In this research, the physical, mechanical and morphological properties of oil palm empty fruit bunch (EFB) mat/woven kenaf fabric-reinforced epoxy composites have been investigated. The oil palm EFB/woven kenaf fabrics were varied, with weight ratios of 50/0 (T1), 35/15 (T2), 25/25 (T3), 15/35 (T4) and 0/50 (T5). The composites were fabricated using a simple hand lay-up technique followed by hot pressing. The result obtained shows that an increase in kenaf fiber content exhibited higher tensile and flexural properties. On the other hand, the opposite trend was observed in the impact strength of hybrid composites, where an increase in kenaf fiber content reduced the impact strength. This can be corroborated with the physical properties analysis, where a higher void content, water absorption and thickness swelling were observed for pure oil palm EFB (T1) composites compared to other samples. The scanning electron microscopy analysis results clearly show the different failure modes of the tensile fractured samples. Statistical analysis was performed using one-way ANOVA and shows significant differences between the obtained results.
在本研究中，对油棕空果串（EFB）毡/编织红麻织物增强环氧复合材料的物理、机械和形态性能进行了研究。油棕EFB/编织红麻织物的比例各不相同，重量比分别为50/0（T1）、35/15（T2）、25/25（T3）、15/35（T4）和0/50（T5）。采用简单的手糊工艺并随后进行热压来制备复合材料。所得结果表明，红麻纤维含量的增加表现出更高的拉伸和弯曲性能。另一方面，在混杂复合材料的冲击强度方面观察到相反的趋势，即红麻纤维含量的增加降低了冲击强度。这可以通过物理性能分析得到证实，与其他样品相比，纯油棕EFB（T1）复合材料观察到更高的孔隙率、吸水率和厚度膨胀率。扫描电子显微镜分析结果清楚地显示了拉伸断裂样品的不同失效模式。使用单因素方差分析进行统计分析，结果显示所得结果之间存在显著差异。
