Abstract

The invention provides wind generating set blade core materials which comprise a core plate, wherein a main resin pouring groove is formed in the front surface of the core plate. An auxiliary resin pouring groove is formed in the back surface of the core plate, an anti-overflow layer which is laid on the back surface of the core plate is arranged above the auxiliary resin pouring groove, and the main resin pouring groove is communicated with the secondary resin pouring groove. The main resin pouring groove and the secondary resin pouring groove are arranged on the front surface and the back surface of the core plate, and gridding cloth is arranged on the back surface of the core plate, so that resin is more uniformly poured in the core plate, the phenomena of poor resin infiltration, resinwaste and the like are reduced, and the quality and the performance of the core materials is improved.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a blade core material of a wind power generating set and a processing method thereof. Background technique [0002] Blades are one of the important components of wind turbines. As the blades of wind turbines are getting longer and longer, the weight of the blades is also increasing. In order to ensure that the blades are light in weight and high in performance, the core material of the blades is made of blades. One of the key materials. In the molding process of wind turbine blades, vacuum infusion molding technology is usually used. The structure of the core material has a certain influence on the flow properties of the resin during the infusion process, which is ultimately related to the quality of the blade after molding. Therefore, the groove structure of the core material is unreasonable, and problems such as waste of raw materials, uneven penetration speed, and poor in...
