摘要

摘要本研究的目的是生产和分析通过压缩成型制备的天然纤维基复合材料（剑麻/聚酯、红麻/聚酯和菠萝/聚酯）及其混合复合材料（剑麻/红麻/涤纶、红麻-菠萝/聚酯和剑麻/红麻麻/菠萝/涤纶）。使用硬度（肖氏D）、拉伸、弯曲和冲击（夏比）试验对这些复合材料进行了机械表征。用扫描电子显微镜（SEM）分析了纤维与基体的结合。在所有基于纤维的样品（剑麻/聚酯、红麻/聚酯和菠萝/聚酯）中，剑麻/涤纶表现出93.24Sd的高硬度值、43.00MPa的拉伸强度和约7.42kJ/m2的冲击强度，而菠萝/聚酯表现出83.21MPa的更好的弯曲强度。混杂复合材料显示出改进的机械性能。剑麻/红麻/菠萝/聚酯复合材料的力学性能分别为56.16MPa、1.71GPa和9.34kJ/m2。观察到剑麻/红麻/聚酯多层样品的最高弯曲强度为83.24MPa。

Mechanical and morphological characterization of sisal/kenaf/pineapple mat reinforced hybrid composites

Abstract The objective of this research is to produce and analyze natural fiber-based composites (sisal/polyester, kenaf/polyester, pineapple/polyester) and their hybrid composites (sisal/kenaf/polyester, kenaf/pineapple/polyester, and sisal/kenaf/pineapple/polyester) made by compression molding. These composites were characterized mechanically using hardness (shore D), tensile, flexural, and impact (Charpy) tests. Fiber matrix bonding was analyzed using Scanning Electron Microscopy (SEM). Among all the fiber-based samples (sisal/polyester, kenaf/polyester, and pineapple/polyester), sisal/polyester shows a high hardness value of 93.24 Sd, a tensile strength of 43.00 MPa, and an impact strength around 7.42 kJ/m2, while pineapple/polyester produces a better flexural strength of 83.21 MPa. Hybrid composites showed improved mechanical performance. The mechanical characteristics of the sisal/kenaf/pineapple/polyester hybrid composite were 56.16 MPa, 1.71 GPa, and 9.34 kJ/m2. The highest flexural strength of the Sisal/kenaf/polyester multi-layered samples was observed as 83.24 MPa.
