Hybrid composites are a category of composites in which more than one types of fiber are used to reinforce the matrix. In this work, the mechanical properties of jute woven & and carbon-jute woven reinforced polymer matrix hybrid composites were evaluated to assess a comparative study between the two configurations varying the stacking sequences. Specimens of composites were prepared by hand layup process. To observe the effect of fiber weight fraction on properties, two types of composites were made having matrix-fiber weight fractions of 85:15 & and 80:20. Moreover, by altering the stacking sequences of the composites, these properties were also examined for the carbon-jute reinforced polymer matrix composites. It was observed that a hybrid jute-carbon composite having a stacking sequence of j/c/j/c/j and weight fraction ratio of 80:20 exhibited a better tensile strength of 108.795(10.885) MPa and Young’s modulus of 6.052(0.489) GPa. Superior flexural strength of 150.41 (±7.501) MPa and flexural modulus of 6.845(±0.825) GPA were found in hybrid jute-carbon composite having stacking sequence of j/c/j/c/j/c/j/c/j that has a weight fraction ratio of 80:20. In both cases, better mechanical properties were found for hybrid composites with higher fiber content and having alternate stacking sequences.

堆叠顺序和重量分数对机织黄麻和机织碳-黄麻增强聚酯复合材料拉伸和弯曲性能的影响

混合复合材料是一类复合材料，其中使用多种类型的纤维来增强基体。在这项工作中，评估了黄麻编织和碳-黄麻编织增强聚合物基混合复合材料的机械性能，以评估改变堆叠顺序的两种配置之间的比较研究。复合材料样品通过手糊工艺制备。为了观察纤维重量分数对性能的影响，制备了两种类型的复合材料，其基体纤维重量分数分别为 85:15 和 80:20。此外，通过改变复合材料的堆叠顺序，还检查了碳黄麻增强聚合物基复合材料的这些性能。结果表明，堆叠顺序为 j/c/j/c/j、重量分数为 80:20 的杂化黄麻-碳复合材料表现出更好的拉伸强度（108.795（10.885）MPa）和杨氏模量（6.052（0.489））。 ) GPa。堆叠顺序为 j/c/j/c/j/c/j/c/j 的混合黄麻-碳复合材料具有 150.41 (±7.501) MPa 的优异弯曲强度和 6.845(±0.825) GPA 的弯曲模量，其重量分数比为80:20。在这两种情况下，纤维含量较高且具有交替堆叠顺序的混合复合材料具有更好的机械性能。
