Investigation of Physical and Mechanical Properties of Old Magazine Recycled Fiber and Glass Fiber- Polypropylene Hybrid Composite

In this research, Old Magazine (OMG) recycled fiber and glass fiber (GF) were mixed at different levels of 10%, 20%, 30% and 40% (based on weight) with two levels of 50% and 60% Polypropylene (PP) and then the produced composites evaluated compared to those from net Polypropylene. On the basis of obtained results from normalization equations in different treatments done, two treatments has been selected at a point of the better physical and mechanical properties and then chemically modified by maleic anhydride Polypropylene (MAPP) at two levels of 0 and 4%. Achieved results showed that treatments including the ratios 20:20:60 and also 20:30:50 (GF, OMG, PP, respectively) were resulted in the composites with improved physical and mechanical properties. Utilizing MAPP caused to improve the mechanical properties of composites and decrease of thickness swelling, water absorption in two optimum treatments before determined. Scanning electron microscopy results showed that in the composites contain of MAPP, Fibers were desirably compounded with Polypropylene.
