Abstract

This study investigates the effect of winding angle on the mechanical properties of kenaf fiber reinforced epoxy composite which is produced by filament winding technique. This study investigates the effect of 45° and 63° angle variations of fiber winding placement fixed by 2 layers using kenaf fiber and glass fiber as raw materials. Mechanical properties of the sample were determined by using tensile test (ASTM D3036), compressive test (ASTM D695) and 3-point flexural bending (ASTM D790). Both mechanical properties of kenaf fiber and glass fiber were compared to determine the possibility of kenaf fiber to replace glass fiber in composite industries in the future. From this study, all result showed that treated kenaf fiber has higher mechanical properties compared to untreated kenaf due to improvement of NaOH treatment on kenaf fiber. Result also has showed that higher winding angle, which is 63° has higher mechanical properties as compared to lower angle placement of 45° of the winding composites.
