Abstract

The purpose of this study was to evaluate the effects of incorporation of the rice husk ashes and titanium dioxide on properties of acrylonitrile butadiene styrene (ABS). The incorporation of rice husk ashes (RHA) (2.5 wt.%) and titanium dioxide (2.5; 5.0 wt.%) into ABS matrix was carried out by melting extrusion process using a twin-screw extruder. Neat ABS and its composites filaments for FDM 3D printing were produced using the melting extrusion process to obtain specimens for tests. The properties of ABS/RHA/TiO2 composite samples were investigated by the properties of the ABS/RHA/TiO2 composite samples were evaluated using tensile tests, SEM, XRD analysis, Charpy impact test, and water contact angle measurements. This study contributes to our understanding of the behavior of ABS composites containing RHA and TiO2 for various industrial applications. (AU)
