Description
Technical field
The present invention relates to composite building material, sensor, engineering detecting and Solid Mechanics field, more particularly to one
Plant high-performance small pre-stress thermoplastics type's Intelligent optical fiber rod and preparation method thereof.
Background technology
The Brillouin scattering of inside of optical fibre is sensitive to stress and temperature.Around this principle, there is more ripe dividing
Cloth optical fiber sensing technology.The characteristics of technology is continuously to measure rather than traditional point measurement, therefore its application and popularization,
The revolutionary technological break-through in engineering detecting field and sensor application field will be caused.Japan, Canada, Germany and in
State all develops Brillouin scattering optical fiber parsing instrument in succession, is commonly called as Guang Nayi.Optical fiber used is very slim and frahile, it is impossible to adapt to extensive
Engineering construction environment, it is therefore desirable to be protected by.
Although general communication cable has thick and heavy peripheral protective layer, but the transmission and heat transfer stress all completely cut off
, be not suitable for making sensor and use.And bare fibre and tightly packaged fiber are all very fragile, in the situation for being built in concrete component,
Pour, operation of vibrating can make fibercuts；And it is buried in side slope exploratory trench situation, laying backfilling process can destroy optical fiber；Attached
Formula installation situation in, as careless manipulation at any time can fracture failure.Accordingly, it would be desirable to optical fiber is consolidated in advance in engineering
Due in suitable engineering material, composite wire rod is made, to construct.This wire rod need with certain rigidity and
There is certain flexibility, be provided simultaneously with intensity higher.In addition, this composite wire rod, should also have preferably reprocessing
Characteristic, so as to fragmented transport, field joint and formation termination attractive in appearance.
Address that need, we have now been developed glass fiber cable intellectual rib, its preparation method is by embedded fibers
In glass fibre FRP material.（Wherein FRP is the abbreviation of fiber reinforced polymer, i.e. fibre-reinforced high molecular material
Material, finished product is a kind of composite.）
FRP forms the continuous muscle material of diameter 6mm or so, can be used as sisters' muscle（By glass fiber cable intellectual rib and building iron
Muscle is arranged side by side）, it is also possible to serve as replacement muscle（Replaced building iron）.This FRP products have the following disadvantages：
Although the 1, tensile strength is high, belong to fragile material, therefore it is bad to curve performance, generally in transport, minimum bend half
1.5 meters of footpath, and in engineering is laid, minimum bending radius is limited in 1.75 meters, it is impossible to adapt to the big work of less or flexibility
Journey component；
2nd, thermoset material is belonged to, therefore secondary operation is done in inconvenience；
3rd, the material of pultruded technique added with globality stearic acid release agent zinc, therefore inconvenient cementing connection, also inconvenient end
Cementing fixation, and draw and twine technique that optical fiber can be caused to be slightly curved is lax, cause excessive optical attenuation, influence the sensitivity of sensor
Property.
Therefore, we on this basis, developed a kind of high-performance small pre-stress thermoplastics type's Intelligent optical fiber rod and its
Preparation method.
The content of the invention
The purpose of the present invention is that the shortcoming and defect for overcoming prior art to exist, there is provided a kind of high-performance small pre-stress
Thermoplastics type's Intelligent optical fiber rod and preparation method thereof.
The object of the present invention is achieved like this：
1st, using small pre-stress technology
First, optical fiber is too slim and frahile, it is impossible to adapt to extensive engineering construction, thus by optical fiber curing 6mm or so polythene materials,
In the thermoplastic materials such as polytetrafluoroethylmaterial material, the intellectual rib material with optical fiber is formed；
Secondly because optical fiber can not sense contraction strain, i.e., can not experience compression, be this in solidification, it is less with one
Power traction optical fiber, is allowed to be in a kind of elastic stretching state, and after the thermoplastic material solidification on periphery, optical fiber still has 3000 μ left
Right stretcher strain；Using 3000 μ as zero point during measurement, in actual applications, in the event of compression, then the reading of optical fiber
Drop to 3000 below μ, optical fiber is still within extended state；This small pre-stress just assigns optical fiber when thermoplastic material solidifies,
And optical fiber is in small pre-stress state always, micro-stretching state is kept in geometric shape.
2nd, using thermoplastic materials
Conventional technology is solidified using GFRP materials, once solidification, it is impossible to it is molded again.The present invention uses polyethylene material
The thermoplastic materials such as material or polytetrafluoroethylene (PTFE)；Process is that master batch is heated and softened, and pultrusion, in the same of shaping
When, the optical fiber of small pre-stress, that is, the optical fiber tightened will be applied with, it is placed in the centre of club-shaped material, and continuous pultrusion shape
Into wire rod.Solidify after being cooled down with cold water.
The muscle material that so thermoplastic solidify to form, can form joint attractive in appearance, by optical fibre welded parts again with post forming
Bag is the bare fibre for striking off diaphragm in muscle material internal optical fiber fusion point, and covering 40 with thermoplastic protects.Muscle material connecting portion is smooth, etc.
Diameter（Also thicker diameter can be used）, configuration is regular, attractive in appearance.
The thermoplastic material of post forming can also form the termination of grace attractive in appearance, and its principle is with to reinvent tie point similar.
Specifically：
First, high-performance small pre-stress thermoplastics type Intelligent optical fiber rod（Abbreviation optical fibre rod）
This intelligent rod includes sensor fibre and thermoplastics type's barred body；
Covering outside sensor fibre has thermoplastics type's barred body.
Described sensor fibre is a kind of telecommunication optical fiber for being applied with small pre-stress.

2nd, the preparation method of high-performance small pre-stress thermoplastics type Intelligent optical fiber rod
1. on draw-gear, the telecommunication optical fiber that will be wound on bobbin winder bracket is drawn and is fixed on traction wheel by contact roller, is compressed
Governor motion controls the elastic of contact roller, and regulation is applied to the size of the microstress of telecommunication optical fiber, obtains Intelligent optical fiber；
2. on thermoplastic shaping streamline, Intelligent optical fiber and thermoplastic material master batch enter from main feed mouthful, other materials from it is auxiliary enter
Material mouth enters；
3. in working chamber, by heating, shaping and cooling etc. operation, Intelligent optical fiber by flowing in whole thermoplastic material bags
Wrap up in；
4. a kind of high-performance small pre-stress thermoplastics type intelligence light being made up of Intelligent optical fiber and thermoplastics type's barred body is obtained in discharging opening
Fine rod；
5. by measuring length, it is wound into a roll；

The present invention has following advantages and good effect：
1）Small pre-stress is applied with, optical fiber will not bend, gauffer, it is ensured that larger light loss will not occur, that is to say, that avoid
Light blocking, keeps light path unimpeded；
2）By mobile working state, using 3000 μ as the work zero point of sensing element, compression is set to show as negative drawing
Stretch, solve the problems, such as that optical fiber can not sense compression strain；
3）Due to using thermoplastic materials, in use, matrix can be again melted by heating and find out fiber stub；Can
Termination attractive in appearance is formed with by melting again；Connection transition joint can again be melted, make small pre-stress thermoplastics type's optical-fiber intelligent
Muscle recovers smooth form in joint, and recovers mechanics bearing capacity.
4）Thermoplastic materials can multiple heating and melting repeatedly, multiple reshaping, therefore easy to use, structure is attractive in appearance, jail
Solid, it is reliable.
