ABSTRACT
A bio-fiber, Pithecellobium dulce is abundantly available in all over the world. It has a higher cellulose content (75.15 ± 0.26 wt.%) and low density (865 ± 26 kg/m3). To acquire fundamental knowledge about Pithecellobium dulce Fibers (PDFs), its physicochemical, crystalline, tensile, and morphological properties were examined and compared with other plant fibers. The chemical functional groups and crystallinity index (49.2 ± 2.45%) of the PDFs were obtained via Fourier transform-infrared analysis and X-ray diffraction, respectively. The Thermogravimetric analysis results of PDFs exhibit thermal stability up to 170°C. The surface morphology of PDF was analyzed by scanning electron microscopy. The attained results conclude that PDFs are appropriate fibers for acting as reinforcement in manufacturing of green composite product.
摘要
生物纤维，PithecellobiumDulce在世界各地都可获得。纤维素含量较高 (75.15±0.26重量%), 低密度 (865±26kg/m3)。为了获得关于PieleloLubul-dulCE纤维（PDFs）的基本知识，对其物理化学、结晶、拉伸和形态性质进行了研究，并与其它植物纤维进行了比较。分别用VIAFAFTIR和XRD对PDF的化学官能团和结晶度指数(49.2±2.45%) 进行了分析。PDF的热重分析结果表明，热稳定性可达170°C，用扫描电子显微镜（SEM）对PDF的表面形貌进行了分析。结果表明，PDFS是制造绿色复合材料的增强纤维。
