화살대는 한번 부러지면 다수의 카본 파이버가 일방향으로 나란히 배열되어 있는 카본 파이버 시트의 결따라 쪼개어 지므로 쪼개진 부분이 날카로워 인체에 해를 끼치기 쉽다.When the shaft is broken, a plurality of carbon fibers are split along the direction of the carbon fiber sheet arranged in one direction, so that the split portion is sharp, which is likely to cause harm to the human body.

또한, 화살대의 경도가 단단하지 않아 쉽게 쪼개어진다는 단점이 있다.In addition, there is a disadvantage in that the hardness of the shaft is not rigid and is easily broken.

본 발명은 전술한 문제점을 해결하기 위하여 안출된 것으로, 부러지더라도 날카로운 면이 노출되지 않아 안전하며, 경도가 커지기 때문에 단단하고 잘 쪼개지지 않으며, 부드럽고 매끄러운 표면을 유지할 수 있고, 화살대의 외관을 환경친화적으로 장식할 수 있으며, 화살대의 위장이 가능하고, 화살대의 생산단가를 낮출 수 있어 경제적이며, 화살대의 쪼개짐이 적을 뿐만 아니라, 힘을 많이 받는 부분인 끝단을 보호하여 화살대의 쪼개어짐을 방지하고 강도를 보강할 수 있는 화살대를 제공하는 데 그 목적이 있다.The present invention has been conceived in order to solve the above-mentioned problems, and it is an object of the present invention to solve the above-mentioned problems, and it is an object of the present invention to provide a shaft It is economical because it can decorate friendly, it can camouflage the shaft, lower the production cost of the shaft and it is economical. In addition to the small splitting of the shaft, it also protects the end which is the part that receives much force, Which is capable of reinforcing the shaft.

전술한 목적을 달성하기 위한 본 발명의 화살대는, 일방향으로 나란히 배열 된 다수의 카본 파이버에 열경화성 수지가 도포된 후 가열 경화되어 구성된 카본 파이버 시트가 다수개 적층되되, 상기 다수의 카본 파이버 시트는 카본 파이버 시트에 포함된 카본 파이버의 배열이 서로 교차하도록 적층되어 있고, 상기 다수의 적층된 카본 파이버 시트의 최외면 일측에는 교차로 직조된 카본글래스 파이버 시트가 부착되고, 상기 다수의 적층된 카본 파이버 시트의 최외면 타측에는 비탄성 시트가 부착되는 것을 특징으로 한다.In order to accomplish the above object, the shaft of the present invention is characterized in that a plurality of carbon fiber sheets formed by applying a thermosetting resin to a plurality of carbon fibers arranged in one direction and curing by heating are laminated, Wherein a plurality of stacked carbon fiber sheets are laminated so that the arrangement of carbon fibers contained in the fiber sheet cross each other, and a cross-linked carbon fiber fiber sheet is attached to one outermost surface of the plurality of stacked carbon fiber sheets, And an inelastic sheet is attached to the other side of the outermost surface.

상기에 있어서, 상기 비탄성 시트는 천연섬유 또는 화학섬유로 구성되어, 다양한 무늬가 나염처리 되는 것이 바람직하다.In the above, the non-elastic sheet is preferably made of natural fibers or chemical fibers, and is preferably subjected to various patterns.

상기에 있어서, 상기 카본글래스 파이버 시트 외면의 일단에는 보호링이 끼워지는 것이 바람직하다.In the above, it is preferable that a protective ring is fitted to one end of the outer surface of the carbon fiber fiber sheet.

이하, 본 발명의 바람직한 일실시예를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명의 바람직한 실시예에 따른 화살대를 도시한 사시도이고, 도 2는 도 1의 내부 구조를 보이기 위한 단면도이며, 도 3은 도 1의 내부 구조를 보이기 위한 일부 단면도이고, 도 4의 a,b는 도 1의 카본글래스 파이버 시트를 도시한 평면도이다.FIG. 1 is a perspective view showing a shaft according to a preferred embodiment of the present invention, FIG. 2 is a cross-sectional view showing the internal structure of FIG. 1, FIG. 3 is a partial cross-sectional view showing an internal structure of FIG. 1, and a and b are plan views showing the carbon glass fiber sheet of Fig.

도 1 내지 도 3에 도시한 바와 같이, 화살대(100)는 내부가 빈 파이프 형상이며, 다수개의 카본 파이버 시트(10)가 적층되어 있고, 적층된 카본 파이버 시트(10)의 최외면(10a)의 일측에는 카본글래스 파이버 시트(20)가 부착되고, 적층된 카본 파이버 시트(10)의 최외면(10a)의 타측에는 비탄성 시트(60)가 부착되어 있다.1 to 3, the shaft block 100 has an inner hollow pipe shape, and a plurality of carbon fiber sheets 10 are laminated. The outermost surface 10a of the laminated carbon fiber sheet 10 A carbon fiber glass sheet 20 is attached to one side of the carbon fiber sheet 10 and an inelastic sheet 60 is attached to the other side of the outermost surface 10a of the laminated carbon fiber sheet 10.

카본 파이버 시트(10)는 일방향으로 나란히 배열된 다수의 카본 파이버에 열경화성 수지(thermosetting resin)가 도포된 후 가열 경화되어 구성된다.The carbon fiber sheet 10 is formed by applying a thermosetting resin to a plurality of carbon fibers arranged side by side in one direction, followed by heating and curing.

열경화성 수지는 불용성이고 열에 의해 용해되지 않으며, 페놀 수지, 푸란 수지, 아미노플라스틱, 불포화산의 폴리에스테르 수지와 알키드 수지, 에폭시 수지, 폴리우레탄, 실리콘 등이 있다.The thermosetting resin is insoluble and does not dissolve by heat, and includes phenol resin, furan resin, amino plastic, polyester resin of unsaturated acid and alkyd resin, epoxy resin, polyurethane, silicone and the like.

다수의 적층된 카본 파이버 시트(10)는 카본 파이버 시트(10)에 포함된 카본 파이버의 배열이 서로 교차하도록 적층되어 있다.The plurality of stacked carbon fiber sheets 10 are laminated such that the arrangement of the carbon fibers contained in the carbon fiber sheet 10 cross each other.

이렇게 카본 파이버의 배열이 서로 교차하도록 적층되어 있어, 부러지더라도 날카로운 면이 노출되지 않아 안전하다.Thus, the carbon fibers are stacked so as to intersect with each other, so that even if broken, the sharp surface is not exposed and is safe.

본 명세서의 도면에서는 카본 파이버 시트(10)가 5개의 층으로 적층되어 있는 것으로 도시하였지만 이는 일실시예에 불과하며, 실시예에 따라 달라질 수 있음은 물론이다.In the drawings of the present specification, the carbon fiber sheet 10 is illustrated as being laminated in five layers, but this is merely an example, and it goes without saying that it may vary depending on the embodiment.

카본글래스 파이버 시트(20)는 다수의 적층된 카본 파이버 시트(10)의 최외면(10a)의 일측에 부착되며, 카본글래스 파이버 시트(20)는, 도 4의 a,b에 도시한 바와 같이, 카본 파이버와 글래스 파이버가 교차로 직조되어 있다.The carbon fiber fiber sheet 20 is attached to one side of the outermost surface 10a of the plurality of laminated carbon fiber sheets 10 and the carbon fiber fiber sheet 20 , And carbon fibers and glass fibers are woven at an intersection.

상기와 같이, 카본 파이버 시트(10)의 외측면의 일측에 교차로 직조된 카본글래스 파이버 시트(20)가 부착됨으로써, 경도가 커지기 때문에 단단하고 잘 쪼개지지 않으며, 부드럽고 매끄러운 표면을 유지할 수 있다.As described above, since the carbon fiber fiber sheet 20 woven with the cross weaving is attached to one side of the outer surface of the carbon fiber sheet 10, the hardness is increased, so that the carbon fiber sheet 20 can be hard and not splittable and can maintain a smooth and smooth surface.

비탄성 시트(60)는 다수의 적층된 카본 파이버 시트(10)의 최외면(10a)의 타측에 부착된다.The inelastic sheet 60 is attached to the other side of the outermost surface 10a of the plurality of laminated carbon fiber sheets 10. [

비탄성 시트(60)는 섬유조직화된 소재를 말하며, 천연섬유 또는 화학섬유로 구성되어, 다양한 무늬가 나염처리 되는 것이 바람직하다.The inelastic sheet 60 refers to a fiber-structured material, and is preferably composed of natural fibers or chemical fibers, and is subjected to various patterns of knitting.

천연섬유는 면,마,양모,견,석면 등의 자연적인 현상에서 발생되는 매체로 부터 섬유를 얻는 것이다.Natural fibers are fibers obtained from natural sources such as cotton, hemp, wool, silk, and asbestos.

인조섬유는 자연적인 방법으로는 그 생산량의 한계와 가격, 물성 등 여러 문제점을 극복하기 위하여 나일론, 폴리에스테르, 아세테이트레이온, 비스코스레이온 등, 인간이 화학적인 방법으로 섬유를 얻는 것을 말한다.Artificial fiber is a natural way of obtaining fibers by human chemical methods such as nylon, polyester, acetate rayon, viscose rayon, etc. in order to overcome various problems such as limit of production, price and physical properties.

이렇게, 카본 파이버 시트(10)의 외측면의 타측에 다양한 무늬가 나염처리된 비탄성 시트(60)가 부착됨으로써, 화살대(100)의 외관을 환경친화적으로 장식할 수 있으며, 화살대(100)의 위장이 가능하다. 또한, 비탄성 시트(60)는 가격이 저렴하므로 화살대(100)의 생산단가를 낮출 수 있어 경제적이며, 화살대(100)의 쪼개짐이 적다.In this manner, the inelastic sheet 60 with various patterns is attached to the other side of the outer surface of the carbon fiber sheet 10, so that the appearance of the shaft 100 can be decorated environmentally, This is possible. In addition, since the inelastic sheet 60 is inexpensive, the manufacturing cost of the shaft 100 can be reduced, which is economical, and the shaft 100 is less split.

한편, 보호링(30)은 카본글래스 파이버 시트(20) 외면의 일단에 끼워져, 힘을 많이 받는 부분인 끝단을 보호하므로 화살대(100)의 쪼개어짐을 방지하고 강도를 보강할 수 있다.On the other hand, the protection ring 30 is fitted to one end of the outer surface of the carbon fiber fiber sheet 20, and protects the tip, which is a part that receives a lot of force, so that the shaft 100 can be prevented from being split and the strength can be reinforced.

보호링(30)이 끼워진 화살대(100)의 일측에는 오뉘(40)가 끼워져 화살대(100)의 일측이 폐쇄되며, 화살대(100)의 최외면 즉, 카본글래스 파이버 시트(20) 외면에는 다수의 깃(50)이 고정된다.A shaft 40 is inserted into one side of the shaft 100 on which the protection ring 30 is inserted so that one side of the shaft 100 is closed and an outermost surface of the shaft 100, The collar 50 is fixed.

화살대(100)의 타측에는 본 명세서의 도면상에서는 도시하지 않았지만, 화살촉이 끼워져 폐쇄된다.The other side of the shaft 100 is not shown in the drawings of the present specification, but an arrowhead is inserted and closed.
