Abstract
Green Composites comprising of lignocellulosic fibers are low cost sustainable materials. They are environmentally friendly alternative to the use of glass fibers as reinforcement in engineering composites. In order to improve the interfacial interaction with the matrix, lignocellulosic fibers are subjected to fiber surface modification. The aim of this work is to study the influence of corona discharge treatment on morphology and mechanical properties of neutral fibers. In this respect, Aloe Vera fibers were treated with corona discharge during 5, 10, and 15 min. Scanning electron microscopy (SEM) micrograph had shown the rough surface morphology and degradation of fibers due to etching mechanism causes by corona. Furthermore, mechanical testing on treated fibers showed a decrease of elastic modulus and ultimate tensile strength. The influence of corona treatment on fibers was also studied by Fourier transform infrared-spectroscopy (FT-IR) and X-ray diffraction (XRD).
