Polymer Composites 29 (5): 574–578.


Fiber-reinforced polymers have received considerable attention from industry in recent years. Due to the sharp ecological damage, worldwide shortage of trees in many areas and the global demand for fibrous material, there has been growing interest in the use of recycled wood fiber as an alternative or substitute fiber source. The present study investigates the tensile, flexural, Izod impact, and water absorption behavior of Old Corrugated Container (OCC) and aspen (AS) reinforced polypropylene (PP) composites as a function of fiber content. The surface of AS and OCC fibers was modified through the use of MAPP coupling agent. From the studies it was found that mechanical properties increase with increase in fiber loading in both cases. However the addition of wood fibers resulted in a decrease in impact strength of the composites. The water absorption property at varying fiber loading were evaluated and found maximum for the OCC/PP composites. The weight gains for all specimens were less than 3.5%. Finally, the results showed the usefulness of OCC fiber as a good alternative and reinforcing agent for composite.
