Fractographic analysis of sandwich panels in a composite wind turbine blade using optical microscopy and X-ray computed tomography - ScienceDirect

Fractographic analysis of sandwich panels in a composite wind turbine blade using optical microscopy and X-ray computed tomography - ScienceDirect: This study provides a new perspective on the failure of sandwich panels in a composite wind turbine blade. Fractographic characteristics of fracture regions are examined thoroughly using optical microscopy and X-ray computed tomography. The detailed fractographic analysis leads to the identification of the failure modes and failure sequence. This study addresses an important but rarely studied failure process in the sandwich panels cored with grooved foams....
