The aesthetics, integrity and durability of most polymers are susceptible to damage by scratching. With the increasing demand for their surface quality, the scratch resistance of polymers has caught significant attention in recent years. Alternating multilayered structure has been proved effective in reinforcing and toughening of polymers. In this work, the potential of this unique structure to improve scratch resistance of polymers was explored. Multilayer PVDF/PMMA sheets with total layer number of 32 and different layer thickness ratio was prepared, and their scratch behaviors were investigated under standardized progressive load scratch test (ASTM D7027/ISO 19252). Experimental results showed that scratch behaviors of pure PVDF and multilayer PVDF/PMMA differentiate greatly. A new scrach feature which was non-reported in literatures, namely restricted fish-scale pattern, was observed in multilayer samples and didn’t exsit in pure PVDF. What’s more, the critical normal load for onset of material removal increased by 80%-100% in multilayer samples as compared to pure PVDF, and the damage initiation location transferrd from in front to the rear end of scatch tip. Numerial modeling was conducted to uncover the mechanical mechanism for damage delay and location shift. It was revealed that changes in stress state and magnitude for material piled up in front of scratch tip is the primary cause for the observed phenomenons. This study offers a solution in designing polymers with improved scratch resistant property. Keywords: multilayer coextrusion, scratch resistance, mechanical deformation, numerical modeling
