Description

Outfield microwave rapid repairing device and using method

Technical Field

The invention relates to a design of an outfield microwave quick repairing device and a connecting mechanism thereof, in particular to a design of a microwave repairing device and a connecting and fixing mechanism for a damaged component made of a fiber reinforced resin matrix composite material, and specifically relates to a design and a use method of equipment for the outfield microwave repairing device and a self-locking connecting rod mechanism made of the fiber reinforced resin matrix composite material.

Background

The use amount of the advanced fiber reinforced thermosetting composite material with excellent mechanical properties in the aircraft at present becomes a key technical index for measuring the advancement of the aircraft. Especially in the military and civil aviation field, the great application of the fiber reinforced composite material can obviously reduce the structural weight of the aircraft, improve the physical performance of the aircraft, greatly reduce the number of parts, simplify the assembly process and shorten the manufacturing period. However, in a battlefield environment, the fiber reinforced composite material is easily damaged by bird impact, lightning strike or bullet, and the time of war is fleeting, so that the rapid repair of the damaged part of a warplane is highly required. And the damage repairing task of the composite material component of the airplane is difficult to realize quickly and efficiently in an external environment, the repairing labor amount is huge, and the requirement on the physical quality of workers is extremely high.

At present, when repairing a damaged composite member of an aircraft in an external field environment, a traditional repairing method is a hot repairing method, namely an indirect heating repairing method of laying an electric blanket and the like on a region to be repaired is adopted. And heating and curing the patch of the area to be repaired in a heat conduction mode in the area to be repaired. There is also a method of directly heat-curing a carbon fiber composite material by directly energizing the carbon fiber composite material, for example, patent CN108407340A, which discloses a repair technique of heat-curing a carbon fiber reinforced resin-based composite material member by using an electrical loss. However, the method has the disadvantages of large preparation workload before repair, complex repair process, long repair period, high energy consumption and poor economic benefit, and the quality after repair is difficult to ensure and has high technical requirements on workers.

In recent years, external field rapid repair equipment using microwave curing technology has also appeared. For example, patent nos. CN103802339A and CN105584061A both disclose a repair method for microwave curing of carbon fiber reinforced composite materials by generating microwave energy using a microwave source. However, the repair process method for the carbon fiber composite material is only suitable for repair operation on a simple plane, and cannot solve the repair task of the damaged part of the fiber reinforced composite material member with a variable curved surface. Moreover, the technique of the invention requires the workers to work in the repair area for a long time, and the physical strength of the workers is greatly consumed. For example, if the region to be repaired is located at the lower end of the wing, a worker needs to press the fixed resonant cavity and the component to be repaired to be tightly attached to each other for a long time. This not only brings serious microwave leakage risk and causes damage to the body of the worker, but also greatly consumes the physical strength of the worker, so that these resonator devices suitable for simple planes are difficult to be popularized on a large scale. Up to now, no device for repairing the damage of the fiber reinforced composite material member can realize the repairing operation of any complex curved surface and solve the problem of extremely high labor intensity of workers in the repairing operation.
