Abstract

The utility model discloses an optical cable reinforced core, comprising a plurality of composite fiber cores, a cladding housing and a resin, wherein the plurality of composite fiber cores comprise aramid fiber, the cladding housing clads the plurality of composite fiber cores therein, between the plurality of composite fiber cores and the cladding housing there is provided the resin, the composite fiber cores are made of aramid fibers, carbon fibers and polyethylene fibers, the cladding housing is prepared by a material containing polyolefin, nylon and polypropylene, and the resin is epoxy resin. The optical cable reinforced core is simple in manufacture process, does not generate environment pollution, is better in mechanical property than glass fiber, and can satisfy the demands of indoor optical cable arrangement.

Description

Optical cable strengthening core
Technical field
The utility model relates to the optical cable field, relates in particular to a kind of optical cable 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 optical cable strengthening core with the composition fiber that the utility model is intended to propose a kind of.
Embodiment according to the utility model proposes a kind of optical cable strengthening core, comprises several composition fiber cores, coats shell and resin.Comprise aramid fiber in several composition fiber cores.Coat shell several composition fiber cores are wrapped in wherein, and resin is filled in several composition fiber cores and coats between the shell.
In one embodiment, the composition fiber core comprises aramid fiber, carbon fibre.In another embodiment, the composition fiber core comprises aramid fiber, carbon fibre and polyethylene fibre.
In one embodiment, coat shell and contain polyolefin.In another embodiment, coat shell and contain polyolefin, nylon and polypropylene.
In one embodiment, resin uses epoxy resin.
The optical cable strengthening core manufacture process of the utility model is simple, does not produce environmental pollution, and its mechanical property is superior to spun glass simultaneously, can satisfy the needs that inside cable is laid.
Description of drawings
Fig. 1 has disclosed the structural drawing according to the optical cable strengthening core of an embodiment of the utility model.
Embodiment
With reference to shown in Figure 1, the optical cable strengthening core 100 of the utility model comprises: several composition fiber cores 102, coating shell 104 and resin 106.Several composition fiber cores 102 comprise aramid fiber.In one embodiment, composition fiber core 102 comprises aramid fiber and carbon fibre, and in another embodiment, composition fiber core 102 comprises aramid fiber, carbon fibre and polyethylene fibre.Coating shell 104 is wrapped in several composition fiber cores 102 wherein.In one embodiment, coating shell 104 adopts polyolefine material to make.In another embodiment, in coating shell 104, also contain nylon and polypropylene (PP).Resin 106 is filled in several composition fiber cores 102 and coats between the shell 104.In one embodiment, resin 106 is an epoxy resin.
The manufacture process of the optical cable strengthening core 100 of the utility model is following:
The composition fiber core that at first prepares aramid fiber, carbon fibre and polyethylene fibre.Carry out ultra-violet curing at composition fiber core outerwrap epoxy resin and to epoxy resin then.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 one again and coats shell outside epoxy resin.The main material that coats shell 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 optical cable 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 optical cable strengthening core of the utility model is following:
Pulling strengrth>=1650Mpa, tensile modulus of elasticity>=55Gpa, breaking elongation≤1.6%.
The optical cable strengthening core manufacture process of the utility model is simple, does not produce environmental pollution, and its mechanical property is superior to spun glass simultaneously, can satisfy the needs that inside cable is laid.
