摘要：
The microcrack on the edge of MW wind turbine blade specimen was tested by tensile fracture test. The infrared thermography was used to monitor surface temperature of blade specimen, and research the temperature field variation in microcrack area of composite blade, and analyze the specimen damage evolution during tensile fracture of blade specimen. The results show that the heat dissipation factor of plastic energy converted into heat is 80%. The temperature change of microcrack tip firstly is linear temperature drop, then temperature rise. The test find that the specimen temperature field has no obvious change before fracture. The fracture damage form of the specimen has fiber breakage, delamination and interface debonding. © 2019, Editorial Board of Acta Energiae Solaris Sinica. All right reserved.
