In recent years, there has been a growing demand for environmentally friendly materials as alternatives to synthetic fibers, which pose significant environmental hazards due to their non-biodegradability. Natural fibers, such as Luffa Cylindrica, have gained attention due to their sustainability, lightweight properties, and biodegradability. However, their poor mechanical performance in composite applications limits their widespread use. The novelty of this study lies in the exploration of various treatments aimed at improving the tensile properties of Luffa Cylindrica fibers (LCFs), a relatively under-explored natural fiber. The research investigates the effects of immersion treatments in mineral water, seawater, vinegar (CH₃COOH), sodium bicarbonate (NaHCO₃), and ethanol (C₂H₆O) on the tensile strength, surface morphology, and absorption properties of these fibers. The study highlights that untreated LCFs exhibit superior tensile strength (5.59 MPa) compared to treated fibers. Additionally, the statistical analysis utilizing two-parameter Weibull distribution offers novel insights into the mechanical properties of treated LCFs, confirming significant variations in fiber behavior with different treatments. This study contributes to the understanding of surface modifications that enhance the performance of Luffa Cylindrica fibers in composite materials, a promising step towards their industrial application.
近年来，对环保材料作为合成纤维替代品的需求不断增长，合成纤维因其不可生物降解性而对环境造成重大危害。天然纤维，如丝瓜，因其可持续性、轻质特性和生物降解性而受到关注。然而，它们在复合材料应用中的机械性能较差，限制了其广泛使用。本研究的新颖之处在于探索各种旨在改善丝瓜纤维（LCFs）拉伸性能的处理方法，丝瓜纤维是一种相对未被充分研究的天然纤维。该研究调查了在矿泉水、海水、醋（CH₃COOH）、碳酸氢钠（NaHCO₃）和乙醇（C₂H₆O）中浸泡处理对这些纤维的拉伸强度、表面形态和吸收性能的影响。研究强调，未处理的LCFs比处理过的纤维表现出更高的拉伸强度（5.59MPa）。此外，利用双参数威布尔分布的统计分析为处理过的LCFs的机械性能提供了新的见解，证实了不同处理方式下纤维行为的显著差异。本研究有助于理解表面改性如何提高丝瓜纤维在复合材料中的性能，这是朝着其工业应用迈出的有希望的一步。
