Abstract
A study was conducted on the change in mechanical properties due to void, one of the fabrication defects of composite materials for wind turbine blades. The study was conducted based on glass fiber fabric, which is mainly applied to wind turbine blades, and the material properties were predicted by simulating random defects with micro and meso modeling of the composite material with void. The basic properties due to void were predicted through the homogenization method, and the failure properties were obtained through progressive failure analysis by applying virtual coupons according to ASTM D3090 and ASTM D6641. The currently widely used Mori-Tanaka method was used for mean field homogenization, the Hashin theory was used for failure conditions, and the Matzenmiller-Lubliner-Taylor method was used for progressive failure.
