Study on Lay-Up Algorithm and Generating Technology of Large-Scale Composite Wind Turbine Blade

In order to increase its performance and quality, lay up molding method is adopted to form large-scale composite wind turbine blade. Fibre lay-up of wind turbine blades must be multi-directional lay-up because of its complexity of bearing load and multi-direction of internal stress. Lay-up algorithm is the basis of fibre mold. Lay-up algorithm and generating technology of 0°, ±45°and 90° for blade are studied in this paper, and their lay-up paths of 1.2 MW blade are generated in UG NX4.
