摘要：
The influence of the substrate material and adhesion of the interface on the scratch resistance of poly (methylmethacrylate) (PMMA) in a multilayer system was explored using scratch tests and finite-element analysis. Experimental results showed that the influence of the substrate material on the scratch resistance of PMMA was not significant if the top layer was a PMMA bulk material. If the top layer was a PMMA film, a hard substrate (such as steel) reduced its scratch resistance and puncture occurred after material removal. Compared with a two-layer PMMA/PMMA system (without glue), the critical loads for scratch damage to a PMMA/glue/PMMA system were reduced under linearly increasing normal load scratch tests. Puncture was not found after material removal in the PMMA/glue/PMMA system. This study provides significance for design of scratch-resistant multilayer polymer systems. (c) 2020 The Author(s).
