Abstract
This study focuses on the use of Alibizia Lebbeck Benth pod particles (ALBp) as reinforcement
on low density polyethylene (LDPE). Composites were processed via casting where 408 and150
µm ALBp where used in reinforcing LDPE. Samples were subjected to Fourier Transform
Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), X-Ray Diffraction
(XRD), Differential Scanning Calorimetry (DSC). Thermogravimetry Analysis (TGA) impact
strength and tensile characterizations. Composites showed improved thermal stability and
crystallinity compared to unreinforced LDPE. Tensile strength (UTS) of composite increased
by 331% as it improved from 0.36MPa for unreinforced LDPE to 1.55MPa using ALBp of
150µm. Additional C=C and C-O-C groups observed on the composite’s spectrum could be
responsible for the improvement in mechanical properties. Reinforcing LDPE with larger
ALBp (408µm) culminated in the formation of gaps and voids in the composite
