Abstract

The invention relates to the technical field of aviation equipment body structure microwave curing repair, in particular to a self-adaptive portable microwave heating repair bag, a manufacturing process and a using method, the repair bag comprises a to-be-repaired piece, and further comprises a vacuum bag film connected to the to-be-repaired piece through a sealing rubber strip; demolding cloth and an isolating membrane; the self-adaptive portable wave absorbing bag is arranged above the vacuum bag film; a portable microwave radiator cavity; and packaging the assembly. According to the invention, the self-adaptive portable microwave heating repair bag is manufactured by selecting the wave absorbing liquid, selecting the material of the wave absorbing bag and analyzing and selecting the packaging process, so that the curing speed is accelerated, the matrix is uniformly heated, the repair strength is improved, the self-adaptive portable microwave heating repair bag is not influenced by the attribute of the repair material, and the service life of the repair bag is prolonged. The application range of the microwave curing technology is expanded while the strength of the repair area is further improved; in addition, the mode of absorbing waves through liquid and transmitting waves through the outer bag is adopted, and on the premise that rapid heating is achieved, it is effectively guaranteed that the temperature in the bag is uniform.

Description

technical field [0001] The invention relates to the technical field of microwave curing and repairing of air equipment body structures, in particular to an adaptive portable microwave heating repair bag, a manufacturing process and a using method. Background technique [0002] Adhesive repair technology is a commonly used damage repair technology for aircraft structures. In adhesive repair, the curing process of the adhesive has a great influence on the repair quality. The traditional heat conduction heating and curing technology generally has problems such as slow heat transfer speed, large temperature gradient, uneven curing and low curing rate, and the problem of "heat affected zone" is difficult to solve, which seriously affects the quality of aircraft bonding repair. [0003] Microwave curing can better overcome the shortcomings of traditional curing technology, and can greatly shorten the maintenance time and reduce the repair cost, and has a good application and deve...
