도 4는 본 발명에 따른 고강성 열가소성 보강재의 다른 예를 나타내는 단면도이다.4 is a cross-sectional view showing another example of a high rigid thermoplastic reinforcing material according to the present invention.

본 발명은 고강성 열가소성 복합재에 관한 것이다.The present invention relates to a high rigid thermoplastic composite.

최근 자동차 산업에서는 차량의 중량 증가에 따라 경량화 및 요구 특성이 높아지면서 사용 소재의 강도 및 강성 향상이 크게 요구되고 있다. 이러한 추세에서, 열가소성 복합재료는 높은 비강성으로 인하여 적용이 증가하고 있어 GMT(유리섬유 매트 열가소성 복합재), LFT(장섬유강화 복합재) 등의 소재의 적용이 증가하고 있다.Recently, in the automobile industry, as the weight of a vehicle increases, the weight and demand characteristics thereof increase, and thus, the strength and rigidity of the material used are greatly increased. In this trend, the application of thermoplastic composite materials is increasing due to the high specific rigidity, and the application of materials such as GMT (glass fiber mat thermoplastic composite) and LFT (long fiber reinforced composite) is increasing.

그러나, 이들 소재는 유동성을 이용한 프레스 성형법을 사용해야 하는 제약이 있기 때문에, GMT는 유동성이 가능한 부직(non-woven) 형태의 유리섬유매트를 사용하고, LFT는 촙드(chopped) 유리섬유를 사용하므로 특성을 향상시키는데 한계가 있다. However, since these materials have limitations in using a press molding method using fluidity, GMT uses a non-woven glass fiber mat capable of fluidity, and LFT uses chopped glass fiber. There is a limit to improve.

이를 해결하기 위해, 성형시 별도의 보강재를 삽입하는 방법이 적용되고 있으나, 보강재 적층 및 유동성의 어려움뿐만 아니라 박리 현상 등의 문제가 있어 적용에 한계가 있다.In order to solve this problem, a method of inserting a separate reinforcement during molding has been applied, but there are limitations in application due to problems such as peeling phenomenon as well as difficulty in laminating reinforcement and fluidity.

따라서, 본 발명의 목적은 유동성을 갖는 고강성 열가소성 복합재를 제조하여 제품 강도와 강성을 높이는 동시에 성형시 박리 현상을 없애는 것이다.Accordingly, an object of the present invention is to manufacture a highly rigid thermoplastic composite having fluidity, to improve product strength and rigidity and to eliminate peeling during molding.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

도 1은 본 발명의 일 실시예에 따른 고강성 열가소성 보강재를 적용한 제품의 단면도이다.1 is a cross-sectional view of a product to which a high rigidity thermoplastic reinforcement is applied according to an embodiment of the present invention.

도 1을 참조하면, 상하로 적층되는 두 GMT 소재(100, 300) 사이에는 본 발명 에 따른 고강성 열가소성 보강재가 삽입되고, 가령 프레스 공정으로 성형된다.Referring to FIG. 1, a high rigid thermoplastic reinforcement according to the present invention is inserted between two GMT materials 100 and 300 stacked up and down, and is molded by, for example, a pressing process.

도 2는 본 발명에 따른 고강성 열가소성 보강재의 일 예를 나타내는 단면도이다.2 is a cross-sectional view showing an example of a highly rigid thermoplastic reinforcing material according to the present invention.

도 2를 참조하면, 유리섬유 직조물이나 폴리에스테르 직조물, 유리섬유와 폴리프로필렌의 혼합 직조물, 또는 카본파이버 등의 직조(woven) 보강부재(220)의 표면과 이면에 각각 열가소성 수지 또는 열가소성 수지와 유리섬유로 이루어진 열가소성 복합재(210, 230)가 함침된다.Referring to FIG. 2, thermoplastic resins or thermoplastic resins and glass are respectively formed on the front and back surfaces of woven reinforcing members 220 such as glass fiber woven or polyester woven, mixed woven fiber and polypropylene, or carbon fiber. The thermoplastic composites 210 and 230 made of fibers are impregnated.

이와 같이 구성된 고강성 열가소성 보강재(200)를 개재하여 상하에 GMT 소재(100, 200)를 위치한 후 성형 가공하면, 고강성 열가소성 보강재(200)의 외부층을 구성하는 열가소성 복합재(210, 230)가 GMT 소재(100, 300)와의 결합력을 증가시켜 박리 현상을 방지한다. 다시 말해, 열가소성 복합재(210, 230)가 직조된 보강부재(220)의 내부로 함침되어 보강부재(200)와 결합하고, 이와 동시에 열가소성 복합재(210, 230)는 열가소성 수지나 유리섬유가 함유된 열가소성 수지로 구성되므로 열가소성인 GMT 소재(100, 300)와는 단단하게 결합이 이루어지므로 전체적으로 보강재(200)와 GMT 소재(100, 300)가 단단하게 결합한다.When the GMT materials 100 and 200 are positioned above and below the high stiffness thermoplastic reinforcement 200 configured as described above and then molded, the thermoplastic composites 210 and 230 constituting the outer layer of the high stiffness thermoplastic reinforcement 200 are formed. The peeling phenomenon is prevented by increasing the bonding force with the GMT materials 100 and 300. In other words, the thermoplastic composites 210 and 230 are impregnated into the woven reinforcing member 220 to be combined with the reinforcing member 200, and at the same time, the thermoplastic composites 210 and 230 contain thermoplastic resin or glass fiber. Since it is made of a thermoplastic resin and is firmly bonded to the thermoplastic GMT materials 100 and 300, the reinforcement 200 and the GMT materials 100 and 300 are tightly coupled as a whole.

바람직하게, 열가소성 수지로는 폴리프로필렌이 적용될 수 있다.Preferably, polypropylene may be applied as the thermoplastic resin.

도 1의 실시예와 달리 고강성 열가소성 보강재(200)는 GMT 소재(100, 300)에 대해 일면만 접합할 수 있다. 도 3은 본 발명의 다른 고강성 열가소성 보강재를 적용한 제품을 나타내는 실시예이다.Unlike the embodiment of FIG. 1, the high stiffness thermoplastic reinforcement 200 may be bonded to only one surface of the GMT materials 100 and 300. Figure 3 is an embodiment showing a product to which another high rigidity thermoplastic reinforcement of the present invention is applied.

도 3을 참조하면, 다수의 적층된 GMT 소재(100. 110, 120) 중 최하부에 위치 한 GMT 소재(120)의 이면에 본 발명의 고강성 열가소성 보강재(200')가 접합한다.Referring to FIG. 3, the highly rigid thermoplastic reinforcement 200 ′ of the present invention is bonded to the rear surface of the GMT material 120 positioned at the bottom of the plurality of laminated GMT materials 100. 110 and 120.

도 4는 본 발명에 따른 고강성 열가소성 보강재의 다른 예를 나타내는 단면도이다.4 is a cross-sectional view showing another example of a high rigid thermoplastic reinforcing material according to the present invention.

도 4를 참조하면, 직조(woven) 보강부재(220)의 표면, 즉 GMT 소재(120)와 대향하는 면에 열가소성 수지 또는 유리섬유를 함유한 열가소성 수지로 이루어진 열가소성 복합재(230)가 함침된다.Referring to FIG. 4, a thermoplastic composite material 230 made of a thermoplastic resin containing a thermoplastic resin or glass fiber is impregnated on a surface of the woven reinforcing member 220, that is, a surface facing the GMT material 120.

이와 같이, 본 발명의 보강부재는 GMT 소재와의 결합을 위해 결합면에만 열가소성 복합재를 함침해도 무방하다.As such, the reinforcing member of the present invention may be impregnated with a thermoplastic composite only on the bonding surface for bonding with the GMT material.

[표 1]은 본 발명에 따른 고강성 열가소성 보강재와 종래의 보강재의 물성을 비교한 결과를 나타낸다.Table 1 shows the results of comparing the properties of the high stiffness thermoplastic reinforcing material according to the present invention and the conventional reinforcing material.
