Abstract: 

In this study, the physical and mechanical properties of polypropylene composites reinforced with alkaline sulfite-anthraquinone, soda-anthraquinone and monoethanolamine-anthraquinone and chemical mechanical produced from non-extrated and pre-extracted bagasse with hot water were studied. MAPP coupling agent (3%) was added and the performance of pretreated and unpretreated bagasse composites were compared. The ratio of the polypropylene and reinforcement material (pulp) was considered at 50/50 (w/w). The results showed that the pulping process has a significant effect on all physical and mechanical properties of produced composites. In general, composites containing chemical pulps showed greater dimensional stability and mechanical strengths but lower water absorption than that of mechanical pulp. Composites containing treated fibers with alkaline sulfite-anthraquinone and soda pulp had the highest mechanical properties and dimensional stability. Composites made from fibers in which hemicelluloses were extracted and then were treated with chemical pulping processes had the highest mechanical strength and dimensional stability among all of samples. The highest mechanical strengths and dimensional stability were observed in composites which were reinforced with treated fibers compared with control samples containing untreated bagasse fibers. In general, the results showed the superior physical and mechanical characteristics for pulp - plastic composites compared with wood flour plastic composites.
