Increased concern for human health and the environment has pushed various industries to adopt new approaches towards satisfying modern regulations. Strategies to achieve these approaches include utilizing lightweight materials, repurposing waste materials, and substituting synthetic polymers with bio-based counterparts. This study investigates the effects of treated fly ash (C) and bio-based polyamide 10.10 (PA10) on the thermal, morphological, and mechanical properties of glass fiber (GF)-reinforced polyamide 6 (PA6). Our main objective was to develop a composite that would allow for the partial replacement of glass fiber in reinforced polyamide 6 composites (PA6-30G) while maintaining a favorable balance of mechanical properties. Composites processed via melt processing demonstrated enhanced mechanical properties compared to PA6-30G. Notably, significant improvements were observed in impact strength and tensile strain at break. The addition of PA10 resulted in increases of 18% in impact strength and 35% in tensile strain relative to PA6-30G. Complementary, structural and morphological analyses confirmed strong interfacial interactions within the composite matrix. These findings indicate that a PA6/PA10 hybrid composite may represent a viable alternative material for potential automotive applications.
对人类健康和环境的日益关注促使各行业采用新方法以满足现代法规要求。实现这些方法的策略包括使用轻质材料、将废料重新利用以及用生物基材料替代合成聚合物。本研究调查了处理后的粉煤灰（C）和生物基聚酰胺10.10（PA10）对玻璃纤维（GF）增强聚酰胺6（PA6）的热性能、形态和力学性能的影响。我们的主要目标是开发一种复合材料，该复合材料能够在增强聚酰胺6复合材料（PA6 - 30G）中部分替代玻璃纤维，同时保持良好的力学性能平衡。通过熔融加工制备的复合材料与PA6 - 30G相比，力学性能得到了增强。值得注意的是，冲击强度和断裂拉伸应变有显著提高。相对于PA6 - 30G，添加PA10使冲击强度提高了18%，断裂拉伸应变提高了35%。补充的结构和形态分析证实了复合基质内有很强的界面相互作用。这些发现表明，PA6/PA10混杂复合材料可能是潜在汽车应用的一种可行替代材料。
