在本研究中，油棕空果束（OPEFB）纤维取自一棵25岁的油棕树。采用化学-机械工艺从OPEFB中分离出纤维素纳米纤维（CNF），并将其作为环氧树脂基体的增强材料。在环氧基中应用不同的CNF加载百分比（0 - 0.75%）来探索使用OPEFB-CNF作为增强材料的潜力。研究了OPEFB纳米纤维增强环氧复合材料的形态、力学、物理和热性能。结果表明，0.25%和0.5% CNF载荷在复合基质中分布均匀，分散良好。相反，当CNF负载为0.75%时，基质中出现了团聚现象。对cnf增强环氧复合材料在不同载荷下的吸水性能的测定表明，复合材料的物理性能随着增强载荷的增加而增加。此外，cnf增强复合材料的力学和热性能分析表明，OPEFB-CNF的加入提高了0.5%载荷下的力学性能和热稳定性。
In the present study, oil palm empty fruit bunch (OPEFB) fibers were taken from a 25-year-old oil palm tree. The cellulosic nanofiber (CNF) was isolated from the OPEFB using a chemo-mechanical process and utilized as reinforcement in an epoxy matrix. Various CNF loading percentages (0 to 0.75%) were applied in the epoxy matrix to explore the potential of using OPEFB-CNF as reinforcement. The morphological, mechanical, physical, and thermal characteristics of the OPEFB nanofiber-reinforced epoxy composites were evaluated. Results showed that the 0.25% and 0.5% CNF loadings were homogenously distributed and well-dispersed in the composite matrix. Conversely, agglomeration was detected in the matrix with 0.75% CNF loading. Determination of the water absorption behavior of CNF-reinforced epoxy composites at various loadings revealed that the physical properties of the composites increased with reinforcement loading. Furthermore, the analyses of the mechanical and thermal properties of the CNF-reinforced composites revealed that the incorporation of OPEFB-CNF enhanced the mechanical performance and thermal stability up to 0.5% loading.
