Abstract: With the increasing scale of wind turbine blades, wind turbine blade lightweight is also concerned. As the main component of wind turbine blades, the weight control of shear web also has a great influence on the weight of blades. Aiming at the weight problem of shear webs of large wind turbine blades, the influence of different ways of grooved webs on weight and mechanics was studied to carry out process evaluation, mechanical evaluation and product weight evaluation in depth. The results show that the machining methods of sandwich materials with different grooves and holes have less influence on the mechanics of wind turbine blade webs and less influence on the process property, but have greater influence on the weight reduction of wind turbine blades, which is of great significance to the structural design of lightweight wind turbine blades.

Key words: wind turbine blades; shear web sandwich; the way of the grooves and holes; mechanical property;weight; composites
