| Abstract: | The compressive tests and acoustic emission(AE ) response characteristics of wind turbine blade composite material were conducted.The results showed that transverse compressive properties and corresponding AE characteristics of composite material were different to longitudinal direction.High compressive strength,high modulus,low failure strain,high AE relative energy,high amplitude and less cumulative hits were obtained in longitudinal direction.Furthermore,composite specimens exhibited brittle characteristics.The main failure modes of transverse and longitudinal compression were 45°shear failure and layer splitting,respectively.The AE monitoring results such as energy,amplitude,hits and other parameters in compressive tests were useful for monitoring the damage development and failure of the specimen. |
