Effects of maleated polypropylene and cellulose content on mechanical and thermal properties of recycled polypropylene/microcrystalline cellulose (rPP/MCC) composites /
Polypropylene (PP) is one of the most used thermoplastic materials. However, the recycled PP (rPP) exhibits degradation in its mechanical and thermal properties as compared to the virgin PP due to high temperature during processing. In this research microcrystalline cellulose (MCC) fiber was added t...

| 520 | |a Polypropylene (PP) is one of the most used thermoplastic materials. However, the recycled PP (rPP) exhibits degradation in its mechanical and thermal properties as compared to the virgin PP due to high temperature during processing. In this research microcrystalline cellulose (MCC) fiber was added to enhance the properties of rPP. The maleic anhydride grafted polypropylene (MAPP) was also used as a coupling agent to improve the interfacial adhesion between MCC fibers and rPP matrix. The rPP/MCC composites were compounded with twin screw extruder and then injected molded. Initially the effect of various MAPP (2, 3 and 5 wt%) loadings were evaluated with mechanical and thermal tests. Samples with 3wt% of MAPP showed optimum mechanical results while the thermal stability shifter to the higher temperature. Next the contents of MCC fiber in rPP composites were varied from 2, 5, 10, 20, 40 and 50 wt% along with 3 wt% of MAPP. The samples without MAPP were also compared. It is found that without MAPP the tensile strength of rPP composites decreased along with MCC loadings. The impact strength exhibited higher results than neat rPP at low MCC loading but then decreased at high MCC loadings. All the mechanical properties showed improvement in the presence MAPP, particularly the tensile modulus. Nevertheless, higher loadings of MCC caused degradation in thermal stability. Good adhesion between the MCC fibers and rPP matrix was evident from FESEM morphology. Fracture surface analysis suggest that both samples with and without MAPP changed from ductile to quasi-brittle mode with increasing MCC loadings. | ||
