Accompanying drawing explanation
Fig. 1 is the structural representation of novel guiding fiber one preferred embodiment processed of the utility model;
In accompanying drawing, the mark of each parts is as follows: 1, optical fiber, 2, polyimide coating, 3, carbon fiber strengthens liquid crystal polymer and strengthen protective layer.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that, protection domain of the present utility model is made to more explicit defining.
Refer to Fig. 1, the utility model embodiment comprises:
A guiding fiber processed, comprising: optical fiber 1, on described optical fiber 1 outside surface, be coated with a polyimide coating 2, and in polyimide coating 2 peripheries, be coated with a carbon fiber and strengthen liquid crystal polymer enhancing protective layer 3.
Optical fiber 1 external diameter that is coated with polyimide coating 2 is 0.155mm.The Applicable temperature of polyimide coating 2 is-60
oc is to+300
oc, as the primary coating of optical fiber 1, shields to optical fiber 1.
Described optical fiber 1 is the insensitive optical fiber 1 of G657 bending loss, and optical fiber 1 diameter is 0.125mm.
The insensitive optical fiber 1 of described G657 bending loss comprises that minimum bending radius is the optical fiber that the optical fiber of 10mm, optical fiber that minimum bending radius is 7.5mm and minimum bending radius are 5mm.
Along with Access Network and FTTH development, for optical fiber, new requirement is also proposed, at this time G652 optical fiber traditional, a large amount of uses can not meet user demand completely in some occasion, so the Dec of 2006, ITU has released the standard of new G657 bending loss insensitive single-mode fiber, and G657 optical fiber is divided into G657A and G657B two classes.G657A need be completely compatible with conventional G652D optical fiber, and minimum bending radius is 10mm; G657B optical fiber is not imposed with completely compatible with G652D optical fiber, but in bending property, has higher requirement, and minimum bending radius is 7.5mm.Development along with G657 fiber optic applications, the index of bending loss is proposed to more and more higher requirement, in order to adapt to new market development, in October, 2009, ITU has increased the new criteria that minimum bending radius is 5mm in G657 standard, like this, G657 optical fibre packages has contained the kind of three kinds of minimum bending radius, and this class is applicable to optical fiber particularly suitable without the bending radius high request occasion when guiding fiber processed need be wrapped in moulding winding.
The diameter that described carbon fiber strengthens liquid crystal polymer enhancing protective layer 3 is less than or equal to 1mm.
Carbon fiber strengthens the preferred embodiment 1 that liquid crystal polymer strengthens protective layer 3 compositions: comprise that following one-tenth is grouped into: liquid crystal polymer 40%, carbon fiber 30%, thermal stabilizer 3%, light stabilizer 2%, nanoclay 4%.
Carbon fiber strengthens the preferred embodiment 2 that liquid crystal polymer strengthens protective layer 3 compositions: comprise that following one-tenth is grouped into: liquid crystal polymer 50%, carbon fiber 50%, thermal stabilizer 10%, light stabilizer 5%, nanoclay 6%.
Carbon fiber strengthens the preferred embodiment 3 that liquid crystal polymer strengthens protective layer 3 compositions: comprise that following one-tenth is grouped into: liquid crystal polymer 45%, carbon fiber 40%, thermal stabilizer 6%, light stabilizer 3%, nanoclay 5%.
Carbon fiber strengthens liquid crystal polymer and strengthens the intrinsic intrinsic property that protective layer 3 not only has material with carbon element, has again the soft processibility of textile fibres concurrently, is fortifying fibre of new generation.Compare with traditional glass fibre, Young modulus is that they are more than 3 times; It is compared with aramid fiber, and not only Young modulus is its 2 times of left and right, and insoluble not swollen in organic solvent, acid, alkali, and corrosion stability is transcendent.
The mechanical property that carbon fiber strengthens liquid crystal polymer is good, and friction factor and rate of wear are low, endurance, and thermal expansivity is little, high this 250Mpa of its tensile strength.It is to adopt extrusion process directly to extrude on the optical fiber that has polyimide coating 21 of primary coating as optical fiber enhancing protective layer that carbon fiber strengthens liquid crystal polymer, and its equipment is the high temperature extruding production line of the hard-pressed bale layer of traditional tightly packaged fiber.
The reason that adopts carbon fiber enhancing liquid crystal polymer to strengthen protective layer as optical fiber comprises:
(1) thermal expansivity of liquid crystal polymer is than little 1 order of magnitude of general plastics, this is as optical fiber, to strengthen the pacing items of protection coating materials, it can make when temperature significantly changes, do not cause the thermal expansivity of optical fiber itself and hard-pressed bale plastic layer differ too large and be subject to stress, thereby affect serviceability.(2) liquid crystal polymer has the mechanical property of high strength, high-modulus; it can meet or exceed the physical strength after tens percent glass fibre enhancing and the level of modulus for unskilled labor engineering plastics under the state not strengthening, thereby the utility model has enough mechanical protection abilities with the guiding fiber processed that carbon fiber reinforced liquid crystal polymer strengthens protective layer as optical fiber.(3) liquid crystal polymer can be 300
othe medium-term and long-term use of temperature range of C.(4) liquid crystal polymer has fabulous radioresistance and anti-flammability, can knock down the flame and no longer proceed burning, thereby it is the best special plastic of fire savety, can make guiding fiber processed apply in various harsh military environments.
The novel guiding fiber processed of the utility model is usingd carbon fiber reinforced liquid crystal polymer as strengthening protective layer, has high-intensity heat-resisting quantity and anti-flammability, compares with traditional guiding fiber processed, and its function admirable, makes simple, applied widely.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model instructions and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
