ABSTRACT Functionally graded material (FGM) are a composite material which consists of filler material and matrix. FGM properties vary along the composition gradient. Common FGMs employs one type of filler material with specific properties. The application of two types of filler materials makes an opportunity to achieve the advantages of two types of filler materials, simultaneously. This study focuses on the FGMs with two types of filler materials and polyester resin (polymer) as a matrix. In this regard, the centrifugal technique is employed to fabricate dual filler functionally graded polymer materials (DF-FGPM). Copper-Silicon Carbide and Iron-Fused Alumina are used as two cases of dual filler materials. The microstructure and flexural strength of samples are evaluated using the image processing method and three-point bending test (according to ASTM D790), respectively. The results of particle distribution showed the different behavior of particles which can enhance surface and volumetric properties, simultaneously. Also and because of the importance of the interfacial layer in the composite structure, developed FGM presented achievements in the B type of loading during the three-point bending test.

双填料功能梯度聚合物材料——制造工艺和特性

摘要功能梯度材料（FGM）是一种复合材料，由填充材料和基体组成。FGM 属性随成分梯度变化。常见的 FGM 使用一种具有特定属性的填充材料。两种填充材料的应用为同时实现两种填充材料的优点提供了机会。本研究的重点是具有两种填充材料和聚酯树脂（聚合物）作为基质的 FGM。在这方面，离心技术用于制造双填料功能梯度聚合物材料（DF-FGPM）。铜碳化硅和铁熔氧化铝被用作双填充材料的两种情况。分别使用图像处理方法和三点弯曲试验（根据 ASTM D790）评估样品的微观结构和弯曲强度。粒子分布的结果表明粒子的不同行为可以同时增强表面和体积特性。此外，由于界面层在复合结构中的重要性，开发的 FGM 在三点弯曲试验期间在 B 型加载方面取得了成果。
