The scratch deformation behavior of neat and filler-containing polypropylene composites has been studied by electron microscope and atomic force microscopy techniques. A comparative assessment of scratch damage is made in terms of average width of the plastically deformed region and morphology of the scratch tracks. The study indicates the tendency of scratch deformation of polypropylene composites. The resistance to scratch deformation under conditions of scratch test is dependent on factors such as rubber, additives, filler content, and particle size of filler. Rubber and filler containing polypropylene are characteristic by a less resistance to mechanical deformation than neat polypropylene. The smaller particle size of filler, the greater resistance of scratch deformation. In addition, if polypropylene contains additive, it will exhibit significantly reduced width of scratch. |
