This study examines natural and synthetic fibers' mechanical properties and performance. Current mechanical property investigations focus on flat panels rather than tubular profiles. The investigation focuses on tubular hollow specimens using the filament winding technique with kenaf and fiberglass fibers. The study compares the mechanical properties of tensile, compression, toughness, morphology, and water content. The results show that fiberglass outperforms kenaf fiber as a natural fiber candidate in the results for average tensile strength by 79.20%, average modulus by 79.10%, average tensile strain by 46.70%, average tensile modulus by 53.70%, and Toughness by 89.30%. However, the study highlights a few areas where natural fibers show superiority over fiberglass. Further investigations are necessary to enhance the mechanical performance of natural fibers. In summary, the usefulness of natural fibers has been demonstrated in hollow specimens, but their overall performance has not been fully explored yet.
本研究考察了天然纤维和合成纤维的力学性能与表现。目前的力学性能研究主要关注平板材料，而非管状结构。本研究采用长丝缠绕技术，以剑麻纤维和玻璃纤维为原料，对管状中空试样进行了测试。研究比较了拉伸强度、压缩强度、韧性、形态学及含水量等机械性能指标。结果表明，在平均抗拉强度、平均弹性模量、平均拉伸应变、平均拉伸模量以及韧性方面，玻璃纤维在天然纤维候选材料中均优于剑麻纤维，分别高出79.20%、79.10%、46.70%、53.70%和89.30%。然而，研究也指出，天然纤维在某些方面仍优于玻璃纤维。因此，有必要进一步开展研究，以提升天然纤维的力学性能。综上所述，天然纤维在中空试样的应用具有实际价值，但其整体性能尚未得到充分探索。 |
