도 1은 본 발명의 일실시예에 따른 원단 일체형 차량용 시트백 프레임의 재료인 원단 일체형 복합소재를 개략적으로 도시한 구성도이다.BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a schematic view showing a fabric-integrated composite material as a material for a seat back frame for a one-body integrated vehicle according to an embodiment of the present invention.
도시한 바와 같이, 원단 일체형 복합소재(100)는 원단(110)과 열가소성 섬유강화복합소재(120)를 포함한다.As shown in the figure, the fabric-integrated composite material 100 includes a fabric 110 and a thermoplastic fiber-reinforced composite material 120.
보다 구체적으로, 원단(110)은 PET 부직포를 포함하여 이루어질 수 있다. More specifically, the fabric 110 may comprise a PET nonwoven fabric.
또한, 원단(110)에는 외부에서 가해지는 열에 의해 원단의 패턴이 변형되지 않도록 실리콘 코팅층(111)이 형성될 수 있다. In addition, the silicone coating layer 111 may be formed on the fabric 110 so that the pattern of the fabric is not deformed by heat applied from the outside.
또한, 실리콘 코팅층(111)은 패턴보호기능을 확보하기 위해 0.2mm 내지 2mm 두께로 형성될 수 있다.In addition, the silicon coating layer 111 may be formed to have a thickness of 0.2 mm to 2 mm in order to secure a pattern-protecting function.
그리고 열가소성 섬유강화복합소재(120)는 실리콘 코팅층(111)이 형성되지 않은 원단(110)의 일측면에 결합되고, 연속섬유 강화 열가소성수지(CFT: Continuous Fiber reinforced Thermoplastic) 또는 연속섬유 강화 열가소성수지(CFT )를 포함하는 복합수지로 이루어질 수 있다.The thermoplastic fiber reinforced composite material 120 is bonded to one side of the fabric 110 on which the silicone coating layer 111 is not formed and is made of a continuous fiber reinforced thermoplastic (CFT) or a continuous fiber reinforced thermoplastic resin CFT). ≪ / RTI >
또한, 연속섬유 강화 열가소성수지(CFT)에 포함된 열가소성 수지는 폴리프로필렌 수지, 폴리에틸렌 수지, 폴리아미드 수지, 폴리에스테르 수지, 폴리페닐렌설파이드 수지 및 이들의 조합으로 이루어진 군으로부터 선택된 적어도 하나를 포함할 수 있다. The thermoplastic resin contained in the continuous fiber-reinforced thermoplastic resin (CFT) may include at least one selected from the group consisting of a polypropylene resin, a polyethylene resin, a polyamide resin, a polyester resin, a polyphenylene sulfide resin, and a combination thereof .
그리고 연속섬유 강화 열가소성수지(CFT)는 폴리프로필렌 수지와 연속 유리섬유(GF: continuous glass fiber)로 이루어질 수 있다. The continuous fiber reinforced thermoplastic resin (CFT) can be made of polypropylene resin and continuous glass fiber (GF).
그리고 연속섬유 강화 열가소성수지(CFT)는 외부충격을 효과적으로 흡수하고, 강성 및 충격 강도가 높아 차량용 시트백 프레임으로 매우 적합하다. The continuous fiber reinforced thermoplastic resin (CFT) effectively absorbs external impact and is highly suitable for a vehicle seat back frame because of its high rigidity and impact strength.
그러나 연속섬유 강화 열가소성수지(CFT)를 이용하여 시트백 프레임을 성형할 경우 유리섬유가 노출되어 사용시 분진 및 따가움을 느낄 수 있고, 이를 방지하기 위해 도장 또는 원단 감싸기의 후공정이 요구된다.However, when a continuous frame-reinforced thermoplastic resin (CFT) is used to form a seat back frame, the glass fiber is exposed to dust and stains during use. To prevent this, post-processing of painting or fabric wrapping is required.
그러나 본 발명의 일실시예에 따른 원단 일체형 복합소재(100)는 원단(110)이 열가소성 섬유강화복합소재(120)의 일면을 커버하면서 일체로 형성됨에 따라 상기한 문제점이 미연에 방지된다.However, the fabric-integrated composite material 100 according to an embodiment of the present invention is formed integrally with the fabric 110 while covering one surface of the thermoplastic fiber-reinforced composite material 120, thereby preventing the above problem.
이에 대한 일예로서, 도 2는 도 1에 도시한 원단 일체형 복합소재를 이용한 일실시예에 따른 원단 일체형 차량용 시트백 프레임을 개략적으로 도시한 평면도이다. As an example, FIG. 2 is a plan view schematically showing a single-body integrated seat back frame for a vehicle according to an embodiment using the one-piece composite material shown in FIG.
도시한 바와 같이, 시트백 프레임(1000)는 원단부(1100)와 프레임부(1200)가 일체화된 원단 일체형 복합소재를 성형하여 이루어진다. As shown in the figure, the seat back frame 1000 is formed by molding a monolithic composite material in which the distal end portion 1100 and the frame portion 1200 are integrated.
또한 원단부(1100)는 PET 부직포를 포함하여 이루어지고, 프레임부(1200)는 연속섬유 강화 열가소성수지(CFT)로 이루어진다.Further, the distal end portion 1100 includes a PET nonwoven fabric, and the frame portion 1200 is made of a continuous fiber-reinforced thermoplastic resin (CFT).
그리고 원단 일체형 복합소재는 프레스에 의해 가압성형되어 도 2에 도시한 시트백 프레임(1000)이 형성된다.Then, the fabric-integrated composite material is press-formed by a press to form the seat back frame 1000 shown in Fig.
이하, 도 3 및 도 4를 참조하여 본 발명의 일실시예에 따른 원단 일체형 차량용 시트백 프레임을 제조하는 방법에 대하여 보다 자세히 기술한다.Hereinafter, with reference to FIGS. 3 and 4, a method of manufacturing a seat back frame for a one-body integrated type vehicle according to an embodiment of the present invention will be described in detail.
도 3은 본 발명의 일실시예에 따른 원단 일체형 차량용 시트백 프레임의 제조방법을 개략적으로 도시한 순서도이다.3 is a flowchart schematically showing a manufacturing method of a seat back frame for a one-body integrated vehicle according to an embodiment of the present invention.
도시한 바와 같이, 원단 일체형 차량용 시트백 프레임의 제조방법(S1000)은 원단 및 연속섬유 강화 열가소성수지 적층단계(S1100), 가열 및 가압 합지단계(S1200) 및 성형단계(S1300)를 포함한다. As shown in the figure, a manufacturing method (S1000) of a fabric-integrated vehicle seat back frame includes a fabric and a continuous fiber-reinforced thermoplastic resin lamination step (S1100), a heating and pressurizing step (S1200), and a molding step (S1300).
보다 구체적으로, 원단 및 열가소성 섬유강화 복합소재 적층단계(S1100)는 열가소성 섬유강화복합소재의 일면에 원단을 적층하여 원단 일체형 복합소재로 성형하기 위한 재료를 마련하기 위한 단계이다. More specifically, the fabric and thermoplastic fiber-reinforced composite material lamination step (S1100) is a step for preparing a material for forming a fabric-integrally composite material by laminating a fabric on one side of the thermoplastic fiber-reinforced composite material.
그리고, 열가소성 섬유강화복합소재는 연속섬유 강화 열가소성수지(CFT: Continuous Fiber reinforced Thermoplastic) 또는 연속섬유 강화 열가소성수지(CFT )를 포함하는 복합소재로 이루어질 수 있다. And, the thermoplastic fiber reinforced composite material can be made of a composite material including a continuous fiber reinforced thermoplastic (CFT) or a continuous fiber reinforced thermoplastic resin (CFT).
다음으로, 가열 및 가압 합지단계(S1200)는 적층된 원단과 연속섬유 강화 열가소성수지(CFT)에 열을 가하고, 가압하여 원단과 연속섬유 강화 열가소성수지(CFT)를 결합시켜 원단 일체형 복합소재를 형성하는 단계이다.Next, in the heating and pressurizing step (S1200), heat is applied to the laminated fabric and the continuous fiber-reinforced thermoplastic resin (CFT), and the press fabric is combined with the continuous fiber-reinforced thermoplastic resin (CFT) .
즉, 상기 원단에 대향된 연속섬유 강화 열가소성수지(CFT)의 일면은 열에 의해 용융된 상태가 되고, 원단은 연속섬유 강화 열가소성수지(CFT)의 일면에 가압되어 결합된다.That is, one side of the continuous fiber-reinforced thermoplastic resin (CFT) facing the fabric is melted by heat, and the fabric is pressed and bonded to one side of the continuous fiber-reinforced thermoplastic resin (CFT).
그리고 가열온도는 220°C ~ 240°C이고, 압력은 5~6Bar로 가해질 수 있다. The heating temperature is 220 ° C ~ 240 ° C and the pressure can be 5 ~ 6 Bar.
이때, 원단은 외부에서 가해지는 열에 의해 원단의 패턴이 변형되지 않도록 실리콘 코팅층이 형성된 원단이 채택될 수 있다.At this time, a fabric having a silicone coating layer may be adopted so that the pattern of the fabric is not deformed by the heat applied from the outside.
다음으로, 성형단계(S1300)은 가열 및 가압 합지단계(S1200)를 통해 원단과 연속섬유 강화 열가소성수지가 일체화된 원단 일체형 복합수지를 시트백 프레임 형상으로 성형하는 단계이다. Next, the molding step S1300 is a step of molding the monolithic composite resin in which the raw fabric and the continuous fiber-reinforced thermoplastic resin are integrated through the heating and pressing step (S1200) into a seatback frame shape.
이를 위해 성형단계(S1300)는 프레스 가압 성형단계로 이루어질 수 있다.For this, the forming step S1300 may be a press-pressing step.
그리고, 효율적인 성형을 위해 프레스 가압전에 원단 일체형 복합소재에 열을 가하는 예열단계를 포함한다. And a preheating step of applying heat to the fabric-integrated composite material before press-pressing for efficient molding.
그리고 예열단계에서 원단의 패턴이 변형되지 않도록 원단 측 보다 연속섬유 강화 열가소성수지 측에 높은 온도를 제공할 수 있다.And can provide a higher temperature on the continuous fiber-reinforced thermoplastic side than the far side so that the pattern of the fabric is not deformed during the pre-heating step.
그리고 프레스로 가압하여 차량용 시트백 프레임의 모양을 형성시킨다.And pressed by a press to form the shape of the vehicle seatback frame.
결국, 상기한 바와 같은 공정으로 구현될 경우, 원단 일체형 복합소재는 2번의 가열단계를 거치게 된다. 즉, 가열 및 가압 합지단계(S1200)에서 1차로 가열되고, 성형단계(S1300)에서 2차로 가열된다.As a result, when the process as described above is implemented, the composite material with a single fabric is subjected to two heating steps. That is, it is firstly heated in the heating and pressurizing step S1200, and then heated in the forming step S1300 secondarily.
따라서, 1차 가열단계인 가열 및 가압 합지단계(S1200)에서 합지효율을 향상시키기 위해 원단의 손상발생할 정도의 열을 가할 필요가 없고, 성형단계(S1300)를 통해 추가로 가열되고 가압됨에 따라 원단과 연속섬유 강화 열가소성수지는 완벽하게 일체화된다.Therefore, it is not necessary to apply heat to the fabric to damage the fabric in order to improve the laminating efficiency in the heating and pressurizing joining step (S1200), which is the first heating step, and further heating and pressing through the forming step (S1300) And the continuous fiber-reinforced thermoplastic resin are perfectly integrated.
도 4는 도 3에 도시한 성형단계의 일실시예를 개략적으로 도시한 세부공정도이다.Fig. 4 is a detailed process diagram schematically showing an embodiment of the molding step shown in Fig. 3. Fig.
도시한 바와 같이, 프레스 가압성형을 위해 원단 일체형 복합소재(100)를 상부금형(10)와 하부금형(20) 사이에 위치시킨다. 그리고 상부금형(10)을 하부로 이동시키고, 하부금형(20)을 상부로 이동시켜 원단 일체형 복합소재(100)를 가압 성형시킨다.As shown in the drawing, the fabric-integrated composite material 100 is press- Is positioned between the upper mold (10) and the lower mold (20). Then, the upper mold 10 is moved to the lower portion and the lower mold 20 is moved upward to press-mold the composite material 100 with one end.
그리고 프레스 가압성형 단계에서 원단 일체형 복합소재에 열을 가한 후 성형공정을 구현할 수 있고, 이때 원단(110) 측 보다 연속섬유 강화 복합수지(120) 측에 높은 온도를 제공하는 것이 바람직하다.In addition, it is preferable to provide a high temperature on the side of the continuous fiber-reinforced composite resin 120 rather than the side of the raw fabric 110 at the time of applying the heat to the fabric-integrated composite material in the press-pressing step.
또한, 원단 일체형 차량용 시트백 프레임은 추가공정인 사출성형에 의해 원단 일체형 차량용 시트백 프레임의 내측으로 보강재를 추가로 결합시킬 수 있다. Further, the full-body integrated vehicle seatback frame can further incorporate the reinforcing member into the inside of the fabric-integrated vehicle seatback frame by injection molding, which is an additional process.
즉, 도 5는 보강제가 성형된 원단 일체형 차량용 시트백 프레임의 일시예를 개략적으로 도시한 사시도이다. That is, Fig. 5 is a perspective view schematically showing a temporal example of a one-end integrated vehicle seatback frame formed with a reinforcing agent.
보다 구체적으로, 원단 일체형 차량용 시트백 프레임(2000)은 프레임 바디(2100) 및 보강제(2200)을 포함한다.More specifically, the fabric-integrated type vehicle seat back frame 2000 includes a frame body 2100 and a reinforcing agent 2200.
그리고 프레임 바디(2100)는 원단(2110)과 열가소성 섬유강화복합소재(2120)가 일체화되어 이루어진다.The frame body 2100 is formed by integrating the fabric 2110 and the thermoplastic fiber reinforced composite material 2120.
또한, 프레임 바디(2100)은 상기 열가소성 섬유강화 복합소재로 이루어지고, 연속섬유 강화 열가소성수지(CFT: Continuous Fiber reinforced Thermoplastic) 또는 연속섬유 강화 열가소성수지(CFT)를 포함하는 복합수지로 이루어질 수 있다.The frame body 2100 may be made of the thermoplastic fiber reinforced composite material and may be made of a composite resin including a continuous fiber reinforced thermoplastic (CFT) or a continuous fiber reinforced thermoplastic resin (CFT).
그리고 보강제(2200)는 프레임 바디(2100)의 내측인 열가소성 섬유강화복합소재에 사출성형된다.The reinforcing agent (2200) is injection molded into a thermoplastic fiber reinforced composite material inside the frame body (2100).
또한, 보강제(2200)는 프레임 바디(2100)에 강성과 강도를 제공하기 위한 것으로서, 장섬유 강화 열가소성 수지(LFT: Long Fiber reinforced Thermoplastic) 또는 단섬유강화 열가소성 수지(SFT) 또는 장섬유 강화 열가소성 수지(LFT)를 포함하는 소재로 이루어질 수 있다. The reinforcing agent 2200 is used to provide rigidity and strength to the frame body 2100. The reinforcing agent 2200 may be a long fiber reinforced thermoplastic (LFT) or a short fiber reinforced thermoplastic resin (SFT) or a long fiber reinforced thermoplastic resin (LFT).
그리고 보강제는 장섬유 강화 열가소성 수지(LFT)에 포함된 열가소성 수지는 폴리프로필렌 수지, 폴리에틸렌 수지, 폴리아미드 수지, 폴리에스테르 수지, 폴리페닐렌설파이드 수지 및 이들의 조합으로 이루어진 군으로부터 선택된 적어도 하나를 포함할 수 있다.The thermoplastic resin included in the long fiber reinforced thermoplastic resin (LFT) may include at least one selected from the group consisting of polypropylene resin, polyethylene resin, polyamide resin, polyester resin, polyphenylene sulfide resin, and combinations thereof can do.
이에 따라, 원단 일체형 차량용 시트백 프레임(2000)은 내측으로 보강제(2200)가 내재되고, 외측으로 원단(2110)이 결합된 상태가 된다.Accordingly, the seat back frame 2000 for a one-body integrated type vehicle has a reinforcing agent 2200 inside and a far end 2110 joined to the outside.
