Monitoring and repairing method for curing and cementing of composite material

Abstract

The invention provides a method for monitoring and repairing composite material curing adhesive bonding, which belongs to the field of composite material adhesive bonding repair equipment. The method is based on a composite material curing adhesive repair instrument, which includes a body, and a curing source module is provided at the adhesive repair working surface of the body, and the curing source module provides energy for the composite material prepreg to cure, and the curing The source module is surrounded by multiple temperature zones from the inside to the outside. Each temperature zone is equipped with an independent curing source for providing energy to the temperature zone. The multiple temperature zones are used alone or in conjunction with each other, and according to The shape of the damaged area of ​​the structure is determined, and the temperatures of multiple temperature zones are the same or different. The present invention is based on multi-area curing source control, establishes a uniform and stable temperature field under external field conditions, and solves the problem of avoiding excessive temperature differences. Based on the principle of heat conduction, the multi-area temperature field control technology is used to achieve uniform and stable bonding repair areas. temperature field while avoiding excessive temperature differences.

Description

technical field [0001] The invention relates to the field of composite material bonding repair equipment, in particular to a method for monitoring and repairing composite material curing bonding. Background technique [0002] In recent years, composite materials have been more and more widely used in aircraft and other equipment. Therefore, if the daily maintenance and repair of aircraft and other equipment containing composite materials cannot be effectively resolved, it will definitely affect the normal operation of aircraft and other equipment. use. [0003] Under field conditions, especially in wartime, repairs are basically in-situ repairs. For composite material bonding and repair, heat curing is mainly used, and a small part of light curing is also used. [0004] Thermal curing requires a stable and uniform temperature field to ensure the strength of the composite patch and the bonded repair structure, and to better repair the bearing capacity of the damaged structu...

AI Technical Summary

Problems solved by technology

However, at present, light curing is usually used to prepare composite patches in advance, which cannot achieve in-situ repair under external field conditions.
