AB  - Polypropylene (PP) composites reinforced using a novel plant fiber, sunflower 
      hull sanding dust (SHSD), were prepared using a twin-screw extruder. Thermal and 
      mechanical properties of the SHSD/PP composites were characterized and compared 
      to an organically modified clay (organo-clay)/PP composite. Differential scanning 
      calorimetry (DSC) analysis showed that the crystallization temperature and the 
      degree of crystallinity of PP exhibited changes with addition of SHSD and 
      organo-clay. Mechanical properties of the PP were enhanced with the addition of 
      SHSDs. Both the flexural strength and flexural modulus of the PP composites 
      containing 5% (w/w) SHSD were comparable to that of the 5% (w/w) organo-clay 
      reinforced PP. Scanning electron microscope (SEM) observation showed that no 
      obvious agglomeration of SHSD existed in the PP matrix. Compared to the neat PP 
      and organo-clay/PP, the SHSD/PP composites exhibited a relatively decreasing rate 
      of thermal degradation with increase in temperature. Experimental results suggest 
      that SHSD, as a sunflower processing byproduct, may find promising applications 
      in composite materials.
