This study investigates the effect of adding the nanoclay particles on the mechanical properties of
polypropylene-made cellulose composite. Based-on-polypropylene composites are mixed with the particles of wheat
stalk flour with the dimensional size (mesh 80), nanoclay at three different levels (0, 2 and 4) per hundred
compounds (phc) and also with Maleic Anhydride-grafted Polypropylene (MAPP) as compatibilizer by Dr. Colin
machine at 180°C and 60 rpm and the standard test samples were made by injection molding method. Then the
mechanical properties such as the tensile strength, flexural strength and impact strength were measured. Finally, the
cellulose composite was examined by the X-Ray Diffraction method (XRD) in order to study the structure and
function of nanoclay particles and particles of wheat stalk flour with dimension 80 mesh. The results of mechanical
test indicate that with an increase in the nanoclay amount up to the level 2 phc, the tensile and flexural strengths and
tensile and flexural modulus of composite will be increased. However, these strengths will be decreased by
increasing the amount of nanoclay to the level 4 phc. Moreover, the impact strength of composite is decreased by
increasing the amount of nanoclay. Survey, conducted by the transmission X-ray diffraction on the nanocomposites
indicates that the samples containing 2 phc nanoclay in the combination with the polymer have reached the
intercalated structures. Furthermore, the samples with 4 phc nanoclay have shown the intercalated-flocculated
structures. In general, the results showed that the best combination of materials for making the composite contained
2 phc nanoclay in terms of mechanical properties.
