Influence of surface texture on scratch behaviors of injection molded plastics Conference Paper

abstract

• A standard scratch test based on ISO 19252 was conducted with injection molded plastics using a spherical shape scratch tip with a diameter of 5 mm. Effect of spherical patterns distance on scratch behavior was investigated. The spherical pattern size was 0.8 mm in diameter and the distance was varied in 0.5, 0.9 and 1.2 mm. The critical normal load for onset of pattern shape change decreased with increasing distance between spherical patterns, i.e. shorter distance led to higher scratch resistances. Polarizing optical microscope (POM) observation showed that yielded zone size in sub-surface increased as the distance between spherical patterns increased.
