摘要

本研究评估了碱性处理和体积分数对由枣椰树纤维(FPDS)增强的高密度聚乙烯(HDPE)基体组成的生物复合材料的影响。对未经处理和经 NaOH 处理的生物复合材料进行了拉伸试验。此外,还使用扫描电子显微镜(SEM)和 X 射线衍射(XRD)对纤维进行了分析。结果表明,与高密度聚乙烯相比,该材料具有更高的强度和刚度,尽管有限的塑性使其变脆。NaOH 处理增强了某些机械性能。进一步的评估包括硬度、密度、熔融指数和伊佐德冲击试验。对两种体积分数(20% 和 25%)的 FPDS 进行了测试。该研究建立了经验预测与人工神经网络(ANN)模型之间的相关性。值得注意的是,由两个输入因子、10 个隐藏节点和一个输出组成的人工神经网络结构提供了机械性能分析。这项研究突出了 FPDS 增强高密度聚乙烯生物复合材料的潜力,强调了其在不同处理和纤维水平下的机械性能。

Assessment of mechanical and physicochemical properties of palm fiber composites: Effect of alkaline treatment and volume alterations
This study assesses the impact of alkaline treatments and volume fractions on biocomposites composed of a high-density polyethylene (HDPE) matrix reinforced with date palm tree fibers (FPDS). Tensile tests were conducted on both untreated and NaOH-treated biocomposites. Additionally, fiber analysis was performed using scanning electron microscopy (SEM) and X-ray diffraction (XRD). The results reveal higher strength and stiffness compared to HDPE, albeit with limited plasticity making the material brittle. The NaOH treatment enhances certain mechanical properties. Further assessments encompassed hardness, density, melt index, and Izod impact tests. Two volume fractions, 20% and 25%, of FPDS were tested. The study establishes a correlation between empirical predictions and artificial neural network (ANN) models. Notably, an ANN architecture consisting of two input factors, 10 hidden nodes, and one output provides the analysis of mechanical properties. This investigation highlights the potential of FPDS-reinforced HDPE biocomposites, emphasizing their mechanical performance under various treatments and fiber levels.
