In this work, two varying types of composites with a fixed weight percentage of plain woven glass fiber and epoxy reinforced with four different types of filler materials such as one with CaCO₃-Al₂O₃-MgO-TiO₂ and another with CaCO₃-Al₂O₃-MgO-CuO at different weight ratios (5, 10 and 15 gm) are studied. The composite specimens required for different tests are fabricated in conventional wet hand lay-up technique followed by same light compression molding process as per ASTM standards. Thermal stability and mechanical properties such as ultimate tensile strength, flexural strength and impact strength of the composites were investigated and hybrid effect of filler materials and their dispersion efficiency was observed through the examination of their microstructure with Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM) and Thermal Gravimetric Analysis (TGA). From the results it is found that tensile strength, flexural strength and impact strength are increased with increasing amount of filler materials. However, significant improvement in thermal stability and mechanical properties such as tensile strength (20.353%), flexural strength (26.652%) and impact strength (12.935%) is observed in case of the composite made of CuO than that of the composite made of TiO₂.

在这项工作中，两个不同类型的复合材料的使用普通编织玻璃纤维和环氧树脂的固定重量百分比钢筋四种不同类型的填充材料，例如一个与碳酸钙的₃ -Al ₂ ö ₃ -MgO-TIO ₂，另一个的CaCO ₃ -铝₂ O ₃研究了不同重量比（5、10和15 gm）的-MgO-CuO。不同测试所需的复合材料样品采用常规的湿手铺层技术制造，然后按照ASTM标准进行相同的轻压成型工艺。研究了复合材料的热稳定性和机械性能，如极限拉伸强度，挠曲强度和冲击强度，并通过傅立叶变换红外光谱（FTIR），扫描电子学检查了填料的微观结构，观察了填料的杂化效应和分散效率。显微镜（SEM）和热重分析（TGA）。从结果发现，抗张强度，弯曲强度和冲击强度随着填充材料的增加而增加。然而，₂。
