Synthesis and characterization of cellulosic fiber from red banana peduncle as reinforcement for potential applications

ABSTRACT

Natural fiber-reinforced polymer composites (NRPCs) are replacing many synthetic fibers because of their cheap availability and their hygienic, ecological, biodegradable, and sustainable properties. This work involved extraction of new cellulosic fibers from red banana peduncle (RBP) plant and investigated its chemical composition, physical, structural, thermal, and tensile properties. RBP fibers (RBPFs) have high specific strength and good binding properties due to their light weight andpresence of high cellulose (72.9 wt%), low lignin (10.01 wt%), and wax (0.32 wt%). X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) determined that RBPFs are rich in cellulose content with a crystallinity index (CI) of 72.3%. The density and diameter of the fibers were found to be about 0.896 g/cm³ and 15–250 μm, respectively. The fiber was thermally stable up to 230°C. Based on the results of this work, it seems that the properties of the fiber are a suitable candidate as a natural reinforcing material for the development of the biocomposite for potential applications.

摘要

天然纤维增强复合材料（nrpcs）代替了许多合成纤维由于其可用性、廉价、卫生、生态、生物降解性和可持续性。在这项工作中，新的纤维素纤维是从红香蕉梗提取（RBP）植物研究其化学组成、物理结构、热、和拉伸性能。由于红香蕉茎纤维轻（RBPF）和高纤维素的存在（72.9 wt%），低木质素（10.01 wt%）和蜡（0.32 wt%））给它的比强度高、良好的结合性能。X射线衍射（XRD）和傅里叶红外光谱（FTIR）确定红香蕉梗在纤维素含量丰富的结晶指数（IC）72.3%。纤维的密度和直径均约0.896克/立方厘米，15-250μm，分别。纤维的热稳定性高达230°C，根据这项工作的结果，似乎纤维的性能是一个合适的候选人作为一个天然的增强材料的发展，生物复合材料的潜在应用。
