ABSTRACT
The increasing environmental awareness has directed attention of the researchers towards the field of natural fiber composites. The aim of this investigation is to understand the physico-chemical properties of fibers extracted from the bark of the Dichrostachys Cinerea (DC) plant. Dichrostachys Cinerea fibers (DCFs) has cellulose (72.4 wt. %), hemicellulose (13.08 wt. %), lignin (16.89 wt. %), density (1240 kg/m3), crystallinity index (57.82%), and tensile strength (873 ± 14 MPa). Besides the cellulose degradation of DCFs at 359.3° vide by the thermo-gravimetric analysis and chemical groups are identified by Fourier transform analysis. Eventually the characterization results of DCFs strongly show the possibility of reinforcement in polymer matrices.
摘要
随着环保意识的增强,研究人员对天然纤维复合材料领域给予了更多关注。本研究旨在考察从代儿茶(DC)植物树皮提取的纤维的物理化学性质。代儿茶纤维(DCF)包含纤维素(重量比72.4%)、半纤维素(重量比13.08%)、木质素(重量比16.89%)、密度(1240kg/m3)、结晶度指数(57.82%)和拉伸强度(873 ± 14 MPa)。在研究中,除了通过热重分析在359.3°范围内DCF的纤维素降解外,还通过傅立叶变换分析鉴定了化学基团。最后,DCF的表征结果强烈显示了在聚合物基质中增强具有可能性。
