Title : Effect of Alkaline Treatment and Fiber Orientation on Mechanical Properties of Biocomposite Sansevieria trifasciata Fibre/Vinyl Ester

Abstract :

Using natural fibres like Sansevieria trifasciata can be an option to reduce energy consumption compared to synthetic fibre that requires a high consumption of energy since it contributes to the mechanical properties of composites. Therefore, an observation was done to know the effect of alkaline treatment with 3% NaOH on Sansevieria trifasciata fibre obtained through mechanical retting method, in which the composites consist of Sansevieria trifasciata with vinyl ester matrix. In this study, the modified fibre orientations were the random and the unidirectional ones, while the volume fraction used was 0%, 5%, 10%, and 15%. Several tests were carried out namely tensile tests, impact tests, density tests and observations through scanning electron microscopy (SEM). The results of this study found that the value of tensile strength could increase up to 31.7%, the stiffness could increase up to 13% and the toughness could increase 49.6% with the addition of alkaline treatment on the fibre. There was also an increase in mechanical properties with the addition of volume friction, in which the largest increase occurred in the volume fraction of 15%
