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. Further, the tensile experiments of epoxies and thermoplastic are performed and the stress-strain and longitudinal strain-lateral strain data of SPABOND™ 820HTA, SPABOND™ 840HTA, Natural Kynar® PVDF and Ultem® 1000 PEI materials are provided. Also, 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.
