摘要：
The influence of surface texture pattern, i.e. distance between spherical bumps on the scratch behavior of injection molded polypropylene and polycarbonate has been investigated using a progressive load scratch test according to ISO 19252. The results show that the scratch properties can be enhanced when the distance between spherical bumps decreased. To understand the influence of distance between spherical bumps, polarizing optical microscope was used to observe the subsurface deformation. It was found that the size and depth of the deformation zone become smaller and shallower when the distance between spherical bumps decreased. This is the evidence that less stress concentration was generated under a scratch tip when the distance became shorter. POLYM. ENG. SCI., 52:18621867, 2012. (c) 2012 Society of Plastics Engineers
