PC 수지 사출성형품의 표면상태에 따른 내 스크래치성

다국어 초록 (Multilingual Abstract)

The polycarbonate is widely used for plastic products since it has high mechanical properties and it is transparent. However it has a limitation in its application because of soft surface, i.e. easy scratching. The degree of scratching is measured by pencil hardness tested and is different from surface condition. The dependency of pencil hardness according to the surface condition has been investigated by experiment and computer simulation. The surface conditions can be classified by surface roughness experimentally. Surface models for computer simulation were set to flat, convex, and concave types. Pressure and shear stress are set on the model surface for the boundary condition for structural analysis to investigate anti-scratching property. Low deformation model showed high pencil hardness comparing experiment and simulation. The flat type surface showed low pencil hardness whereas convex type surface showed high pencil hardness in experiment and simulation results. It is concluded that the anti-scratch property is dependent upon the surface condition.
