In this study, preliminary simulations were performed to manufacture thermoplastic composites that can be processed by injection. For analysis, a basalt particulate-polymer composite model was manufactured and its elastic modulus, shear modulus, thermal expansion coefficient, and thermal conductivity were predicted using finite-element analysis (FEA) and micromechanics. Polypropylene (PP), polyamide 6, polyamide 66, and polyamide (PA) were employed as the polymer matrix, with the variations in their properties investigated based on the volume fraction of basalt. The polymer-basalt composite's properties were analyzed effectively using FEA and the micromechanics model. FEA was performed by constructing a 3D model based on the homogenization technique to analyze the effective properties. The micromechanics model was analyzed numerically using the mixture rule, and the Mital, Guth, and Halpin-Tsai models. As a result, it is best to analyze the effective properties of polymer-basalt composites using the Halpin-Tsai model, and it is necessary to conduct a comparative analysis through actual experiments. In the future, actual composite materials need to be developed and evaluated based on the findings of this study.
在本研究中，进行了初步模拟以制造可通过注塑加工的热塑性复合材料。为了进行分析，制造了玄武岩颗粒 - 聚合物复合模型，并使用有限元分析（FEA）和微观力学预测了其弹性模量、剪切模量、热膨胀系数和热导率。采用聚丙烯（PP）、聚酰胺6、聚酰胺66和聚酰胺（PA）作为聚合物基体，并根据玄武岩的体积分数研究了它们性能的变化。利用FEA和微观力学模型有效地分析了聚合物 - 玄武岩复合材料的性能。通过基于均匀化技术构建三维模型来进行FEA，以分析有效性能。使用混合法则以及米塔尔、古思和哈尔平 - 蔡模型对微观力学模型进行了数值分析。结果表明，使用哈尔平 - 蔡模型分析聚合物 - 玄武岩复合材料的有效性能最佳，并且有必要通过实际实验进行对比分析。未来，需要基于本研究的结果开发和评估实际的复合材料。
