Abstract

본 논문에서는 범퍼 스키드 플레이트 및 아웃사이드미러 하우징 부품에 적용되는 polypropylene (PP)와 acrylonitrile styrene acrylate (ASA) 소재를 활용하여 무도장 메탈릭 소재 구현에 대해 연구하였다. 금속 효과를 극대화하기 위해 알루미늄 입자의 종류, 크기, 함량을 최적화하였고 웰드 라인을 은폐하기 위해 종횡비가 상이한 하이브리드 알루미늄 입자를 사용하였다. 또한 부품 표면에 발생되는 플로우 마크를 개선하기 위해 유동성을 제어하였으며 사출 해석을 수 행하였다.

In this paper, paint-free metallic plastic material, polypropylene (PP) and acrylonitrile styrene acrylate (ASA) materials were investigated on the applications for bumper skid plate and outside mirror housing parts. In order to maximize metallic effect, type, size and content of aluminum pigment were optimized based on flop index. Hybrid aluminum pigments with different aspect ratios were used to conceal weld lines. By controlling the fluidity of the material, the flow mark problem, generated on the surface of the part, was resolved. We also investigated the surface defects of flow and weld lines by using the developed modeling and simulation.
