Title:
COMPOSITE MATERIAL FAN BLADE AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/252762
Kind Code:
A1
Abstract:
The present application relates to the field of wind power blades, and specifically discloses a composite material fan blade and a preparation method therefor and an application thereof. The composite material fan blade comprises a housing, a main beam, a web plate, a trailing edge beam, and a blade root preform, and further comprises the following components by a mass mixing ratio: 30-40% of a HYVER resin, 45-55% of a fiber raw material, 0-20% of a core material, and 0-10% of an epoxy structural adhesive. The present application uses the HYVER resin as a structural layer, and the prepared composite material has excellent mechanical properties, so that on the premise of satisfying the design requirements of the blade, the number of laying layers can be reduced, and then the purpose of weight reduction is achieved; because the present application uses the HYVER resin as the structural layer, the cost of the HYVER resin can be obviously lower than that of existing mainstream materials, and the mechanical properties of the HYVER resin are higher than those of the existing mainstream materials, thereby facilitating the reduction of the cost and the improvement of the strength of the fan blade; and the filling efficiency of the HYVER resin is high, and thus the whole fan blade has good applicability.
