： 采用真空灌注成型工艺制备了模拟叶片模具玻璃钢复合材料试板,利用碳化硅作为试板的导热层,研究了不同目数的碳化硅导热均匀性。结果表明,当220目碳化硅与100目碳化硅质量比为1∶1时,碳化硅导热均匀;当碳化硅/环氧树脂混合体系的黏度为2.9Pa·s时,体系具有适宜的刮腻性,适合将其作为叶片模具热容层;将碳化硅应用于叶片模具生产中时,模具表面平均温度为63℃,温度整体分布比较均匀。

关键词: 风电叶片模具, 碳化硅, 导热性能

Abstract: A type of glass fiber reinforced epoxy composite was prepared to simulate wind turbine blade using vacuum infusion molding process. Silicon carbide (SIC) was used as thermal layer in the blade. The thermal conductivity of silicon carbide granularity was studied. When the mass ratio of 220 mesh to 100 mesh silicon carbide was 1∶1, SiC exhibit uniform thermal conductivity. When the viscosity value of the SiC/epoxy system was 2.9 Pa·s, the system was able to be used as a blade mold thermal layer for its decent property of scraping. When SIC was applied to the blade mold, the average surface temperature of the mold was 63℃, and the overall temperature distribution was uniform.

Key words: wind turbine blade mold, silicon carbide, thermal conductivity
