Abstract

Researches on novel natural fibers in polymer-based composites will help promote the invention of novel reinforcement and expand their possible applications. Herein, in this study, novel cellulosic fibers were extracted from the stem of manau rattan (Calamus manan) by mechanical separation. The chemical, thermal, mechanical and morphological properties of manau rattan fibers were comprehensively analyzed and studied by Fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), single fiber tensile test and scanning electron microscopy (SEM). Component analysis results showed that the cellulose, hemicellulose and lignin contents of C. manan fibers were 42wt%, 20wt%, and 27wt%, respectively. The surface of the rattan fiber was hydrophilic according to the oxygen/carbon ratio of 0.49. The C. manan has a crystalline index of 48.28%, inducing a maximum degradation temperature of 332.8 °C. This reveals that it can be used as a reinforcement for thermoplastic composites whose operating temperature is below 300 °C. The average tensile strength can reach (273.28 ± 52.88) MPa, which is beneficial to improve the mechanical properties of rattan fiber reinforced composites. The SEM images displayed the rough surface of the fiber, which helped to enhance the interfacial adhesion between the fibers and matrices in composites. These results indicate the great potential of C. manan fibers as the reinforcement in polymer-based composites.

天然藤纤维作为聚合物基复合材料潜在增强材料的特性研究
聚合物基复合材料中新型天然纤维的研究将有助于促进新型增强材料的发明和拓展其应用前景。本研究采用机械分离的方法从麻藤茎中提取新型纤维素纤维。采用傅里叶变换红外光谱(FT-IR)、x射线光电子能谱(XPS)、x射线衍射(XRD)、热重分析(TGA)、单纤维拉伸试验和扫描电镜(SEM)等方法,对麻藤纤维的化学、热、力学和形态等性能进行了综合分析和研究。组分分析结果表明,甘露聚糖纤维的纤维素、半纤维素和木质素含量分别为42%、20%和27wt%。藤纤维表面的氧碳比为0.49,具有亲水性。C. manan的结晶指数为48.28%,最大降解温度为332.8℃。这表明它可以用作工作温度低于300℃的热塑性复合材料的增强材料。平均抗拉强度可达(273.28±52.88)MPa,有利于提高藤纤维增强复合材料的力学性能。SEM图像显示纤维表面粗糙,这有助于增强复合材料中纤维与基体之间的界面附着力。这些结果表明甘露聚糖纤维在聚合物基复合材料中具有很大的增强潜力。
