또한 본 발명은 상기 제조방법에 의해 제조되고, 내부에 다수의 볼트구멍(131)이 형성되고, 몸체 양면에 돌출부, 요철, 홈 중 하나이상이 다수 형성된 금속보강부재가 삽입되고, 외부는 카본파이버수지(130)로 형성되며, 볼트구멍(131)의 입구는 너트가 자리할 수 있도록 볼트구멍보다 큰 너트홈(145)이 형성되며, 너트홈(145) 하부로 금속보강부재(130)의 볼트구멍(131) 주위가 드러나도록 형성된 것을 특징으로 하는 카본파이버 휠에 관한 것이다. In addition, the present invention is manufactured by the manufacturing method, a plurality of bolt holes 131 is formed inside, a metal reinforcing member formed with a plurality of protrusions, irregularities, grooves on both sides of the body is inserted, the outside is carbon fiber It is formed of a resin 130, the inlet of the bolt hole 131 is formed with a nut groove 145 larger than the bolt hole so that the nut can be located, the bolt of the metal reinforcing member 130 under the nut groove 145 It relates to a carbon fiber wheel, characterized in that formed around the hole (131).

종래기술은 프리프레그(Prepreg), CFRP)를 사용하여 소재를 소정 모양으로 재단한 다음, 소정의 두께로 적층시켜 진공, 압공에 의해 압축 경화시키는 방법은 100% 카본파이버 휠이 가능하고 휠의 구조적 강도는 크게 강화시킬 수는 있으나, 재단, 적층 등의 공정으로 인하여 휠 모양을 스마트하게 형성하기 어렵고 투박하게 형성될 수밖에 없을 뿐 아니라 이와 같은 공정절차로 생산성이 저하되고 또한 이로 인한 원가상승 등 비용증가의 문제점이 있는 것이다.In the prior art, a method of cutting a material into a predetermined shape using prepreg and CFRP, then laminating it to a predetermined thickness and compressing and curing by vacuum or pressure can be 100% carbon fiber wheel, and the structure of the wheel Strength can be greatly strengthened, but it is difficult to form wheels smartly and clutterly due to cutting and lamination processes. There is a problem.

본 발명은 가볍고 강도가 큰 카본파이버를 사용하여 생산성이 높은 카본파이버 휠의 제조방법 및 그 제조방법에 의해 제조된 카본파이버 휠을 제공하기 위한 것이다.The present invention is to provide a carbon fiber wheel produced by the production method and a carbon fiber wheel produced by the production method of high productivity using light and high strength carbon fiber.

본 발명은 카본파이버를 조각으로 분쇄한 다음 수지와 혼합한 카본파이버수지 혼합액을 만들고, 이 혼합액으로는 사출에 의해 카본파이버 휠을 생산하는 방법이다. The present invention is a method of producing a carbon fiber resin mixture by pulverizing the carbon fiber into pieces and then mixed with a resin, and producing the carbon fiber wheel by injection into the mixture.

자동차는 수톤 이상의 하중력이 타이어에 작용하고, 타이어를 살펴보면 차량몸체와 연결된 브레이크에는 타이어를 고정하는 다수의 볼트가 형성되어 있으며, 브레이크디스크의 볼트가 타이어 휠에 삽입되어 너트체결되며, 따라서 차량에서 타이어에 걸리는 하중력은 결국 차량과 타이어를 연결하는 휠의 볼트체결부분인 것이다.In the case of a car, a load force of several tons or more acts on the tire, and when looking at the tire, a number of bolts for fixing the tire are formed on the brake connected to the vehicle body, and the bolt of the brake disc is inserted into the tire wheel to be nut-connected, thus The load on the tire is, after all, the bolted portion of the wheel connecting the vehicle to the tire.

이러한 관계로 인하여 카본파이버수지를 사출로 휠을 제조하였을 때 시험결과 힘이 집중되는 휠의 볼트체결부분 응력이 집중되어 파손의 위험이 높은 것을 알 수 있었으며, 이를 해결하기 위하여 본 발명은 다수개의 볼트구멍이 형성된 금속보강부재를 넣어서 인서트사출에 의해 카본파이버 휠을 제조하는 방법을 택한 것이다.Due to this relationship, when the wheel was manufactured by injection of carbon fiber resin, it was found that the stress of the bolted portion of the wheel where the force is concentrated is concentrated and the risk of breakage is high. A method of manufacturing a carbon fiber wheel by insert injection by inserting a metal reinforcing member having a hole is selected.

그러나 금속은 카본파이버와 재질이 다르기 때문에 차량의 큰 하중을 받게 되면 금속보강부재와 카본파이버수지 사이가 분리되고 유동성이 발생하여 시간이 지나면서 파손될 수 있는 가능성이 있었으며, 이를 해결하기 위하여 본 발명은 삽입되는 금속보강부재의 양쪽 표면에 요철, 돌출부, 홈 중 하나 이상의 형태를 다수 형성함으로써 금속보강부재와 카본파이버수지 간 접착력을 크게 증강시킬 수 있었으며, 큰 하중이 작용하면 요철, 돌출부는 하중을 분산시켜 금속보강부재와 카본파이버수지 간 국부적 힘의 집중을 분산시키도록 형성한 것이다.However, since the metal is different from the carbon fiber, when the vehicle is subjected to a large load, there is a possibility that the metal reinforcing member and the carbon fiber resin are separated and fluidity may be damaged over time. By forming one or more of irregularities, protrusions and grooves on both surfaces of the metal reinforcing member to be inserted, the adhesion between the metal reinforcing member and the carbon fiber resin can be greatly increased. It is formed to disperse local concentration of force between the metal reinforcing member and the carbon fiber resin.

이와 같은 본 발명의 요철 등이 형성된 금속보강부재를 넣어 인서트 사출에 의해 차량의 큰 하중이 작용하는 타이어에 충분한 강도의 휠을 제공할 수 있게 된 것이며, 인서트 사출방법으로 인하여 생산성 향상에 크게 기여하는 것이다.By inserting the metal reinforcing member formed with such irregularities of the present invention, it is possible to provide a wheel of sufficient strength to a tire to which a large load of the vehicle is applied by insert injection, which greatly contributes to productivity improvement due to the insert injection method. will be.

금속보강부재의 금속종류는 강관, 알류미늄 등 다양한 금속을 사용할 수 있다.As the metal type of the metal reinforcing member, various metals such as steel pipe and aluminum can be used.

카본파이버를 합침하는 수지 또한 통상 알려진 다양한 경화성, 가소성 수지에서 선택하여 사용할 수 있고 첨가제를 첨가할 수 있으며, 이와 같은 수지, 카본파이브 분쇄 등은 종래 선행기술에 널리 알려진 공개기술 또는 통상기술로서 이에 대한 구체적인 기술은 생략함.Resin impregnating carbon fibers may also be selected from a variety of commonly known curable and plastic resins and may be added with additives. Such resins, carbon fiber pulverization, and the like are widely known in the art, or as a conventional technique. The detailed description is omitted.

본 발명은 휠에서 차량 하중이 집중되는 휠의 볼트구멍부분을 보강하기 위하여 다수의 볼트구멍이 형성되고, 카본파이버와 접착력을 강화시키고 구조적 강도를 증강시키기 위하여 표면에 다수의 요철 등을 형성한 금속보강부재를 삽입하여 인서트사출에 의해 카본파이버 휠을 제조함으로써 휠 강도를 현저하게 증강시키는 효과가 있으며, 차량의 하중을 충분히 감당할 수 있는 카본파이버 휠을 인서트사출에 의해 제조 가능토록 함으로써 종래 진공, 압공에 의한 카본파이버 휠 제조방법에 비해 생산성을 현저하게 향상시키는 효과가 있다.In the present invention, a plurality of bolt holes are formed to reinforce the bolt hole portion of the wheel in which the vehicle load is concentrated on the wheel, and a metal having a plurality of irregularities or the like formed on the surface in order to reinforce adhesive strength with carbon fiber and to enhance structural strength. By inserting a reinforcing member to produce a carbon fiber wheel by insert injection, it is effective to reinforce wheel strength remarkably. By insert inserting a carbon fiber wheel that can adequately bear the load of a vehicle, it is possible to manufacture a carbon fiber wheel by insert injection. Compared with the carbon fiber wheel manufacturing method, there is an effect of significantly improving the productivity.

도 1은 본 발명의 일 실시예로서의 금속보강부재(130)를 부분적인 단면을 보여주는 것이며, 도 4는 기존의 금속 휠에서 본 발명의 금속보강부재(130)의 위치와 모양을 보여주는 것으로, 금속보강부재(130)에는 브레이크디스크에서 나온 볼트(도 3 참조)가 삽입되는 다수의 볼트구멍(131)이 형성되어 있으며 볼트구멍 부분을 제외하면 모든 금속보강부재(130) 부분은 카본섬유수지(140) 내부에 위치되도록 인서트사출된 것이다.Figure 1 shows a partial cross-section of the metal reinforcing member 130 as an embodiment of the present invention, Figure 4 shows the position and shape of the metal reinforcing member 130 of the present invention in a conventional metal wheel, metal reinforcement The member 130 is formed with a plurality of bolt holes 131 into which the bolts (see FIG. 3) from the brake disc are inserted. All of the metal reinforcing members 130 except for the bolt holes are formed of the carbon fiber resin 140. The insert is ejected to be located inside.

본 발명의 카본파이버 휠의 볼트구멍(131)에 삽입된 볼트(111)에 너트(152)을 체결하면 너트의 일부 또는 전부가 너트홈(154)에 들어간 상태가 되며, 너트 하부는 금속보강부재(130)에 접하도록 체결된다.When the nut 152 is fastened to the bolt 111 inserted into the bolt hole 131 of the carbon fiber wheel of the present invention, a part or all of the nut enters the nut groove 154, and the bottom of the nut is a metal reinforcing member. It is fastened to contact 130.

도 2는 차량 하중력이 작용할 때 발생하는 힘분산선(165)를 도시한 것으로, 예를 들어 움직이는 차량이 화살표 방향으로 하중력(165)이 금속보강부재(130)에 각 돌출부(133)의 끝에서 시작한 힘분산선(165)이 카본파이버수지(140) 속으로 경사진 선을 따라 분산되는 것이다.FIG. 2 illustrates a force distribution line 165 generated when a vehicle load force is applied. For example, a load force 165 is applied to the metal reinforcement member 130 in the direction of an arrow of a moving vehicle. The force dispersing line 165 starting from the end is dispersed along the inclined line into the carbon fiber resin 140.

이와 같이 돌출부(133)은 힘이 집중되어 분산되는 힘분산선(165)을 각기 형성하여 힘을 분산시켜 줌으로써 금속보강부재(130)와 카본파이버수지(140) 간 국부적으로 힘이 집중되는 것을 완화시켜 휠의 구조적 강도 증강에 크게 기여하는 것이다.As described above, the protrusion 133 reduces the localized concentration of force between the metal reinforcing member 130 and the carbon fiber resin 140 by dispersing the force by forming a force distribution line 165 each of which the force is concentrated. This greatly contributes to the structural strength of the wheel.
