(134b) Effects of Treatments On the Mechanical Properties of Cellulose Reinforced Composites From Recycled Jute Woven Cloth

Natural fiber reinforced composites were prepared from unsaturated polyester and recycle coffee bag (jute plain woven cloth). It is found that the higher moduli of composites were obtained by the adding of jute compared to the neat resin based on the results of tensile, flexure and Izod impact tests. However from the observation on the fracture surface of the tested specimens, it is found that the interface property between jute fiber and polymer seems weak. Therefore, at current study, in particularly, some treatments were carried out on the jute woven cloth before impregnation with polymer. The effects of the treatments on the mechanical properties of the composites were discussed compared to the natural ones.
