Abstract

The invention provides a method for sealing an airplane skin through expanded polytetrafluoroethylene. The method includes the first step of coating an airplane skin crack with a sealant, the second step of cleaning a face to be pasted of a polytetrafluoroethylene sealing profile, the third step of pasting the polytetrafluoroethylene sealing profile on the airplane skin crack and the fourth step of punching holes in the periphery of the polytetrafluoroethylene sealing profile and connecting the airplane skin and the polytetrafluoroethylene sealing profile through bolts. When the method for sealing the airplane skin through the expanded polytetrafluoroethylene is carried out, the skin crack just needs to be smeared with the sealant, then the polytetrafluoroethylene sealing profile is pasted to the crack, and finally the holes are punched and the bolts are used for fastening the airplane skin and the polytetrafluoroethylene sealing profile. The method for sealing the airplane skin is simple and convenient, the sealing effect is improved under the dual effects of the polytetrafluoroethylene sealing profile and the sealant, and people do not need to wait for curing of the sealant for a long time, so that work efficiency is improved and the maintenance cost is reduced.

Description

technical field [0001] The invention belongs to an aircraft skin sealing method, in particular to a method for sealing an aircraft skin with expanded polytetrafluoroethylene. Background technique [0002] Rainproof sealing is an important part of aircraft design. The current domestic aircraft skin sealing methods all adopt extrusion sealing method. This method has the problems of complicated construction process, long construction period and low work efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a method for sealing aircraft skin with expanded polytetrafluoroethylene, which is used to solve the long construction period and complicated process of sealing the current aircraft skin. The problem of low work efficiency. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a method for sealing aircraft skins with expanded polytetrafluoroethylene, comprising [0005] Step 1...
