This work deals with the investigation of the synergistic effect of bagasse ash with sisal-banana-kenaf-flax fibers reinforced epoxy composite for their flexural behavior. The composites with three combinations of hybrid fibers viz. sisal/kenaf (HSK), banana/kenaf (HBK), and banana/flax (HBF) with bagasse ash (BGA) as filler material are fabricated using vacuum bag assisted resin transfer molding. Experiments were conducted based on L27 orthogonal array to understand the influence of control factor viz. fiber volume, alkali concentration & BGA over output response. X-ray micro computed tomography analysis was conducted over the developed sample to infer the uniform dispersion of fiber and filler material. The experimental results reveal that the addition of fiber up to 30 vol% depicts better strength and further addition results in a negative impact. Increasing in order of BGA decreases the flexural strength of the developed composites.

这项工作涉及甘蔗渣灰与剑麻，香蕉，洋麻，亚麻纤维增强的环氧复合材料的弯曲行为的协同作用。具有混杂纤维的三种组合的复合物即。剑麻/洋麻（HSK），香蕉/洋麻（HBK）和香蕉/亚麻（HBF），以蔗渣灰（BGA）作为填充材料，是通过真空袋辅助树脂传递模塑法制成的。基于L27正交阵列进行实验，以了解控制因子viz的影响。纤维量，碱浓度和BGA超过输出响应。X对展开的样品进行了射线微计算机断层扫描分析，以推断纤维和填料的均匀分散性。实验结果表明，添加至多30 vol％的纤维表现出更好的强度，进一步添加会产生负面影响。BGA的顺序增加会降低已开发复合材料的抗弯强度。
