자동차 내장재에 적용 가능한 PET 복합 기재 성형층 최적화 및 연구 Study on PET composite layer optimization to automobile interior material |
| 초록 |
PET is a good candidate for automobile interior materials because of its excellent physical properties such as heat resistance, lightweight and high mechanical strength. In automobile, it is mainly applied a headliner which is used on ceiling part to absorb and insulate external noise and heat. Natural fiber, PU, PP-GF are commonly used on this headliner parts. Among them, PP-GF reinforced board that is mixed PP on reinforced glass fiber shows high mechanical strength and lightweight. However, PP-GF has some problems like post-deformation after their forming and scattering interior matters when it exposed on Curtain Air Bag test. In this study, we formed PET to uniform cell distribution and made a sheet board through extrusion molding process. We studied their optimum layer composition by stacking samples with various density and thickness. And we also characterized their mechanical strength and thermal properties by Mechanical properties, TGA and DSC. |
