Research on Forming Technology of Thermoplastic Composite Blade for Wind Turbine

Abstract:

Thermoplastic composite has become preferred material for wind turbine blade with high performance, low cost and greenization. The fused mass of the thermoplastic resin has high viscosity and the forming of the thermoplastic composite materials is laborious, quality is not readily guaranteed, thus, the widespread use of thermoplastic composite blades for wind turbine is restricted. Based on the analysis of all kinds of the characteristics of thermoplastic forming technology, the paper has points out that the diaphragm forming is especially suitable for making a hyperboloid, variable thickness, large size wind turbine thermoplastic composite blade structure. The key to improving the forming quality and the efficiency of the thermoplastic blade forming is to establish finite element deformation model of a diaphragm forming process, to effectively control the process parameters such as temperature, pressure, forming rate. Conducting research on thermoplastic blade diaphragm forming technology lay the foundation for the industrialization of thermoplastic wind turbine blade.
