Description
Technical field
The invention belongs to communication antenna radiator material selection field, in particular to one of field carbon fiber covers copper
Net composite material and its application as antenna radiator.
Background technique
Carbon fibre material is the composite material being combined by carbon fiber and epoxy resin, due to the high (tensile strength of intensity
Up to 900MPa), small (density is only 1.5g/cm to specific gravity3), the characteristics such as corrosion-resistant, fatigue performance is good, in aviation, boat
It, bullet train, engineering construction field are used widely, be a kind of current high tech composite materials.
Carbon fibre material is a kind of semiconductor material, has certain electric conductivity, resistivity is generally 1.0 × 10-4Ω m~
1.0×10- 6Between Ω m, much higher than metal materials such as copper, aluminium, (copper is 1.72 × 10-8Ω m, aluminium 2.85 × 10-8Ω m), at present
It is used in every field mainly as structure stress part, is not suitable as antenna radiator and is used in communication field, especially
It is the antenna radiator for thering is certain transmission power to require, which greatly limits carbon fibre materials to lead as antenna radiator in communication
Application in domain, the especially application in vehicle-mounted, boat-carrying, airborne etc. to weight, the more demanding occasion of mechanical strength.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of carbon fiber of good conductivity cover copper mesh composite material and
Its application as antenna radiator.
The present invention adopts the following technical scheme:
A kind of carbon fiber covers copper mesh composite material, including two sections or more of carbon fiber round tube, thes improvement is that: in carbon fiber
The surface of round tube is embedded in copper mesh, is linked together between each section of carbon fiber round tube by metal joint, metal joint and carbon fiber
It is fitted together by way of riveting or being spirally connected between round tube, is then welded on one by silver soldering between metal joint and copper mesh
It rises, then the covering winding epoxy laminate glass fabric except copper mesh and metal joint, finally again in epoxy laminate glass fibre
The surface of cloth coats paint.
Further, copper mesh uses the fine copper net of 80 mesh 0.12mm thickness.
Further, metal joint uses the stainless steel material of copper coating.
Further, metal joint passes through between copper mesh together with the silver solder silver soldering of argentiferous 40%.
Further, the thickness of epoxy laminate glass fabric is not less than 0.5mm.
A kind of carbon fiber covers application of the copper mesh composite material as antenna radiator, thes improvement is that: will be above-mentioned
Carbon fiber covers copper mesh composite material as antenna radiator.
Further, heavy caliber fine thread connection type is used between each section of carbon fiber round tube.
The beneficial effects of the present invention are:
Carbon fiber disclosed in this invention covers copper mesh composite material, and main stress layer is the carbon fibre material of internal layer, middle layer copper
Electric action has been netted, the material property that carbon fiber density is low, intensity is high has not only been remained, but also has improved the electric conductivity of carbon fiber.Most
The epoxy laminate glass fabric of outer layer and its surface paint are nonmetallic materials, electromagnetic signal can be radiated in guarantee copper mesh
While going out, moreover it is possible to protect copper mesh, it is prevented to be oxidized and corrode.
Carbon fiber disclosed in this invention covers copper mesh composite material, copper mesh using 80 mesh 0.12mm thickness fine copper net performance compared with
It is good, both increase the usage amount of copper mesh to greatest extent, improves the electric conductivity of composite material, and prevent copper mesh overstocked, be wound in
Overtension when type, influences shaping round tube.Metal joint uses the stainless steel material of copper coating, and the corrosion resistant of connector can be improved
Corrosion, and prevent thread biting locking.Metal joint is electrical by guaranteeing together with the silver solder silver soldering of argentiferous 40% between copper mesh
Conducting.It also coats when coating epoxy laminate glass fabric, while the weld between metal joint and copper mesh, with
Prevent weld from aoxidizing.
Presently disclosed carbon fiber covers application of the copper mesh composite material as antenna radiator, technical feasibility, and method is clear
It is clear, it provides that a kind of intensity is high, antenna radiator of good conductivity, improves the performance and quality of antenna product, be particularly suitable for
It is used in the occasion more demanding to antenna weights, mechanical strength such as vehicle-mounted, boat-carrying, airborne.
Presently disclosed carbon fiber covers application of the copper mesh composite material as antenna radiator, each section of carbon fiber round tube it
Between be electrically connected using heavy caliber fine thread connection type, not only electric conductivity is stable, reliable, and appearance is also more beautiful
It sees, is compact.
