Abstract

The invention provides a vacuum infusion forming process. The process comprises the steps that a glass fiber reinforced material layer, a demolishing cloth and a flow guiding seal assembly are laid on a mold in sequence, the flow guiding seal assembly comprises a flow guiding net, a flow guiding pipe and a vacuum covering film, and the value range of the thickness of the vacuum covering film is 0.5 mm-30 mm; the flow guiding pipe is connected with a vacuumizing device and a glue injection pipeline, and the mold is sealed through the vacuum covering film; and vacuum infusion is conducted. According to the process, the vacuum covering film with the large thickness is used for replacing a vacuum bag film with a small thickness in the prior art, so that the problems that the vacuum bag film is liable to be sticked, a leak is difficult to find and the vacuum bag film can not be reused are solved. A large amount of materials and labor are saved, and accordingly the work efficiency of the vacuum infusion forming process is improved.

Description

technical field [0001] The invention relates to the technical field of composite material vacuum infusion molding, in particular to a vacuum infusion molding process. Background technique [0002] With the utilization value of wind energy gradually emerging and the rapid development of wind power generation technology, people need to manufacture and install a large number of wind power generators to obtain more wind energy. Wind turbines obtain wind energy through blades. Therefore, the manufacturing quality of blades directly affects the performance of wind turbines. The blades are usually thin-shell structures made of composite materials, and their forming involves a vacuum infusion molding process. [0003] The existing blade production process is to lay glass fiber reinforced material on the blade production mold first, and then use the vacuum infusion molding process to manufacture the blade. The steps of the vacuum infusion molding process are: laying auxiliary mater...
