This study places emphasis on investigating the impact of integrating Sterculia foetida fiber and natural fillers into an epoxy matrix. An experimental investigation was conducted to examine the impact of incorporating natural fillers on the physical, mechanical, and thermal properties of a novel series of epoxy-based composites reinforced with fibers. The physical and mechanical properties of the composites produced in this study exhibited a higher level of concordance with the previously developed composites that incorporated natural fibers. It was determined that the composites containing 5% fillers and Sterculia foetida fiber exhibited low percentage error and moisture absorption. The composite manufactured with a 5% filler content exhibited superior mechanical qualities in terms of tensile strength, impact resistance, and Rockwell hardness compared to the other composites investigated in this study. The results of thermogravimetric analysis indicate that the incorporation of Sterculia bark and rice husk filler into the composites leads to an enhancement in thermal stability, specifically in relation to the Sterculia foetida content. The cellulose fiber utilized in this study exhibited thermal stability, indicating its appropriateness for usage in applications involving moderate temperatures.

本研究的重点是研究将胖大海纤维和天然填料整合到环氧基质中的影响。进行了一项实验研究，以检验掺入天然填料对一系列新型纤维增强环氧基复合材料的物理、机械和热性能的影响。本研究中生产的复合材料的物理和机械性能与之前开发的含有天然纤维的复合材料表现出更高的一致性。结果表明，含有 5% 填料和胖大海纤维的复合材料表现出较低的百分比误差和吸湿性。与本研究中研究的其他复合材料相比，采用 5% 填料含量制造的复合材料在拉伸强度、抗冲击性和洛氏硬度方面表现出优异的机械质量。热重分析结果表明，将胖大海树皮和稻壳填料掺入复合材料中可以提高热稳定性，特别是与胖大海含量有关。本研究中使用的纤维素纤维表现出热稳定性，表明其适合在涉及中等温度的应用中使用。
