The composite fiber reinforced core has the characteristics of being small in density, light in specific gravity, high in strength, great in modulus, and small in extension, is obviously better in mechanical property than the glass fiber, and can satisfy the demands of indoor optical cable arrangement.
Description
Technical field
The utility model relates to the optical cable field, relates in particular to a kind of composition fiber strengthening core.
Background technology
In order to accelerate informatization, need to strengthen the laying of fiber optic cable networks, advance construction and the development that Fiber to the home (FTTH).Optical cable comprises optical fiber, strengthening core and sheath.The strengthening core of the use in the optical cable mainly comprises spun glass strengthening core and metal strengthening core.For inside cable, require to possess following several characteristics in indoor laying: well flexibility, stronger stretch-resistance, certain side impact resistance, have anti-thunderbolt ability.
The metal strengthening core has metallic character, does not possess anti-thunderbolt ability, is not suitable for using as inside cable.
The spun glass strengthening core have stretch-resistance, corrosion-resistant, can prevent thunderbolt, simultaneously,, be in inside cable, to use more strengthening core at present because price is lower.But the flexibility of spun glass strengthening core is poor, fractures easily, weight is bigger., house wiring, cause the basic role of strengthening core to completely lose when constructing often easily because be bent and produced and fracture by knotting.Another shortcoming of spun glass strengthening core is that the environmental pollution that causes in process of production is bigger, and spun glass produces a large amount of dust in process of production, and the meeting serious environment pollution also can cause very big injury to human body.
The utility model content
It is main composition fiber strengthening core with the composition fiber that the utility model is intended to propose a kind of.
According to an embodiment of the utility model, a kind of composition fiber strengthening core is proposed, comprise composition fiber core bundle, elastic layer and overcoat.Composition fiber core bundle comprises the composition fiber core of several carbon fiber-containings and pbo fiber.Elastic layer is coated on outside the composition fiber core bundle.Overcoat is wrapped in outside the elastic layer.
In one embodiment, the composition fiber core also comprises polyethylene fibre.
In one embodiment, elastic layer comprises resin, such as epoxy resin.
In one embodiment, overcoat contains polyolefin.In another embodiment, overcoat contains polyolefin, nylon and polypropylene.
The composition fiber strengthening core of the utility model possesses that density property is little, light specific gravity, intensity is high, modulus is big, elongation is little characteristic, and mechanical property obviously is superior to spun glass, can satisfy the needs that inside cable is laid.
Description of drawings
Fig. 1 has disclosed the structural drawing according to the composition fiber strengthening core of an embodiment of the utility model.
Embodiment
With reference to shown in Figure 1, the composition fiber strengthening core 100 of the utility model comprises: composition fiber core bundle 102, elastic layer 104 and overcoat 106.Composition fiber core bundle 102 comprises the composition fiber core 121 of several carbon fiber-containings and pbo fiber.
PBO is the abbreviation of polyparaphenylene's benzo dioxazole.Pbo fiber is to be made through fiber spinning from crystalline state by the PBO polymkeric substance, uses with carbon fibre to make the composition fiber core have higher specific strength, specific modulus and heat-proof combustion-resistant performance.In one embodiment, composition fiber core 121 also comprises polyethylene fibre except carbon fibre and pbo fiber.Elastic layer 104 is coated on outside the composition fiber core bundle 102.In one embodiment, elastic layer 104 comprises resin.Resin relatively more commonly used is an epoxy resin.Overcoat 106 is wrapped in outside the elastic layer 104.In one embodiment, overcoat 106 adopts polyolefine material to make.In another embodiment, also contain nylon and polypropylene (PP) in its external sleeve 106.
The manufacture process of the composition fiber strengthening core 100 of the utility model is following:
The composition fiber core that at first prepares carbon fibre, pbo fiber and polyethylene fibre.The carbon fibre that the utility model adopted, pbo fiber and polyethylene fibre all are that density property is little, light specific gravity, intensity is high, modulus is big, elongation is little fiber; With these fibers as matrix; Get into the oven dry of die hole extrusion stretching behind the modified polyester complex liquid dipping high through excess temperature, that pulling strengrth is big and be made as rhabodoid; Form the composition fiber core, with the soft composition fiber core bundle that becomes of several composition fiber cores.At composition fiber core bundle outerwrap elastic layer, an example of elastic layer is a resin then, such as epoxy resin, and epoxy resin is carried out ultra-violet curing.Because hardening becomes fragile behind the epoxy resin cure, possibly have the unevenness of coating simultaneously, thereby the surface of epoxy resin is easy to generate powdery granule, these particles cause damage in follow-up technological process easily.Therefore the utility model coats an overcoat again outside the elastic layer that epoxy resin forms.The main material of overcoat is a polyolefin, can also add nylon and polypropylene (PP), makes through extrusion molding.The stretch modulus of polyolefine material is big, makes the flexibility of whole composition fiber strengthening core increase, and bending resistance promotes, and meets the demand of inside cable more.Simultaneously, when polyolefine material reached more than 150 ℃ in temperature, the sheath that a kind of material and optical cable can be melted in the surface combined together, to promote the overall mechanical properties of optical cable.
The mechanical property of the composition fiber strengthening core of the utility model is following:
Pulling strengrth>=1698Mpa, tensile modulus of elasticity>=60Gpa, breaking elongation≤2.8%.
The bending radius of the optical cable that the composition fiber strengthening core of employing the utility model is processed can reach 0.5mm-1.0mm; Under short-term/long-term pulling force 80N/40N situation; Fibre strain has only 0.3 and 0.15 respectively, and cable jacket does not have visual cracking when stretching simultaneously, thus embodied comprehensively the anti-folding of this strengthening core, bending radius little, with performances such as the oversheath associativity is good; The optical cable that contrast FRP and KFRP process; The optical cable that adopts this product not only cost performance is high, and environmental protection, is applicable to more and registers one's residence and house wiring
The composition fiber strengthening core of the utility model possesses that density property is little, light specific gravity, intensity is high, modulus is big, elongation is little characteristic, and mechanical property obviously is superior to spun glass, can satisfy the needs that inside cable is laid.
