Description

Technical Field [0001] The present invention relates to a fiber yarn for a civil engineering stiffener,

More particularly, the present invention relates to a fiber yarn of a civil engineering reinforcing material, and more particularly to a fiber yarn of a civil engineering stiffener which is excellent in strength and durability but is made of carbon fiber, glass fiber, (Hereinafter referred to as "carbon fiber") coated on a surface of a synthetic resin material which protects the carbon fiber safely while having good flexibility, and a manufacturing apparatus for manufacturing the same.

Generally, various kinds of roads will be improved in waterproof performance, and the reinforcing materials for civil works made of fibers are used to reinforce the overall strength while suppressing the cracks in the roads and enhancing the road durability.

That is, in order to flatten the road during the road construction, the existing ground is excavated or filled, and then the flat work is carried out, and the asphalt mortar or the concrete mortar is laid on the ground. In such a construction, There is a problem that cracks are formed in the mortar packed on top of it. Therefore, in order to prevent this, it is necessary to stack the civil engineering reinforcements together with the gravel.

Such civil reinforcing materials have been conventionally proposed in various forms as fabrics made of a mat or the like of a fabric or a nonwoven fabric and are actually widely used.

Among them, conventionally proposed civil engineering reinforcing material is Korean Utility Model Registration No. 0227589, which is composed of a reinforcing member of a metal material having a predetermined width and a net shape, and upper and lower asphalt layers formed on upper and lower sides of the reinforcing member Sand attached to the upper surface of the upper asphalt layer, and release paper adhered to the lower surface of the lower asphalt layer.

However, such a conventional structure has a disadvantage in that it is made of a metallic material, that is, a mat, provided between the upper and lower asphalt layers, but is easily corroded because it is made of a metal material.

Another structure conventionally proposed is Korean Patent Publication No. 2006-0031029.

It has been proposed that a reinforcing material in which carbon fibers and heating wires which generate heat by application of external power are arranged in order or in a predetermined order in one direction and glass fibers are arranged and crossed in the other direction to form a grid

However, such a conventional structure is advantageous in that durability and strength are strong due to the characteristics of carbon fibers and glass fibers formed in the form of a net, but they are weak against external shocks, It was easily broken or broken.

In particular, carbon fibers and glass fibers have a problem in that it is structurally difficult and difficult to weave in the form of a net because the fibers are broken without being bent within a certain angle.

Another conventional configuration is Korean Patent Publication No. 2006-0073260.

This is because the glass fiber roving yarn is fed from the krill band to the glass fiber roving yarn to be inclined, the glass fiber roving yarn is weighed on the upper portion of the warp yarn, Which is made by a method of forming a lattice-shaped bonded structure by using a warp knitting yarn, coating it with a bitumen, treating a surface of a coated geogrid product with a pressure-sensitive adhesive, and bonding a woven fabric or a non- And a manufacturing method thereof.

However, the strength of the nonwoven fabric or the woven fabric itself is so low that the reinforcing efficiency of the road is lowered, and the weft and the warp are not firmly combined with each other.

In recent years, civil engineering reinforcing materials using carbon fiber or glass fiber with excellent properties have been proposed and widely used, which has been proposed by the present applicant.

Carbon fiber containing more than 90% of carbon is a new material fiber made by heating and carbonizing organic fiber in inert gas. It is lighter than metal but has better strength and elasticity than metal, and has good heat resistance and conductivity. There are many advantages that it does not exist.

Due to these advantages, carbon fiber is widely used in fishing rods, golf clubs, tennis racquets, aircraft, wind power equipment, automobile parts, civil engineering construction materials and various carbon fiber reinforced composite materials.

In addition, mineral fibers such as glass fiber and stone fiber, which are made of glass or stone raw material, are excellent in mass production and commercial application, and are widely used in various industrial fields because of their high cost efficiency.

However, since carbon fibers and mineral fibers have excellent characteristics and advantages of the material, they have a disadvantage that they break easily when they are bent over a certain angle. Therefore, There was a limit.

That is, since carbon fibers of carbon fiber only have difficulty to be woven into the fabric of civil engineering reinforcements due to the characteristics of their own materials, they can be arranged in a lattice shape at regular intervals as shown in the above- There is a structural problem that must be formed.

Particularly, conventionally proposed methods for producing glass fiber or carbon fiber are methods for imparting conductivity to the surface, that is, a conventionally proposed Korean Patent No. 10-0715553 (conductive glass fiber and method for manufacturing the same) There has been proposed a method of sizing glass fibers by forming a conductive layer containing an electroconductive polymer as an effective component by a method of imparting conductivity to glass fibers.

The above-mentioned pre-registered invention provides a glass fiber which can provide antistatic property or electromagnetic shielding property and can easily control resistance, or a conductive polymer is applied on the surface of a conventional glass fiber used for various applications such as extrusion and injection, To provide a glass fiber whose resistance is controlled. However, there is a problem in that it is impossible to apply the glass fiber for use in civil engineering, which is required in the present invention.

Korean Patent No. 10-1038054 (metal coated inorganic fiber and its manufacturing apparatus) is coated with a non-conductive inorganic fiber to give electrical conductivity. However, even though this leads to improvement of electric conductivity, There was a limit to use.

In another type of conventional patent document 10-0534295, carbon fibers are coated on carbon fibers such as natural fiber yarn, mineral yarn and synthetic fiber yarn to produce a carbon-coated fiber yarn, We fabricate surface and top heating elements that weave textile fabric without coating on weaving and carbon fiber textile yarn as weft, weave weaving fabric with uncoated fiber and weave on fabric surface with insulating coating to convert electric energy into thermal energy. It has been proposed.

However, since this method also allows the fiber yarn to be coated with another material, the fiber yarn is coated with carbon black, which is unsuitable for the civil works required in the present invention.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a carbon fiber yarn, which is made of a carbon fiber yarn in which the flexibility is added to the carbon fiber excellent in durability and strength, And which can be used as reinforcing materials for various civil engineering works.

Another object of the present invention is to provide a method of coating a surface of a carbon fiber yarn woven with a mat type civil engineering reinforcing material with a synthetic resin material having excellent flexibility by continuously and automatically producing the same using a mechanical device, And a reinforcing member for reinforcing the reinforcing member.

In order to accomplish the above object, the present invention provides a carbon fiber which is made of carbon fiber, glass, stone or the like as a main raw material while being manufactured in a thin thread form, and a flexible material of a synthetic resin coated on the surface of the carbon fiber, The present invention includes a method of manufacturing a fiber yarn composed of a sheath that protects carbon fiber from external impact and imparts flexibility to the fabric so that the fabric of the mat type civil engineering reinforcement can be woven using the fiber yarn.

The present invention also provides a method of manufacturing a carbon fiber yarn, which is coated with a synthetic resin outer skin, using a mechanical and automated manufacturing apparatus, comprising a body into which molten synthetic resin material can be charged, And a carbon fiber supply member for supplying carbon fibers to the nozzle at a rear side of the nozzle body so as to be continuously supplied to the nozzle body, The outer surface of the molten synthetic resin is automatically coated on the surface of the carbon fiber.

The fiber yarn according to the present invention has the effect of woven the fabric of the civil engineering reinforcing material having various shapes by integrally coating the outer surface of the synthetic resin material having excellent flexibility on the surface of the carbon fiber made of the carbon material.

That is, a flexible synthetic resin is coated on the surface of a carbon fiber which is made of a carbon material and forms a thin thread, and a fiber yarn having a thickness of 400 to 10,000 d (denier) is formed, It is possible to set up.

Therefore, the fabric of the civil engineering reinforcing material woven with the fiber yarn has a high elastic modulus and a high tensile strength, so that it has excellent durability and strength to prevent disconnection of the fiber yarn and prevents reflection cracks and wheel locus and shear deformation of the new packaging surface And it is also possible to prevent the reduction of the thickness of the package due to the expansion of the load transmitted to the surface.

In addition, the present invention can be continuously and automatically manufactured by using a mechanical device suitable for manufacturing the fiber yarn, so that productivity can be expected to be improved. In addition, It is possible to have an effect that can be achieved.
