Abstract
The invention discloses a thermoplastic composite material joint connecting method. The method comprises the following steps: thermoplastic composite material joint parts are pretreated; thermoplastic composite materials are fixed on a fixture in a joint part opposing or lap joint manner; carbon fiber one-way belts or fabrics are clamped between the thermoplastic composite material joint parts; one parts of the carbon fiber one-way belts or fabrics are left out of the joint parts, are coated with electric conducting glue, and are clamped on electric conducting clamps of heating equipment; a direct-current power supply of the heating equipment is connected until the joint parts are welded to form a joint; the shape of the joint is finished; and the like. The method has the following effects: the prepared joint structure is lower in influence on in-surface performances of the thermoplastic composite materials, reduces the environmental sensitivity, is lower in weight increment, is lower in shape change, can improve a combining effect between the thermoplastic composite material joints, can improve the mechanical performance and the reliability of the thermoplastic composite material joint structures, and reduces the practical risk of the thermoplastic compound material joint structures.
Description
Technical field
The invention belongs to thermoplastic composite recovery technique field, be specifically related to a kind of thermoplastic composite connector connecting method.
Background technology
Development along with composite, due to thermoplastic composite there is specific strength and specific stiffness are high, designability is strong, good anti-fatigue performance, corrosion resistance is good and is easy to the advantages such as global formation, therefore the civil areas such as the military fields such as aerospaceplane, guided missile, rocket and artificial satellite, and racing car, boats and ships, bullet train, bridge and wind-power blade it are widely used to.But because of its manufacturing process and handling characteristics thereof, thermoplastic composite is manufacturing and is inevitably relating to joint connectivity problem in repair procedures.Generally adopt machinery or adhering method at present, although mechanical means is easier, processing performance is more stable, not by the impact of construction environment, but serious stress can be produced at nail place when shortcoming is screw connection to concentrate, so that original structure produces damage, and have securing member etching problem, thus connecting portion mechanical property is more weak, cause that service life is relatively short, but also damage repair can be caused bigger difficulty, such as there will be jointing deformation, again the punching problem such as insufficient strength, so meeting emergency usually used as interim method of attachment.Adhering method mainly includes subsidizing and dock two kinds of methods, although it is longer to glued joint the structural life-time connected, generally can forever use, but, this connected mode equipment needed thereby complex process, and need to lean on the load between glue-line transmission sticking patch and connected composite structure, therefore reliability is low, environmentally sensitive, and glue-line damage not easily detects.
Therefore, it is badly in need of a kind of thermoplastic composite connector connecting method reliably of invention so that it is technique is simple and convenient, and joint connection effect can be improved, thus recovering to a greater degree or improving composite joint structural mechanical property.
Summary of the invention
In order to solve the problems referred to above, it is an object of the invention to provide a kind of thermoplastic composite connector connecting method.
In order to achieve the above object, thermoplastic composite connector connecting method provided by the invention includes the following step of carrying out in order:
1) joint area of two thermoplastic composites to be connected is carried out pretreatment；
2) above-mentioned thermoplastic composite relatively or is fixed on fixture in the way of overlap joint by joint area；
3) carbon fiber one-way band or fabric are clipped in the middle of above-mentioned two thermoplastic composite joint area, and outside joint area, reserve part carbon fiber one-way band or fabric, coat conducting resinl at the position that reserves of carbon fiber one-way band or fabric and be clamped on the conductive clamp of firing equipment afterwards, being then turn on the DC source of firing equipment；
4) by firing equipment, carbon fiber one-way band or fabric are passed into DC current, the resistance of carbon fiber one-way band or fabric self is utilized to produce Joule heat, joint area melted by heat is made, until the joint area of two thermoplastic composites is welded together and forms joint at the temperature of 180 260 DEG C；
5) terminate energising, make thermoplastic composite cool down in atmosphere, then remove fixture, and butt joint profile is repaired.
In step 1) in, it is polish in first butt joint position that the described joint area to two thermoplastic composites to be connected carries out the method for pretreatment, then uses washes of absolute alcohol totally and to dry.
In step 3) in, the conduction time of described firing equipment is 8 10 minutes.
In step 3) in, described carbon fiber one-way band or the surface of fabric are with thermoplasticity sizing agent.
Thermoplastic composite connector connecting method provided by the invention has the advantages that made joint design is less to performance impact in thermoplastic composite face, environmentally sensitive property reduces, structure weightening finish is less, profile variation is less, and the combination between thermoplastic composite joint can be improved, it is thus possible to improve mechanical property and the reliability of thermoplastic composite joint design, reduce the practical risk of thermoplastic composite joint design.
