Description
Technical field
The invention belongs to Metal Structure Damages to repair field, and specifically a kind of corrosion of metal structure damaged composite material is viscous
Connect repair method.
Background technique
Metal structure by surrounding medium chemical action or electrochemical action and corrode, the generation of corrosion not only can
Direct economic damage is brought, and ecological environment can be destroyed.After metal structure is corroded, corrosion product and ontology are detached from
It will lead to structural section thickness to become smaller, structural-load-carrying capacity decline.If handled not in time, corrosion can further develop, finally
Lead to structural failure.Although having put into the corrosion protection of metal structure very much, it is difficult to avoid corruption completely
The generation of erosion.It after corrosion occurs, places under repair in time to structure, restores structural-load-carrying capacity, and corresponding anticorrosion is taken to arrange
It applies most important for the service life of extending structure.
After corroding at present for metal structure, if corrosion damage size is more than damage tolerance, machine is generallyd use
The mode that tool is repaired reinforces structure, and carries out corrosion protection.If mainly taking corruption without departing from damage tolerance
Lose safeguard procedures.Metal reinforcing plates are connected to corrosion damage knot by repair of machine, the form mainly taking riveting or being spirally connected
Structure, to restore the bearing capacity of structure.Rivet, be spirally connected repairing need drill on original structure, be bound to cause structure in this way
Secondary damage, and repair construction and need certain space.It just needs detaching structure in order to obtain construction space or opens fabrication hole,
The time for repairing construction in this way will extend.Although after repairing, safeguard procedures can be taken to prevent the generation of corrosion, one
In a little rather harsh environments, for example, high temperature and humidity marine environment with high salt or the direct structure used in the seawater, corrosion
Usually also occur that.At this point, main measure is exactly to reinforce checking and constantly be protected.It is undoubtedly will increase in this way using dimension
The cost of shield.Therefore, the repair method that can restore structural strength and excellent Corrosion Protection well is taken, it is right
It is very significant in corrosion of metal structure damage repair.
It is that composite material laminated board sticking patch is adhered in damaged metal structure that composite material bonding, which is repaired, plays recovery knot
The effect of structure intensity.It is secondary with avoiding relative to traditional mechanical connection repairing that composite material bonding repairs damaged metal structure
It damages, slow down stress concentration, improve corrosion-resistant and fatigue performance, weight increases few, outstanding advantages of designability is strong.More
It is important that composite material itself has very excellent corrosion resistance, moreover, composite panels are adhered to metal structure
After upper, damaged structure and external environs also can be avoided corroding again by bonding region.This patent is just to provide one
The composite material of kind metal erosion damaged structure is bonded repair method.
