Problems solved by technology

At this time, traditional epoxy glass fiber reinforced composite materials cannot meet the increased lateral load-bearing requirements
And the existing unidirectional fiberboard, after long-term use, will appear cracks, transverse cracking and other phenomena, resulting in potential safety hazards in the wind blade girder made of fiberboard

Abstract

The invention discloses a fiber reinforced plate strengthening process for wind blade girder manufacturing. Transverse fiber bundles are uniformly enwound at a fiber plate. The fiber plate comprises longitudinal fiber bundles pulled in the horizontal technology direction and resin attached to the surfaces of the longitudinal fiber bundles. Transverse fiber bundles are arranged at the longitudinalfiber bundles. The longitudinal fiber bundles provided with the transverse fiber bundles penetrate through a pultrusion solidification mold to form the fiber plate. The fiber reinforced plate strengthening process for wind blade girder manufacturing aims to overcome defects in the prior art. The fiber reinforced plate strengthening process for wind blade girder manufacturing having no fracturing and being high in strength and in fiber plate transverse load bearing force is provided. The transverse fiber bundle technology is added on the basis of existing longitudinal fiber bundles, and the problems of an existing fiber plate that fracturing is liable to occur after application and the fiber plate is low in transverse load bearing force are solved.

Description

technical field [0001] The invention relates to the field of fiberboard manufacturing, in particular to a fiber-reinforced board reinforcement process for manufacturing wind blade girders. Background technique [0002] The blades of wind turbines are the key components for wind power equipment to convert wind energy into mechanical energy, and their manufacturing costs account for about 15%-30% of the total cost of wind turbines. The blades of large wind turbines are basically made of composite materials, and the design and manufacture of blades is the key technology of wind turbines. [0003] In the design of general blades, the girder is the focus of blade design. The girder is the main component that provides the stiffness of the blade. A high-quality girder should have the characteristics of light weight and high directional modulus. The current mainstream of girder materials are composite materials, mainly epoxy glass fiber reinforced composite materials. Epoxy glas...
