Abstract Scope |
Additive manufacturing methods have been investigated for use in utility scale wind turbine structures for production wind turbine blades. This talk will discuss the challenges and opportunities associated to fatigue performance needs of wind turbine structures. Fatigue performance in wind turbine blades is a critical-to-quality performance metric of wind blade structural materials. An overview of strain-controlled fatigue performance of 3D printed materials and S-N curves will be shared. Materials tested include glass reinforced PETG and also a new thermoplastic poly(hydroxy amino ether) resin reinforced with glass fiber from L&L Products. Comparisons between fatigue tests run on injection molded bars compared to 3D printed bars with the same materials will also be shared. An overview of a large scale pilot demonstration of multihead 3D printing to produce a 12 meter blade tip for structural testing will also be shared. |
