Abstract

The embodiment of the invention provides a resin composite material, a preparation method, a blade shell and a wind generating set, the resin composite material comprises polydicyclopentadiene resin and a catalyst, and the weight ratio of the catalyst to the polydicyclopentadiene resin is 0.001%-0.5%. When the resin composition provided by the embodiment of the invention is used for preparing the blade of the wind generating set, the polydicyclopentadiene resin system is low in viscosity at room temperature, so that the filling speed is very high, and the preparation time of the blade of the wind generating set can be effectively shortened. The weight of the blade can be reduced; and the polydicyclopentadiene resin does not need to be post-cured, the curing time is short, and the preparation efficiency of the blade can be further improved. In addition, the cost of the polydicyclopentadiene resin is lower than that of epoxy resin and polyurethane resin systems. Therefore, the resin composite material provided by the embodiment of the invention not only can effectively improve the preparation efficiency of the blade of the wind generating set, but also can effectively reduce the manufacturing cost of the blade.

Description

technical field [0001] The present application relates to the technical field of wind power, and in particular to a resin composite material, a preparation method, a blade shell and a wind power generating set. Background technique [0002] With the continuous development of wind power generation technology, people put forward higher requirements on the performance and cost of wind power generators. Blades are an important part of wind turbines, and their performance and cost directly affect the performance and manufacturing costs of wind turbines. [0003] At present, the shell of wind turbine blades is mainly made of two-component epoxy resin system infused with glass fiber fabric and solidified by vacuum pressure. Epoxy resin is a polymer with two or more epoxy groups on its molecule. The epoxy resin system for blade infusion is composed of main epoxy resin and amine curing agent. Due to the high viscosity of the epoxy resin at room temperature, the pouring time of the...
