Abstract

The invention discloses a composite material component rapid repairation device and a composite material component rapid repairation method based on microwaves, and relates to the technical field of composite material component external field rapid repairation technology and equipment. According to the invention, one end of a microwave generating source is connected with a microwave transmission line, and the other end of the microwave transmission line is connected with one end of a coaxial waveguide converter and one end of a bi-directional coupler; the other end of the coaxial waveguide converter and the other end of the bi-directional coupler are connected with one end of a microwave radiator; the other end of the microwave radiator is oppositely provided with a composite material component; one side of the composite material component, which is close to the composite material component, forms a to-be-repaired region; the to-be-repaired region is connected with one end of a signal amplifier by an optical fiber sensor, the other end of the signal amplifier is connected with the signal converter, the other end of the signal converter is connected with one end of a control unit, and the other end of the control unit is connected with the other end of the microwave generating source. According to the invention, the aims of high curing speed, uniform heating, excellent repairation component quality and health monitoring of the repairation region are reached.

Description

[0001] technical field [0002] The invention relates to the technical field of field rapid repair technology and equipment of composite material components. [0003] Background technique [0004] The application of advanced composite materials in aircraft structures is gradually expanding. The use of composite components in civil aircraft has gradually expanded from secondary load-bearing components, such as flaps, ailerons, and empennages, to main load-bearing components such as wing spars and bulkheads. Due to the continuous expansion of the application range of composite materials, it is extremely important to improve the repair level of composite materials and the repair technology of damaged parts. Composite material repair technology is a new type of aircraft structure repair technology. At present, electric heating blankets are mainly used to repair damaged areas of composite materials. Due to the traditional repairing method, there are common problems such as sl...
