Abstract :
Non-cellulosic substances such as lignin, waxes, hemicelluloses and pectin present in the hemp fiber structure affect the mechanical performance of composites due to poor fiber/matrix adhesion. For this reason, hemp fiber is often pretreated before use in composite reinforcement. In this study, an ultrasonic-assisted pretreatment was applied using quaternary ammonium hydroxide to increase the degradation rate of non-cellulosic substances in hemp fiber. Cetyl trimethyl ammonium chloride (CTAC) concentrations ranging between 1 and 8% w/w were used with a constant (10% w/w) NaOH concentration. Hemp fiber surfaces were examined by scanning electron microscope (SEM). The results showed that ultrasonication-assisted alkali treatment removed non-cellulosic substances from the fiber surface. Fourier-transform infrared spectroscopy (FT-IR) and Thermogravimetric analysis (TGA) studies also confirmed the removal of these substances from hemp fiber.
