ABSTRACT
This article presents the characteristics of Carica papaya fibers (CPFs) extracted from the bark of the perennial papaya plant. Detailed chemical compositions of CPFs such as cellulose, lignin, ash, moisture, and wax contents were established and determined by using standard methods. Further, chemical groups, crystalline structure, surface roughness, and thermal stability of CPFs were examined using Fourier transform infrared analysis, X-ray diffraction, atomic force microscope, and thermogravimetric analysis, respectively. The physico-chemical properties of CPFs, crystallinity index (56.34%), cellulose content (38.71 wt. %), hemicellulose (11.8%), and density (943 kg/m3) were compared to those properties of other natural fibers. The results suggest that the biodegradable CPFs can be used as a potential reinforcemnet in the polymer matrix composite structure.
摘要
本文介绍了番木瓜纤维的特性(CPFS)从多年生植物的树皮中提取的木瓜。番木瓜纤维如纤维素、木质素、灰详细的化学成分、水分和蜡质含量建立并采用标准方法测定。此外,化学组、晶体结构、表面粗糙度和番木瓜纤维的热稳定性均采用傅里叶变换红外分析检查,X射线衍射、原子力显微镜、热重分析。番木瓜纤维的理化性质、结晶度指数(56.34%),纤维素含量(38.71重量%)、半纤维素(11.8%)和密度(943 kg/m3)相比其他天然纤维的性能,结果表明,可生物降解的番木瓜纤维可作为聚合物基体复合结构潜在的增强。
