This investigation was carried out to evaluate the possibility of utilization of recycled
newspaper fibers as reinforcer in unsaturated polyester to be used in the making of Wood FiberlPolyester Composite (WFPC). The objectives of the study were: to compare reinforced with unreinforced polyester; to study the effect of Silan as a coupling agent, and percent by weight of fibers, as reinforcer, on the Properties of WFPC.
Six treatments were employed, one of which was pure polyester and among the rest, four contained 5, 10, 15 and 20 percent Silan - coated fibers while the last one carried 10 percent uncoated fiber. All treatments were carried out using only chemical processes and moulding lnethods without application of any external heat. The results of mechanical tests revealed improvement of polyester properties when reinforced by recycled newspaper fibers. Positive effect of Silan on WFPC became evident too.
