State-Of-The-Art Models For Mechanical Performance Of Carbon-Glass Hybrid Composites In Wind Turbine Blades
41ST RISO INTERNATIONAL SYMPOSIUM ON MATERIALS SCIENCE: MATERIALS AND DESIGN FOR NEXT GENERATION WIND TURBINE BLADES(2020)
摘要
Wind turbine blades are a key growth market for fibre-hybrid composites, as they offer the potential for higher turbine efficiency at a reduced cost. This paper therefore overviews the developments of KU Leuven models for mechanical properties relevant to wind turbine blades, including fibre-hybridisation, size scaling effects, flexure, transverse cracking, stress relaxation and fatigue. The strengths and limitations of the models will be highlighted with a particular focus on relevance for wind turbine blades. While significant steps forward have been made, the various developments still need to be incorporated in one all-encompassing model, and further work is needed on gathering the required input data and detailed experimental validation studies.
