THERMAL PROPERTY OF SILICON CARBIDE USED AS THERMAL LAYER OF WIND TURBINE BLADE MOLD

Abstract

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
