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.

聚丙烯基自增强复合材料的原子力显微镜研究

摘要 自增强复合材料是由增强芯和低熔点表层形成的聚合物材料，在固结步骤后充当基体。这些材料因其机械阻力和耐久性而在工业应用中得到广泛利用，这些材料本身受加工条件和聚合物成分的影响。在目前的工作中，使用两种类似的基于聚丙烯的商业织物来评估层压板压实后和使用原子力显微镜人工老化后的表面改性。结果与从扫描电子显微镜、透射电子显微镜、拉曼和热分析实验中获得的化学和物理-化学相互作用相关联。
