EnglishSelf-reinforced composites are polymeric materials formed by a reinforcement core and a low-melting point skin, which acts as a matrix after the consolidation step. These materials are widely exploited in industrial applications for their mechanical resistance and durability, which are themselves influenced by processing conditions and polymer composition. In the present work, two similar polypropylene-based commercial fabrics were used to evaluate the surface modifications after laminate compaction and after artificial aging using atomic force microscopy. The results were correlated with the chemical and physical-chemical interactions obtained from scanning electron microscopy, transmission electron microscopy, raman and thermal analysis experiments. Single tape consolidated laminate before and after aging displayed different superficial features that can explain the differences in the macroscopic behavior of the two products.

| Abstract: | Self-reinforced composites are polymeric materials formed by a reinforcement core and a low-melting point skin, which acts as a matrix after the consolidation step. These materials are widely exploited in industrial applications for their mechanical resistance and durability, which are themselves influenced by processing conditions and polymer composition. In the present work, two similar polypropylene-based commercial fabrics were used to evaluate the surface modifications after laminate compaction and after artificial aging using atomic force microscopy. The results were correlated with the chemical and physical-chemical interactions obtained from scanning electron microscopy, transmission electron microscopy, raman and thermal analysis experiments. Single tape consolidated laminate before and after aging displayed different superficial features that can explain the differences in the macroscopic behavior of the two products. |
