Problems solved by technology
This harsh marine environment with high salt spray, high humidity and heat will cause serious corrosion damage to aircraft structures, especially structures that withstand high loads and high stress levels, seriously affecting aircraft safety and reliability.
As a new type of structural form, advanced reinforced structures can significantly inhibit crack propagation, enhance structural fatigue and damage tolerance performance, and at the same time, there are hidden dangers of corrosion damage, because advanced reinforced structures are connected by metal and composite materials, the two exist Potential difference, if the coating is not properly protected, it is easy to form corrosion, causing the adhesive layer of the advanced reinforced structure to fail, thereby affecting the performance; therefore, it is important to carry out research on the protection design and verification of the coating of the advanced reinforced structure for the engineering promotion of the advanced reinforced structure significance

The embodiment of the invention discloses a coating protection treatment method of an advanced reinforced structure. The method comprises the following steps: preliminarily determining a protection system of a to-be-selected coating of an advanced reinforced structure according to environmental analysis on an application part of the advanced reinforced structure; after test verification of the preliminarily determined protection system of the to-be-selected coating, selecting a protection system of the advanced reinforced structure meeting the environment of the application part; and carryingout environment comprehensive evaluation and analysis on the selected protection system, and verifying the effectiveness and durability of the protection system. According to the scheme provided by the embodiment of the invention, the corrosion protection performance of the advanced reinforced structure in a corrosion environment can be improved, the engineering application of the advanced reinforced structure in an airplane is accelerated, and the purposes of prolonging the airplane maintenance interval and service life and improving the airplane safety and economy are achieved.
Description
technical field [0001] This application relates to but is not limited to the technical field of aircraft design, especially a coating protection treatment method for advanced reinforced structures. Background technique [0002] Advanced reinforced structure is a new type of structure. The fiber strips with reinforced functions are glued and connected to the structure of the high-stress area of the aircraft metal to increase the transmission path in the local area, reduce the stress level in the local area, and improve the fatigue and damage tolerance performance of the area. [0003] With the continuous advancement of my country's deep-sea strategy, the environmental adaptability of aviation equipment is more important. Aircraft have been in service and used in coastal areas for a long time. Keep it in a moist state for a long time, and it is easy to accumulate condensed water during take-off and landing, and it is easy to form dry and wet alternate marine corrosion condit...
