Problems solved by technology

[0002] In the manufacturing process of blades, some parts need to be hand-laid up, and there are problems such as large glue content and many air bubbles in the cloth layer during the hand-laid-up process; in addition, it cannot be directly heated after hand-laid up, and the molding cycle is long
However, vacuum infusion molding has a longer molding cycle, and the material cost is relatively high, so it is not suitable to be used in all blades.

Abstract

The invention discloses a hand lay-up process and a device used for the process. The device comprises a vacuum bag film, a resin receiver and a vacuum pump. A flow guide opening is formed in the vacuum bag film, the a resin flow-in opening and an air outlet arranged in a spaced manner are formed in the top of the resin receiver, the resin flow-in opening and the air outlet are communicated with the interior of the resin receiver, the resin flow-in opening is connected with the flow guide opening through a first air exhaust pipe, and the vacuum pump is connected with the air outlet through a second air exhaust pipe. According to the hand lay-up process and the device used for the process, the content of glue of a glass fiber cloth can be reduced, bubbles in the cloth layer can be reduced, the apparent quality of a hand lay-up product is good, and stability is high.

Description

technical field [0001] The invention relates to a hand lay-up process and a device for it. Background technique [0002] In the manufacturing process of blades, some parts need to be hand-laid up, and there are problems such as large glue content and many air bubbles in the cloth layer during the hand-laid-up process; in addition, it cannot be directly heated after hand-laid up, and the molding cycle is long. However, the vacuum infusion molding has a long molding cycle and a relatively high material cost, so it is not suitable to be used in all blades. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art, and provide a hand lay-up process for obtaining high-quality hand-lay-up products and a device for it. [0004] The present invention solves the above technical problems through the following technical solutions: [0005] A device for hand lay-up process, said device comprising: [0...
