Abstract

The invention discloses a core material structure. The core material structure comprises a main body and grooves distributed in the main body, wherein the grooves comprise at least one first groove which is formed in the first surface of the main body and extends in the length direction of the fan blade; and the at least one second groove is formed in the first surface of the main body and extends in the chordwise direction of the fan blade.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a core material structure and a fan blade. Background technique [0002] The wind turbine blade is the key component in the wind turbine. The key components are the main beam, the trailing edge beam, the web and the shell. The shell is a sandwich structure composed of core material and upper and lower skins. The proportion is the largest, and the core material in the sandwich structure is one of the key materials of the fan blade. [0003] In the process of manufacturing wind turbine blades, in order to ensure the infusion effect of the core material and improve its mechanical properties, it is usually necessary to perform processing such as slotting and punching, so that the resin can smoothly flow in it during the infusion process, and The skins laid on the upper and lower surfaces are infiltrated, and after co-curing, a sandwich structure with significantly impr...
