Description

SPABOND™ 820HTA and SPABOND™ 840HTA wind turbine rotor blade adhesives are toughened with 0.5 mm thick PEI and PVDF thermoplastic interlayers and their plain strain fracture toughness is determined through single-edge-notch bending (SENB) experiments. The interlayers are positioned far (6.75 mm) from the initial notch to evaluate the unstable crack-arresting capability of the thermoplastic interlayers. The raw force-displacement datasets from pristine and thermoplastic interlayered SENB experiments are provided. The typical fracture behavior of interlayered specimens is recorded using a high-speed camera, and the corresponding videos are available here.
