Compendious Characterization of Chemically Treated Natural Fiber from Pineapple Leaves for Reinforcement in Polymer Composites

ABSTRACT

Nowadays, the research is more focused on natural fibers because of their comparable properties of biodegradability, environment friendly, ease of access, lightweight, and low cost. In this research paper, the effect of chemical treatment on morphological, physical, chemical, mechanical, and thermal properties of pineapple leaf fibers has been studied. Because of the highest amount of cellulosic content, this fiber is having great potential for mechanical and thermal strength. Initially, fibers were extracted using retting and scrapping method and thereafter treatment with different concentrations of alkali was performed. Characterization has been done to analyze its properties and found that the alkaline treatment leads to better mechanical and thermal properties but only up to 7% alkali concentration. After increasing the concentration above 7%, the properties start degrading because of the onset of fiber degradation at higher alkali application. Mercerization helps in making fiber more compatible with hydrophobic matrix resin and hence can be easily reinforced with polymeric matrix for specific composite applications.

摘要

由于天然纤维具有与合成纤维相当的性能，因此研究更侧重于天然纤维. 本文研究了化学处理对菠萝叶纤维不同性能的影响. 由于纤维素含量最高，这种纤维具有很大的机械强度和热强度潜力，通过对碱性处理纤维的分析证实了这一点，但只有高达7%的浓度，超过7%的浓度，纤维的性能开始退化，因为纤维开始降解. Adation.丝光处理有助于使纤维与疏水性基体更兼容，因此可以很容易地为特定的复合材料应用进行增强.
