Description
Technical field
The present invention relates to a kind of production method of composite material for repairing, which repairs for composite product
It mends, and solidifies under middle cryogenic conditions.
Background technique
Composite material is successfully applied to Aeronautics and Astronautics because it is with the excellent characteristics such as high specific strength, specific modulus, corrosion-resistant
Fields are waited with civilian with military and industry.However, composite material because bearing load and damp and hot factor repeatedly under service condition
Effect, be inevitably generated local damage and micro-crack.If these damage locations cannot be repaired timely, not only very
The normal use performance of structural member is influenced in big degree and shortens its service life, and may thus be caused macrocrack and be drawn
Hair fracture, causes a serious accident.Since composite material involves great expense, technical value added is high, it is replaced, reproduction undoubtedly
It will cause the huge waste of resource；In contrast, the cost repaired to it is much lower.Currently, in military secret and civil aircraft
On most of the composite element that uses all using vacuum bag-autoclave method molding, molding needs the condition in high temperature and pressure
Lower progress makes entire if part needs carry out repairing solidification in autoclave using the bulk material of part when part is repaired
The high temperature and high pressure that part all undergoes repairing area the same increases the thermal history of part, improves part and generates other defects
Probability, reduce the service life of part, and numerous parts can not be disassembled from aircraft and be repaired, and cannot be made
With solidification of hot-press tank repairing area.When being repaired using part noumenon material, if not solidified in autoclave, temperature
It is unable to satisfy material requirements with pressure, it is lossless unqualified to eventually lead to repairing area.
Summary of the invention
Bring reduces part service life, repairs the unqualified and energy when using part noumenon materials repairing to overcome
The problems such as big is consumed, the present invention provides a kind of methods of the composite repair material of middle low-temperature setting.
In order to solve the above technical problems, a kind of production method of the composite material for repairing of the present invention, including walk as follows
It is rapid:
S1 determines the area of the patching material of production according to repairing area；
Requirement of the S2 according to the gel content of production patching material, glue weight needed for calculating the patching material of production corresponding area
Amount, configures corresponding weight glue；
S3 chooses non-porous isolation cloth as backing, and each side of surrounding is all larger than patching material about 100mm；
The half of configured glue is uniformly coated on non-porous isolation cloth by S4；
The patching material of required production is laid on the non-porous isolation cloth of gluing by S5；
Remaining glue is uniformly coated on patching material by S6；
S7 the patching material of gluing is completely covered with there is hole isolation cloth;
S8 is by the non-porous isolation cloth made, patching material and has hole isolation cloth to be placed into plate tooling as a whole, encapsulation
Vacuum bag vacuumizes 2 to 3 minutes；
S9 takes out non-porous isolation cloth, patching material and has hole isolation cloth, according to the shape of repairing area, cuts patching material.
The patching material is carbon fiber or glass fabric.
The glue is middle-low-temperature resin or middle low-temperature setting glue.
The vacuum pressure vacuumized is 0.085-0.075MPa.
The present invention provides a kind of production method of composite material for repairing, the patching material made using this method
When repairing for composite product, does not need for entire part to be placed in autoclave and repair, it is only necessary to using heat lamp, vulcanize
Repairing can be completed to patch area local heating in the equipment such as instrument, and low energy consumption, easy to operate；Use medium temperature glue and carbon fiber or glass
Patching material made of glass fabric can carry out repairing solidification under middle low temperature, avoid repairing part experience high temperature, can protect
Demonstrate,prove repairing quality.
Detailed description of the invention
Fig. 1 is the schematic diagram of the repairing composite material of low-temperature setting in production of the invention.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
A kind of production method of the composite material for repairing of the present invention, includes the following steps:
S1 determines the area of the patching material of production according to repairing area；
Requirement of the S2 according to the gel content of production patching material, glue weight needed for calculating the patching material of production corresponding area
Amount, configures corresponding weight glue；
S3 chooses non-porous isolation cloth 7 and is used as backing, and each side of surrounding is all larger than the about 100mm of patching material 6；
The half of configured glue is uniformly coated on non-porous isolation cloth 7 by S4；
The patching material of required production is laid on the non-porous isolation cloth 7 of gluing by S5；
Remaining glue is uniformly coated on patching material by S6；
S7 the patching material of gluing is completely covered with there is hole isolation cloth 5;
S8 is by the non-porous isolation cloth 7 made, patching material 6 and has hole isolation cloth 5 to be placed on plate 1 as a whole, encapsulation
Vacuum bag 4 vacuumizes 2 ~ 3 minutes in the case where vacuum pressure is 0.085-0.075MPa；
S9 takes out non-porous isolation cloth 7, patching material 6 and has hole isolation cloth 5, according to the shape of repairing area, cuts repairing material
Material.When lay-up repair material, removes upper and lower non-porous isolation cloth and have hole isolation cloth.
The patching material is carbon fiber or glass fabric.
The glue is middle-low-temperature resin or middle low-temperature setting glue.
It is first according to the area of the patching material 6 of required production and the gel content for the patching material made come really with glue
The weight of glue needed for fixed needs to weigh the group of corresponding weight by glue ratio requirement when glue is bi-component or multicomponent glue
Point, then each component is stirred evenly；Followed by brush coating, one layer of glue is brushed first on the non-porous isolation cloth 7 as backing, then
Patching material 6 is laid on non-porous isolation cloth 7, then by glue it is linear be poured over patching material 6 everywhere, will with scraper plate
Glue uniformly scrapes off；Followed by vacuumizing, covering one layer on patching material has hole isolation cloth 5, then in non-porous isolation
The surrounding of cloth 7 puts a circle ventilative viscous 3, and ventilative glue does not contact patching material 6, reuses putty item 2 and vacuum bag 4 on plate 1
Encapsulated vacuum bag vacuumizes 2 ~ 3 minutes in the case where vacuum pressure is 0.085-0.075MPa.
