Example Embodiment

[0028] The principles and features of the present invention will be described below with reference to the accompanying drawings. The examples cited are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0029] Such as figure 1 As shown, a method for repairing a large composite shelter includes the following steps:

[0030] Step 1: Cut and polish the damaged skin of the large composite square bulkhead;

[0031] Step two, dig out the core material at the damaged part of the damaged skin to form a core material repair cavity;

[0032] Step 3: Unload the repaired core material in the core repair cavity, and encapsulate the repaired core material;

[0033] Step 4: Lay the repair skin on the surface of the repair core material, so that the repair skin is filled with the cut and polished damaged skin;

[0034] Step 5: Lay a release cloth on the surface of the repaired skin, and paste the prefabricated vacuum bag on the surface of the rel...

Abstract

The invention relates to a repairing method of a large composite material shelter. The method comprises the following steps: cutting and polishing the damaged sheath of the wall of the large composite material shelter; digging out the damaged core material at the rear portion of the damaged sheath to form a core material repairing cavity; carrying out repairing core material discharging in the core material repairing cavity, and carrying out edge covering and loading of the repairing core material; laying a repairing sheath on the surface of the repairing core material; laying a demolding cloth on the surface of the repairing sheath, and allowing a whole repairing position to be in sealed environment; injecting a resin system to the repairing sheath through the demolding cloth by using a flow guiding system and a glue injecting system; and removing the demolding cloth on the surface of the repairing sheath, and polishing the demolding cloth removed surface of the repairing sheath. The shelter repairing method provided by the invention has the advantages of few consumables, low cost, good effect, elimination of the innate discontinuity characteristic of fibers in laminates, caused by traditional imbed parts, and solving of the repairing problem of large composite material shelters through well combining fault fibers.

Description

technical field [0001] The invention relates to a repair method for a shelter, in particular to a repair method for a large composite material shelter. Background technique [0002] At present, there are many domestic studies on the field of composite material shelters, but less research on the repair of shelters. With the rapid development of the composite material industry and the continuous improvement of technical requirements for lightweight and intelligent shelters, for There will be more and more problems in the follow-up repair of composite shelters, so the repair technology of large composite shelters is imminent. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a repair method for a large composite shelter with simple operation, low repair cost and high success rate. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a method for repai...
