当代研究人员正将注意力转向通过加入植物纤维来增强可生物降解基质(如聚乳酸)的结构完整性。新型纤维的使用正变得越来越普遍，以实现复合材料应用的特定需求，特别是在汽车和包装领域。机织织物由于具有更高的比强度和尺寸稳定性，通常被用于增强复合材料。在此背景下，我们开发了一种使用100%秋葵纤维的独特机织面料，并将其用于生产聚乳酸生物复合材料。这种方法是由于秋葵机织面料在复合材料制造领域的未开发潜力。为了优化复合材料的性能，选择了三种不同重量比例的秋葵机织物(OWF)，分别为20%、30%和40%。对所制得的复合材料进行了力学、形态和热性能表征。当聚乳酸中加入20%的OWF时，制得的复合材料具有最高的拉伸和热性能。扫描电子显微镜分析表明，20%的OWF复合材料具有良好的纤维-基质结合力，提高了各项性能的功效。研究结果表明，OWF/PLA复合材料是一种很有前途的绿色材料，在汽车和包装工业中具有广阔的应用前景。亮点：采用100%秋葵机织织物制成了一种新型复合材料，当织物含量为20%时，复合材料的力学性能最好，当织物含量为20%时，复合材料的热性能也得到了优化。扫描电子显微镜证实，20%的OWF/解放军复合材料具有较强的纤维-基体结合能力，适合于汽车和包装应用。
Contemporary researchers are directing attention towards enhancing the structural integrity of biodegradable matrices, such as polylactic acid (PLA), through the incorporation of plant fibers. The utilization of novel fibers is becoming more prevalent to achieve the specific demands of composite applications, particularly in the automotive and packaging fields. Woven fabrics are commonly favored for reinforcing composites due to their elevated specific strength and dimensional stability. In pursuit of this context, we have developed a unique woven fabric using 100% okra fiber and utilized it in the production of PLA biocomposites. This approach was made due to the unexplored potential of okra woven fabric in the field of composite manufacturing. To optimize the performance of the composites, three distinct weight proportions of okra woven fabric (OWF) were chosen, including 20%, 30%, and 40%. The obtained composites were mechanically, morphologically, and thermally characterized. The manufactured composite's maximum tensile and thermal property was attained by adding 20% OWF to the PLA. Scanning electron microscopy analysis revealed that 20% OWF composite possessed superior fiber‐matrix adhesion, improving all properties' efficacy. The overall findings reveal that the OWF/PLA composites are promising as a green material for applications in the automotive and packaging industries.HighlightsA novel class of composite has been created using 100% okra woven fabric.The composite with 20% fabric content showed the best mechanical properties.Thermal properties of composites are also optimized using 20% fabric content.SEM confirms the strong fiber‐matrix bonding of 20% OWF/PLA composites.The composites are suitable for automotive and packaging applications.
