Potential of Pineapple Leaf Fibers and Their Modifications for Development of Tile Composites

ABSTRACT

The research article focuses on succinct characterization of pineapple leaf fibers before and after different chemical modification techniques so as to ease its usage in developing light weight composite tiles for bathroom floor or wall tiles in building and construction industry. After the surface treatment namely, 7% alkali, 3% acrylic acid, and 1% silane treatment, fibers were analyzed through physical, chemical, morphological, mechanical, and thermal properties using various sophisticated instruments and concluded with the fact that in general, surface treatment helps in strengthen the fiber properties. Fibers with 7% alkali treatment exhibit maximum improvements, 55% increase in tensile strength, 40% increase in crystallinity index, 13% increase in density and 12.6% decrement in diameter. Similar enhancements in fiber quality were witnessed in physical, chemical, and thermogravimetric analysis. After 60% mass degradation of the fiber, fibers with 7% alkali treatment show better thermal stability till around 700°C.

摘要

本文着重研究了菠萝叶纤维在不同化学改性工艺前后的简明表征, 以便于在开发建筑业浴室地砖或墙砖用轻质复合砖时使用. 在经过7%碱, 3%丙烯酸和1%硅烷的表面处理后, 利用各种精密仪器对纤维的物理, 化学, 形态, 力学和热性能进行了分析, 得出结论:一般来说, 表面处理有助于增强纤维的性能. 碱处理量为7%时, 纤维的拉伸强度提高了55%, 结晶指数提高了40%, 密度提高了13%, 直径减小了12.6%. 在物理, 化学和热重分析中, 纤维质量也有类似的提高. 在纤维质量降解60%后, 经7%碱处理的纤维在700°C左右表现出较好的热稳定性.
