摘要

各行各业都在使用天然纤维(NF)增强复合材料。环氧树脂基体复合材料采用手糊工艺成型,使用的编织纤维来自阿尔朱纳树(Terminalia Arjuna)纤维和油橄榄(Moringa Oleifera)果实纤维。根据织物的重量,复合板的层数从 7 层到 13 层不等。对拉伸、弯曲、冲击、压缩、短梁剪切强度、断裂韧性和吸水性(WA)进行了评估。利用扫描电子显微镜(SEM)分析法对制作的复合材料进行了检测,以检查断裂形态并评估界面强度。调查显示,增加纤维层的数量可提高复合材料的物理和机械性能。复合材料的拉伸强度提高了 25%,达到 62.35 兆帕,而 10 天后的吸水率为 18.4%。因此,这些研究结果表明,所制造的复合材料非常适合应用于要求中等承载能力的结构部件和汽车车身部件。

Investigation of mechanical properties of terminalia arjuna and moringa oleifera fiber reinforced epoxy composite

Various sectors are utilizing composites reinforced with natural fibers (NF). Composite materials with an epoxy matrix have been mould with hand layup process using woven fibers from the Terminalia Arjuna fiber and Moringa Oleifera fruit fibers. The composite panels were manufactured using a variable number of layers, ranging from 7 to 13, depending on the fabric's weight. An assessment has been conducted on the tensile, bending, impact, compression, short beam shear strength, fracture toughness, and water-absorption (WA). The composites that were created were examined utilizing SEM analysis to examine the fractured morphology and assess the strength of the interface. The investigation revealed that augmenting the quantity of fiber layers enhanced the physical and mechanical properties of the composites. The tensile strength of the composites increased by 25% to 62.35 MPa with 11 layers, while water absorption was found to be 18.4% after 10 days. Therefore, these findings suggest that the fabricated composites are well-suited for applications in structural components and automotive body parts requiring moderate load-bearing capacity.

期刊介绍: Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology. As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology, including: polymer synthesis; polymer reactions; polymerization kinetics; polymer physics; morphology; structure-property relationships; polymer analysis and characterization; physical and mechanical properties; electrical and optical properties; polymer processing and rheology; application of polymers; supramolecular science of polymers; polymer composites.
