The invention provides a seal performance testing method for a sealant. The seal performance testing method comprises the following steps: constructing a test chamber by using organic glass, an aluminum alloy skin and a dacron silk ribbon; sealing the test chamber by using the sealant; putting the sealed test chamber in a normal temperature environment, enabling the interior of the test chamber tobe filled with gas with first preset pressure, and observing a pressure gage connected onto the test chamber; if the numerical value of the pressure gage is not reduced, putting the test chamber in an environment of 80 DEG C or -55 DEG C, enabling the interior of the test chamber to be filled with gas with second preset pressure, and observing the pressure gage; and if the numerical value of thepressure gage is not reduced, the seal performance of the sealant is good.
Description
technical field [0001] This application relates to the technical field of aircraft, and specifically provides a method for testing the sealing performance of a sealant. Background technique [0002] Due to the airtight requirements of the aircraft for the sealing structure of the overall canopy, it is necessary to apply a new type of plexiglass and sealant to the overall canopy structure. The thickness of the new plexiglass is quite different from that of the previous models, and the new sealant is also used in this compartment for the first time. The conventional test methods in the past did not comprehensively include the performance tests of the plexiglass and sealant at room temperature, high temperature and low temperature. , unable to meet the performance verification of new materials. Contents of the invention [0003] In order to solve at least one of the above-mentioned technical problems, the application provides a method for testing the sealing performance of a...
