Description
본 발명은 낚싯대의 제조방법에 관한 것으로서, 특히 낚시대의 원주방향 물성을 향상시킨 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a fishing rod, and more particularly, to a manufacturing method of improving the circumferential physical properties of a fishing rod.
보강섬유와 수지로 구성된 프리프레그를 이용하여 낚싯대를 제조할때에는 낚싯대의 기계적인 물성을 고려하여 프리프레그의 종류를 선택하게 된다. 낚싯대의 기계적인 물성은 낚싯대의 굴곡특성을 위해서 길이방향 물성과 낚싯대 길이에 수직한 방향, 즉 낚싯대의 원주방향의 물성도 함께 고려된다.When manufacturing a fishing rod using a prepreg composed of reinforcing fiber and resin, the type of prepreg is selected in consideration of the mechanical properties of the fishing rod. The mechanical properties of the fishing rod are also considered for the bending properties of the fishing rod along with the longitudinal properties and the properties perpendicular to the length of the fishing rod, ie the circumferential properties of the fishing rod.
낚싯대에 프리프레그를 사용할 경우에 일방향 프리프레그, 일방향 프리프레그에 얇은 유리섬유 스크림 직물이 접착된 제품 또는 보강섬유가 직조된 직물로 구성된 제품의 형태로 사용하게 되며, 이러한 프리프레그들은 단독 또는 혼합하여 낚싯대를 제조하게 된다.When using a prepreg on a fishing rod, it is used in the form of a one-way prepreg, a product in which a thin glass fiber scrim fabric is bonded to the one-way prepreg, or a product composed of a woven fabric of reinforcing fibers. The fishing rod will be manufactured.
보강섬유와 수지로 구성된 프리프레그를 사용하는 낚싯대의 기본 제조공정은 재단공정, 롤링공정, 랩핑공정 및 경화공정으로 이루어진다.The basic manufacturing process of a fishing rod using a prepreg composed of reinforcing fibers and resin is composed of a cutting process, a rolling process, a lapping process, and a curing process.
재단공정은 프리프레그를 적정 길이로 자르는 공정이다. 재단된 프리프레그를 심봉(맨드렐)에 감는 공정을 롤링공정이라 한다. 롤링공정후 심봉에 감겨진 프리프레그 위에 열수축 필름을 나선형으로 감는 것을 랩핑(wrapping)공정이라 하며, 랩핑공정후 열을 가하여 프리프레그에 있는 수지를 열경화시키는 것을 경화공정이라 한다.The cutting process is a process of cutting the prepreg to an appropriate length. The process of winding the cut prepreg on the mandrel is called a rolling process. The spiral wrapping of the heat-shrinkable film on the prepreg wound on the core rod after the rolling process is called a wrapping process. The curing of the resin in the prepreg by applying heat after the wrapping process is called a curing process.
대한민국 실용신안 공개 제1999-33759호에는 낚싯대의 물성증진과 외관의 수려함을 위하여 낚싯대 로드에 티타늄재의 와이어를 낚싯대의 길이방향 또는 나선형 권취에 의한 X형 감기 등으로 금속 와이어를 낚싯대의 표면에 감는 방법이 제안되어 있다.In Korea Utility Model Publication No. 1999-33759, a metal wire is wound around the surface of a rod by X-axis winding of a rod of titanium material on the rod for the purpose of improving the physical properties of the rod and the appearance of the rod. A method is proposed.
이러한 방법은 금속 와이어의 방향에 따라서 물성 증진의 효과가 나타나지만, 낚싯대 로드를 완성시킨후에 별도의 금속 와이어를 권취하는 공정을 수행함으로 제조 생산성이 저하되고 원가가 높아지는 단점이 있다. 또한 낚싯대의 길이방향으로 금속 와이어를 권취할 경우 낚싯대의 원주방향의 물성증진이 이루어지지 않으며, X형 감기에 의해서도 낚싯대의 원주방향의 물성증진은 미약하다.This method has the effect of improving the physical properties according to the direction of the metal wire, there is a disadvantage that the manufacturing productivity is lowered and the cost is increased by performing a process of winding a separate metal wire after completing the rod rod. In addition, the winding of the metal wire in the longitudinal direction of the fishing rod does not increase the circumferential properties of the fishing rod, and the X-winding is also weak in the circumferential properties of the fishing rod.
또한 금속와이어를 롤링공정을 마친 프리프레그의 표면에 권취할 경우에는 경화공정중에 수지 점도의 저하가 발생하게 된다. 이때 일정하중으로 권취된 금속와이어에 의하여 기존 보강섬유의 배열이 흐트러져서 낚싯대의 강도가 저하되는 문제점이 있다.In addition, when winding a metal wire on the surface of the prepreg which completed the rolling process, the resin viscosity will fall during a hardening process. At this time, the arrangement of the existing reinforcing fibers is disturbed by the metal wire wound by a constant load, there is a problem that the strength of the fishing rod is reduced.
본 발명의 목적은 기존의 낚싯대 제조공정을 유지하면서도 낚싯대의 원주방향의 물성을 크게 증진시킬 수 있는 낚싯대의 제조방법을 제공하는데 있다.An object of the present invention is to provide a method of manufacturing a fishing rod that can greatly improve the physical properties of the circumferential direction of the fishing rod while maintaining the existing fishing rod manufacturing process.

본 발명은 낚싯대의 제조방법에 관한 것으로서, 본 발명에 의하면 금속시트가 일표면에 적층된 프리프레그를 금속시트층이 낚싯대의 외표면에 노출되도록 롤링하는 공정을 포함하는 것을 특징으로 하는 낚싯대의 제조방법이 제공된다.The present invention relates to a manufacturing method of a fishing rod, according to the present invention, the manufacturing method of the fishing rod comprising the step of rolling the prepreg in which the metal sheet is laminated on one surface so that the metal sheet layer is exposed to the outer surface of the fishing rod. A method is provided.
또한, 두께가 5∼150㎛인 금속시트가 일표면에 적층된 프리프레그를 금속시트층이 낚싯대의 외표면에 노출되도록 롤링하는 공정을 포함하는 것을 특징으로 하는 낚싯대의 제조방법이 제공된다.In addition, there is provided a fishing rod manufacturing method comprising a step of rolling a metal sheet layer having a thickness of 5 ~ 150㎛ prepreg laminated on one surface so that the metal sheet layer is exposed to the outer surface of the fishing rod.
또한, 다공성인 금속시트가 일표면에 적층된 프리프레그를 금속시트층이 낚싯대의 외표면에 노출되도록 롤링하는 공정을 포함하는 것을 특징으로 하는 낚싯대의 제조방법이 제공된다.In addition, a method of manufacturing a fishing rod is provided, comprising the step of rolling a prepreg in which a porous metal sheet is laminated on one surface such that the metal sheet layer is exposed to the outer surface of the fishing rod.
이하, 본 발명에 대하여 도면을 참조하여 보다 상세하게 설명하기로 한다. 하기 도면들은 본 발명의 일예를 나타내는 것으로서, 이에 의하여 본 발명은 제한받지 않는다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. The following drawings show an example of the present invention, whereby the present invention is not limited.
본 발명은 금속시트가 일표면에 적층된 프리프레그를 금속시트층이 낚싯대의 외표면에 노출되도록 롤링하는 공정을 포함하는 것을 특징으로 한다.The present invention is characterized in that it comprises a step of rolling a prepreg metal sheet laminated on one surface so that the metal sheet layer is exposed to the outer surface of the fishing rod.
도 1은 본 발명의 금속시트의 바람직한 일예를 나타내는 도면이다. 도 1에서 나타난 바와 같이 본 발명의 금속시트는 다공성이며, 그 모양과 크기는 한정하지 않는다. 본 발명에서는 금속시트를 낚싯대에 적용하여 낚싯대의 원주방향의 물성을 증진시킨다. 보강섬유와 수지로 구성된 프리프레그는 이방성 재료이기 때문에 보강섬유의 방향에 의해서만 물성 증진의 효과가 나타난다. 그러나 본 발명에서는 금속시트를 적용하여 보강섬유에 의한 이방성 물성 특성을 완충하여 낚싯대의 원주방향물성, 즉 섬유 직각방향(90°)의 물성을 증진시킬 수 있는 것이다. 또한, 금속시트를 적용하면 경화공정에서 기존 보강섬유의 배열을 흐트릴 가능성이 없으므로 보강섬유의 배열이 흐트러져서 낚싯대의 강도가 저하되는 문제점을 해결할 수 있다.1 is a view showing a preferred example of the metal sheet of the present invention. As shown in FIG. 1, the metal sheet of the present invention is porous, and its shape and size are not limited. In the present invention, by applying a metal sheet to the fishing rod to enhance the circumferential properties of the fishing rod. Since the prepreg composed of reinforcing fibers and resin is anisotropic material, the improvement of physical properties is shown only by the direction of the reinforcing fibers. However, in the present invention, by applying a metal sheet to buffer the anisotropic physical properties of the reinforcing fibers to improve the circumferential physical properties of the fishing rod, that is, the right angle of the fiber (90 °). In addition, the application of the metal sheet can solve the problem that the strength of the fishing rod is reduced because the arrangement of the reinforcing fibers is disturbed because there is no possibility of disturbing the arrangement of the existing reinforcing fibers in the curing process.
특별히 한정하기 위한 것은 아니지만 금속시트 재질은 예를 들어 티타늄, 알루미늄, 스틸 등의 금속이 있다.Although not particularly limited, the metal sheet material may be metal such as titanium, aluminum, or steel.
본 발명의 금속시트는 두께가 5∼150㎛인 것이 바람직하다. 금속시트의 두께가 너무 두꺼우면 롤링(rolling) 공정을 수행하기 어려우며 롤링후에 외관이 거칠어질 우려가 있다.It is preferable that the metal sheet of this invention is 5-150 micrometers in thickness. If the thickness of the metal sheet is too thick, it is difficult to perform the rolling (rolling) process and there is a fear that the appearance is rough after rolling.
또한, 본 발명의 금속시트는 다공성 금속시트인 것이 바람직한 데 그 이유는, 소재 경화공정에서 다공성을 가진 금속시트가 수지의 유동을 방해하지 않으며 외관면에서도 수려한 장점이 있다. 다공성 금속시트의 구멍의 크기나 모양에 대하여 제한하지 않는다.In addition, it is preferable that the metal sheet of the present invention is a porous metal sheet, because the metal sheet having a porosity in the material curing process does not interfere with the flow of the resin and has an advantage in appearance. There is no limitation on the size or shape of the holes in the porous metal sheet.
도 2는 본 발명의 금속시트가 프리프레그의 일표면에 적층된 상태를 나타내는 바람직한 일예이다.Figure 2 is a preferred example showing a state where the metal sheet of the present invention is laminated on one surface of the prepreg.
예를 들어 에폭시 고형분 : 아세톤의 무게비가 1 : 10인 접착제를 금속시트의 일면 전체 또는 양면 전체에 도포하여 아세톤을 건조시킨 후 금속시트를 프리프레그에 접착시킨다. 이와 같이 금속시트에 접착제를 도포하여 롤링공정을 수행하게 되면, 롤링공정후에도 금속시트가 풀려지지 않게 되어 바람직하다.For example, an epoxy solid: acetone weight ratio of 1:10 is applied to one or both sides of the metal sheet to dry acetone, and then the metal sheet is adhered to the prepreg. As described above, when the rolling process is performed by applying the adhesive to the metal sheet, the metal sheet is not released even after the rolling process.
도 3은 본 발명의 금속시트가 일표면에 적층된 프리프레그를 심봉(맨드렐)에 롤링하는 것을 나타낸 바람직한 일예이다.Figure 3 is a preferred example showing the rolling of the prepreg laminated on one surface of the metal sheet of the present invention to the mandrel (mandrel).
본 발명은 금속시트층이 낚싯대의 외표면에 노출되도록 롤링하는 것을 특징으로 한다. 이와 같이 롤링하면 도 4에서 나타난 바와 같이 금속시트층이 낚싯대의 외표면에 노출되어 금속시트 구멍의 다양한 크기와 모양에 따라 다양한 무늬와 질감을 표현할 수 있게 되어 중후한 금속 질감을 여러 형태로 표현할 수 있어 바람직하다. 금속시트가 낚싯대의 외표면에 노출될수록 원주방향 물성이 증진된다.The present invention is characterized in that the metal sheet layer is rolled to be exposed to the outer surface of the fishing rod. When rolling in this manner, as shown in FIG. 4, the metal sheet layer is exposed to the outer surface of the fishing rod to express various patterns and textures according to various sizes and shapes of the metal sheet holes, thereby expressing a heavy metal texture in various forms. It is preferable. As the metal sheet is exposed to the outer surface of the rod, the circumferential properties are enhanced.
이와 같이 롤링공정을 수행한후 열수축 필름을 감는 랩핑(wrapping)공정 및 경화공정을 거쳐 낚싯대를 제조하게 된다.As described above, the fishing rod is manufactured through a wrapping process and a curing process of winding the heat shrink film after the rolling process.
제조된 낚싯대의 단면구조의 일예는 도 5와 같다. 도 5에서 나타난 바와 같이 금속시트층이 낚싯대의 외표면에 위치하고 그 안쪽으로 프리프레그층이 위치함을 알 수 있다.An example of the cross-sectional structure of the manufactured fishing rod is shown in FIG. As shown in Figure 5 it can be seen that the metal sheet layer is located on the outer surface of the fishing rod and the prepreg layer is located therein.
본 발명은 추가의 공정 설비 없이도 낚싯대의 원주방향으로의 물성을 크게 향상시킬 수 있으며 낚싯대에 금속성을 부여할 수 있다.The present invention can greatly improve the physical properties in the circumferential direction of the fishing rod without additional processing equipment and can impart metallic properties to the fishing rod.
이하, 실시예를 통하여 설명하기로 한다. 단, 본 발명은 하기 실시예에 의하여 한정되지 않는다.Hereinafter, a description will be given through Examples. However, this invention is not limited by the following Example.
〈실시예 1〉<Example 1>
낚싯대 원주방향의 물성을 평가하기 위하여 굴곡시험 시편을 제작하였다. 즉 낚싯대 원주방향에 해당하는 섬유 직각방향(90°방향)으로 시편을 제작하였다. 시편의 규격은 폭 2.54㎝, 길이 9.0㎝의 판상 시편이었다. 판상시편으로 제작한 것은 봉상 시험편보다 그 효과가 분명하게 나타나기 때문이며 섬유방향을 90°로 하여 판상시편을 제작한 이유는 봉상 구조물의 원주방향의 섬유가 90°배열되어 있기 때문이다. 따라서 90°로 배열된 판상시편은 봉상 구조물의 원주방향 물성을 쉽게 판단할 수 있는 시험편이 된다.Flexural test specimens were fabricated to evaluate the properties of the rod in the circumferential direction. That is, the test piece was produced in the fiber perpendicular direction (90 ° direction) corresponding to the circumferential direction of the fishing rod. Specimens of the specimens were plate-shaped specimens of 2.54 cm wide and 9.0 cm long. The reason why the plate specimen was made was that the effect was more pronounced than that of the rod specimen, and the reason why the plate specimen was manufactured with the fiber direction at 90 ° was because the fiber in the circumferential direction of the rod structure was 90 °. Therefore, the plate specimen arranged at 90 ° becomes a specimen that can easily determine the circumferential properties of the rod-shaped structure.
시편은 다음과 같은 방법으로 제조하였다.Specimens were prepared by the following method.
결합제로서 에폭시수지를 사용하여 프리프레그 12장을 적층하고 120∼150℃에서 60-120분 동안 경화시킨다. 다음, 에폭시 고형분과 아세톤을 무게비 1:10으로 혼합하여 제조한 에폭시 용액을 금속시트의 일면에 붓을 사용하여 도포하고 아세톤을 건조시킨 다음 금속시트와 프리프레그 적층물을 접착시켜 시편을 제작하였다.12 sheets of prepreg were laminated using epoxy resin as a binder and cured at 120 to 150 ° C. for 60 to 120 minutes. Next, an epoxy solution prepared by mixing epoxy solids and acetone in a weight ratio of 1:10 was applied to one surface of a metal sheet by using a brush, acetone was dried, and the metal sheet and the prepreg laminate were bonded to prepare a specimen.
시편 제작시 사용되는 프리프레그는 보강섬유로서 인장탄성이 24,000㎏/㎟인 탄소섬유와 수지로서 에폭시 수지가 사용된 일방향 프리프레그[제품명:유에스엔(USN) 075, 에스케이케미칼(주) 제품]를 사용하였다. 또한, 금속시트는 티타늄 재질의 두께 50㎛, 단위면적당 무게가 55g/㎡이고 6각형의 구멍이 뚫려져 있는 금속시트를 사용하였다.Prepreg used for fabrication of specimens is carbon fiber with tensile elasticity of 24,000 kg / mm2 as reinforcing fiber and unidirectional prepreg (product name: USN 075, manufactured by SK Chemicals Co., Ltd.). Used. In addition, a metal sheet having a thickness of 50 μm of titanium, a weight of 55 g / m 2 per unit area, and a hexagonal hole was used.
제작한 시편을 ASTM D 790의 방법(플라스틱 그리고 전기 절연 물질의 굴곡성 시험)에 따라 실시하고 굴곡강성을 측정하여 하기 표 1에 나타내었다.The prepared specimens were subjected to the method of ASTM D 790 (flexibility test of plastic and electrical insulating material) and measured in flexural stiffness.
본 실시예에서 측정한 굴곡강성은 굴곡시험을 통하여 얻어진 하중과 쳐짐변위 곡선의 기울기(slope)를 나타낸 것이다.The flexural stiffness measured in this example shows the slope of the load and deflection displacement curve obtained through the flexural test.
〈비교예 1〉<Comparative Example 1>
금속시트의 효과를 알아보기 위하여 프리프레그만 12장 적층하고 경화시켜 시편으로 제작하였다. 프리프레그만 사용하여 시편을 제작한 것을 제외하고는 실시예 1과 동일하게 실시하였다.In order to examine the effect of the metal sheet, only 12 prepregs were laminated and cured to prepare a specimen. The same procedure as in Example 1 was conducted except that the specimens were prepared using only prepregs.
측정된 굴곡강성은 하기 표 1에 나타내었다.The measured flexural stiffness is shown in Table 1 below.
〈비교예 2〉<Comparative Example 2>
금속시트의 효과를 알아보기 위하여 프리그레그 12장을 적층하고 양쪽 바깥면에 유리섬유 스크림 직물을 적층하여 시편으로 제작하였다. 여기서 시편에 사용되는 유리섬유 스크림 직물은 단위면적당 무게가 25g/㎡인 것을 사용하였다.In order to examine the effect of the metal sheet 12 pieces of pregreg were laminated and glass fiber scrim fabric was laminated on both sides to fabricate the specimen. Here, the glass fiber scrim fabric used for the specimens used had a weight of 25 g / m 2 per unit area.
프리프레그와 유리섬유 스크림 직물만 사용하여 시편을 제작한 것을 제외하고는 실시예 1과 동일하게 실시하였다.The same procedure as in Example 1 was conducted except that the specimens were prepared using only prepregs and fiberglass scrim fabrics.
측정된 굴곡강성은 하기 표 1에 나타내었다.The measured flexural stiffness is shown in Table 1 below.
상기 실시예 및 비교예들에서 나타난 바와 같이 본 발명의 제조방법으로 제조된 낚싯대는 굴곡강성이 프리프레그만 사용한 경우에 비하여 87%, 프리프레그와 유리섬유 스크림 직물을 사용한 경우에 비하여 24% 향상됨을 알 수 있다. 이와 같이 본 발명은 기존의 제조공정을 유지하면서도 상기한 바와 같은 낚싯대 원주방향의 기계적 물성의 향상시킬 수 있는 신규, 유용한 발명인 것이다.As shown in the above Examples and Comparative Examples, the fishing rod manufactured by the manufacturing method of the present invention has an improved flexural rigidity of 87% compared to the case of using only prepreg and a 24% improvement compared to the case of using prepreg and glass fiber scrim fabric. Able to know. As described above, the present invention is a novel and useful invention that can improve the mechanical properties of the rod circumferential direction as described above while maintaining the existing manufacturing process.
