Abstract
Waste red mud (RM) serves as a low-cost and sustainable filler material in a polypropylene (PP) matrix. This study investigate the effects of different red mud contents on the dynamic mechanical and thermal properties of polypropylene-red mud (RM-PP) composites where red mud levels range from 0% to 40% (based on weight percentage). Fourier Transform Infrared Spectroscopy (FTIR) was conducted for verifying the presence of both polypropylene and red mud in composite samples. The dispersion of red mud within the polypropylene matrix was examined through Scanning Electron Microscopy (SEM). X-ray Diffraction (XRD) analysis was performed to evaluate the crystalline structure of the composites. Thermogravimetric Analysis (TGA) assessed the thermal stability of the polypropylene-red mud composites, specifically determining their resistance to thermal degradation; notably, the composite containing 40% red mud exhibited excellent thermal stability. Differential Scanning Calorimetry (DSC) was utilized to compare the melting temperatures (Tm) of the composites, showing that the melting temperatures of the polypropylene matrix increased following the incorporation of red mud, indicating strong interactions between polypropylene and red mud. Additionally, Dynamic Mechanical Analysis (DMA) results demonstrated a decrease in storage modulus with increasing red mud content, while XRD findings confirmed that crystallinity was increased with red mud concentration.
Keywords: Polypropylene (PP), Red mud (RM), Polypropylene-red mud (RM-PP) composites, Thermal behavior, Sorage modulus.
