Description
Technical field
The present invention relates to the method for repairing and mending field of thermoplastic, and in particular to one kind is using ultrasonic wave-hot in-place repairing
The method of thermoplastic composite defect.
Background technology
Thermoplastic composite has the advantages that many uniquenesses, and such as toughness is high, shock resistance is good, good corrosion resistance, material
Material utilization rate is high, without period of storage limitation, repeats processing etc..In recent years, thermoplastic composite automobile, electronics,
The industries such as electrical equipment, medicine, building materials, ornament materials are widely used, but during long-time use or for special
Structure, thermoplastic composite structure partial region may occur the defects such as layering, crackle, fracture；But because thermoplastic shape is compound
Integral forming process being used material structure, overall structure is replaced and will cause huge loss and waste, therefore urgent need seeks one more
Plant the method for composite sectional repair to greatly improve structure service life, reduce use cost.Composite structure is repaired
Basic object be composite structure is recovered integrality with minimum cost within the shortest time, repairing material therefor should be with
The intensity and rigidity of original structure match, while not increasing the weight of material as far as possible.At present for thermoplastic composite
Repairing can be divided mainly into two kinds of raw material welding and splicing by repairing packing material.
Raw material burning-on method can use magnetic induction method, ultrasonic bonding, under whirling vibration welding and inert gas at present
Welding.Such method is consistent with script material due to repairing point, and all chemical property, thermal property keep constant, so that institute
The binding site of acquisition generally has fabulous mechanical performance, and node quality is high.Another advantage of this method is that thermal source only makes most to connect
The material melting of near-thermal carrier surface, without making malformation to be repaired.
Magnetic-thermoinduction method is to induce high-intensity magnetic field with one or more ferromagnetic coils.The method range of application is wider, but by
In the limitation of sensing heating scope, there is very big difficulty to the sectional repair of Special complex structure；Secondly, the method need to be in repairing
Steel disc is placed between interface, for the placement of thinner thickness or the irregular region of defective locations steel disc difficult to realize；Again, for
Non- fracture defect, with the method there may be due to cannot both sides pressurize so that the problem that cannot be repaired.
Ultrasonic bonding is that mechanical energy is changed into heat energy using the plumb joint of vibration, and the method is applied to being made by impact
Into defect carry out patch type repairing.Portable soldering appliance, mending course simple and fast are had at present.But, the method is current
Docking defect can't be repaired such as crackle, fracture etc..
Whirling vibration method is that mechanical energy is converted into heat energy on interface to be repaired using whirling vibration, and the method can be realized
Breaking type docks the reparation of defect, but cannot realize repairing for the localized crackses of double-ended break without separation.
Bonded process is more conventional thermoplastic composite sectional repair technology, predominantly by splicing, laying, pressurization
The processes such as solidification make the original design requirement of part recovery and profile generally comprise injection, sticking patch and change core repairing etc..
Filling is come unglued mainly for composite edge, is layered and hole equivalent damage or defect, repairs used tool equipment
It is relatively simple, or even can be repaired at room temperature, but it can not be used high intensity, high stress requirement region.Subsidizing rule is
An outside is fixed by being glued in the outside of damaged structure to subsidize piece to recover structural strength, rigidity and design requirement, but
This method can destroy the profile of material, and profile required precision part not high can be used.
Chinese patent CN102922834A discloses a kind of reinforcing chip design of thermoplastic composite perforate product and mends
Strong method, using the radial fiber track layer cyclization matched with osseotomy site shape size to fiber track layer reinforcing chip pair
Perforate product carries out reinforcement.Chinese patent CN102935721A discloses a kind of reinforcing chip of fibrous composite perforate product and sets
Meter and reinforcement.Digging rule is a kind of most wide method for repairing and mending of range of application, but to the requirement of operator and external condition
Also higher, it is necessary first to remove the position of defect or damage, then filled up using mitered method or staircase method, solidification process needs
To overall structure, temperature-pressure is recovered with ensureing product quality with profile in vacuum environment.Sum it up, for bonded process pair
The problems such as composite carries out reparation and still suffers from hardening time long, complex technical process and raw material poor compatibility.Chinese patent
CN103770346A discloses a kind of restorative procedure of cellular thermoplastic plate, and main repairing step includes that position, sawing is filled up,
Plate.
