摘要：

Mechanical properties of jute fabrics-reinforced polypropylene composites were measured with reference to fiber loading and found highest at 45% by the weight of jute fabrics. Jute fabrics were treated with potassium permanganate in acid (oxalic acid and sulphuric acid) and alkaline (KOH) media in order to investigate the oxidizing effect on the properties of the composites. Solutions of oxalic acid, sulphuric acid, and KOH were prepared in water as 1.010.0% w/v, 0.12.0% v/v, and 1.010.0% w/v, respectively, where percentage of KMnO4 was maintained at 0.01% w/v. Among the treatments, 5.0% oxalic acid treated jute composite showed better mechanical performance. Thermogravimetric (TG/DTG) data of PP, jute fabrics and composites showed that thermal degradation temperatures of composites shifted to higher temperature regions compared to PP or jute fabrics. The treatment of jute fabrics improves thermal stability of the composites. Treated jute composites were found less degradable in soil, water and simulated weathering conditions and also found less water sensible compared to control composite (45% w/w jute fabrics). POLYM.
