Crash PAD 표피재의 열노화에 따른 특성변화 연구

Crash pad for automotive interior is composed of substrate, foam pad, and surface skin. Therefore, physical properties of crash pad are dependent on those components. However, chemical and thermal properties of material such as mechanical strength, elongation, and brittleness in low temperature are deteriorated along with heat and light exposure in certain period of time. In this study, physical and chemical properties of heat aged crash pad surface material have been investigated.
