Abstract
The natural fiber reinforced composites are playing prominent role in many applications because of its various advantages such as eco-friendly, low cost, etc., with good mechanical properties. This article presents the effects of alkali treatment (NaOH) on mechanical and thermal properties of natural fiber reinforced polyester composites. Fibers were manually extracted followed by cleaning and drying at 80 °C. Fibers were treated using NaOH for four hours. Composite specimens were prepared using treated and untreated jute fiber and hemp fiber with varying weights such as 0, 2.5, 5 and 10 as reinforcement phase and polyester resin as matrix through hand lay-up technique. Tensile, flexural and impact tests were conducted on untreated and treated composites at room temperature as per ASTM standards. Fractographic analyses were reported using scanning electron microscopy (SEM). Thermal behavior of composites was studied using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Composites treated with NaOH showed improvement of mechanical and thermal properties.
