Problems solved by technology

[0003] Because the pultruded board is a formed hard board, when the resin is poured, the resin can only bypass the pultruded board to infiltrate the glass fiber cloth between the pultruded boards, which is very likely to cause a lack of glue in some gaps and uneven infiltration. Affects final shaped blade strength
In addition, it is difficult to control the amount of impregnation by using resin infiltration, which further reduces the strength of the blade, and the above-mentioned manufacturing process is relatively cumbersome, and the process takes a long time

Embodiment Construction

[0020] In order to enable those skilled in the art to better understand the present invention, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] refer to figure 1 and figure 2 , figure 1 is a schematic diagram of a girder layup according to an embodiment of the present invention, figure 2 is a flowchart of a blade part manufacturing process according to an embodiment of the present invention. An embodiment according to the present invention provides a manufacturing process of a blade component. The blade component may be a main beam of the blade, or a component at another position. In the following description, the main beam will be used as an example for illustration.

[0022] When the main girder is manufactured, it can be carried out on a separate special mold, and then the formed main girder is laid on the blade shell to complete the manufacture of the blade shell. Alternatively, wh...

Abstract

The invention discloses a manufacturing process of blade parts. The manufacturing process of blade parts comprises the following steps of laying multiple layers of pultrusion plates on a die in sequence, and laying prepreg and / or adhesive film between every two adjacent layers of pultrusion plates; vacuuming the laying area of the multiple layers of pultrusion plates, and compacting the pultrusionplates and the prepreg and / or adhesive film; and solidifying the prepreg and / or adhesive film in the vacuum environment. According to the manufacturing process of blade parts, because the pultrusionplates are glued with the prepreg and / or adhesive film, the resin infusion process is avoided, and the weight and the strength of a main beam or the blade parts can be accurately controlled.

Description

technical field [0001] The invention belongs to the field of blade manufacturing, in particular, the invention relates to a process for manufacturing blade parts. Background technique [0002] At present, the main beam forming process of the blade is mainly the traditional vacuum infusion method. The resin is poured after the parts are laid. The basic process route generally includes the following steps: cleaning the main beam manufacturing mold, using mold cleaner, sealing agent and release agent Wait for the mold to be cleaned; to lay the materials, first lay a layer of diversion net on the main beam manufacturing mold, then lay a layer of isolation film, then lay the first layer of pultruded board on the mold, and then pull Lay one or more layers of glass fiber dry cloth on the top of the extruded board, and then continue laying a layer of pultruded board. During this period, according to the strength and weight of the main beam, the Place the core material between them,...
