Samanea saman (SS) ower particulates were lled in Polylactic acid (PLA) composites were fabricated with different 0, 10, and 20 wt.% through the injection molding process. The elemental composition and morphology of SS PLA composites were studied through FESEM and Energy Dispersive X-ray analysis. Thermal stability of the SS PLA composites specimens was carried out through Thermo Gravimetric Analysis (TGA) and Differential Scanning Calorimeter (DSC). Crystal orientations studied through X-Ray Diffraction (XRD) showed the presence of the orthorhombic SS particulates. The properties of the composites were investigated such as tensile strength, compressive strength, exural strength, and Shore D Hardness. It was found that 20 wt.% of SS lled PLA composites has a superior tensile strength of 43.76 MPa, the compression strength of 37.94 MPa, the exural strength of 72.47 MPa, and Shore D Hardness of 80.1 SHN than pure PLA. SS particulates-lled PLA composites would be used for lowstrength applications.
