이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 자동차 도어 내측 외주면에 일체로 몰딩 성형되는 웨더스트립의 개략 구조도이고, 도 3은 본 발명의 자동차 웨더스트립 일체형 도어 제작방법을 설명하기 위한 금형 내부를 나타낸 개략 구조도로서, 폴리프로필렌 60 ~ 70 중량% 및 장섬유(Long Glass Fiber) 30 ~ 40 중량%가 함유된 혼합물을 혼합 및 용융시켜 자동차 도어(110)를 제작한다.FIG. 2 is a schematic structural view of a weather strip integrally molded on the inner circumferential surface of an automobile door according to the present invention. FIG. 3 is a schematic structural view showing the interior of a mold for explaining a method for manufacturing an automotive weather strip- 60 to 70% by weight and long fiber (30 to 40% by weight) are mixed and melted to manufacture the automobile door 110.

상기 도어 인너패널을 구성하는 매트리스 형태의 폴리에틸렌 기지재료에 장섬유(Long Glass Fiber)의 함유량이 40 중량% 이상 혼합될 경우, 충돌에 따른 충격강도가 우수한 반면에, 오히려 상기 장섬유의 조직을 응집시켜 응력을 전달하는 과정 및 상기 장섬유 조직을 보호하는 구조적인 형태를 이루기 위하여, 상기 장섬유의 함유량을 40 중량% 이하로 제한할 필요가 있으며, 또한 상기 장섬유의 함유량이 30 중량% 이하일 경우에는, 이와 반대로 충돌에 따른 충격강도가 오히려 극히 취약하는데 기인하는 것으로, 상기 장섬유가 기지재료인 폴리프로필렌에 대하여 30 ~ 40 중량%인 것이 바람직하다.When the content of the long glass fiber is mixed in a content of 40% by weight or more in a mattress-like polyethylene matrix constituting the door inner panel, the impact strength due to the impact is excellent. On the other hand, It is necessary to limit the content of the long fibers to 40% by weight or less in order to form a structural form for protecting the long fiber structure. When the content of the long fibers is 30% by weight or less On the contrary, the impact strength due to the collision is extremely weak, and it is preferable that the long fiber is 30 to 40% by weight based on polypropylene as a matrix material.
