Problems solved by technology

[0003] However, while the VARTM vacuum infusion process is widely used, its one-time molding process characteristics also have shortcomings, that is, the irreversibility of the process operation, and the product cannot be reworked after forming
The direct consequence of this defect is: the error of human operation may directly cause the scrapping of the entire large component, and the economic loss is very heavy
Once a human error occurs, such as the wrong ratio of the two-component resin matrix, etc., how will it affect the performance of the entire component, how to deal with it, and how to improve it, the process technicians and quality inspection personnel have no basis for query and tracking, and it is very difficult Difficult to analyze

Abstract

The invention relates to a vacuum infusion process capable of producing wind turbine blade samples, which comprises: cleaning the upper half blade mound and the lower half blade mould, applying release agent, and orderly laying a glass fiber layer, bamboo and PVC foam in the lower layer, and a glass fiber layer and a release material layer in the upper layer; laying a sample glass fiber layer on the release material layer; evenly laying release cloth, vacuum membrane and the like on the sample glass fiber layer to form a forming chamber; form a finished upper half blade and a finished lower half blade after vacuum pumping, pressure maintaining, epoxy resin infusion and taking out samples after curing; and heating, curing, cooling and lifting the upper half blade mound and the lower half blade mould. The vacuum infusion process can provide the traceable basis for technicians and quality inspectors; the mechanical properties of the blade can be analyzed under the premise of not damagingfinished blades, and the tests for the properties of the blade samples are only needed; and the difficulty of material selection and testing is lowered, but the strength properties of the blades are not influenced; and the test results can present the true properties of the blades.

Description

technical field [0001] The invention relates to a vacuum infusion process for wind power generator blades, in particular to a vacuum infusion process for wind power generator blades capable of producing prototypes. Background technique [0002] At present, the vast majority of large-scale composite components in the world use the VARTM vacuum infusion and infusion process. Due to the vacuum sealing operation, the VARTM process can reduce the damage to personnel and the pollution to the working environment caused by the volatile matter in the resin matrix, and eliminate product The air bubbles in the product can improve the mechanical properties of the product by more than 20%. It can be uniformly pressurized to make the performance of the product uniform. cost. [0003] However, while the VARTM vacuum infusion process is widely used, its one-time molding process characteristics also have shortcomings, that is, the irreversibility of the process operation, and the product ca...
