Abstract: | The jute fabrics reinforced unsaturated polyester resin (jute/UPR)-based composites were prepared successfully by the hand-lay-up technique. The percentage of jute fabrics was kept constant at 40% fiber (by weight). The disaccharide percentage was also kept constant at 2% (by weight), but at this percentage the mechanical properties were lower than the untreated composites. Gamma radiation dose was varied at 0, 2.5, 5 and 7.5?kGy for jute/UPR-based composites. At 5.0?kGy gamma dose highest TS, TM and Eb were obtained. The jute/UPR-based composites were treated under 30°C, 50°C and ?18°C for the measurement of mechanical properties. At low temperature (?18°C), the highest mechanical properties were observed. The water uptake properties were measured for disaccharide-treated and disaccharide-untreated composites up to 10 days, but no water was absorbed by the composites. The soil degradation test was carried out under 12 inch soil containing at least 25% water, but no significant decrease was observed for untreated and sucrose-treated composites. For the functional group analysis, FT-IR was carried out. For the fiber matrix adhesion analysis, the scanning electron microscopic image was taken. |
