Physical and Mechanical Characterization of Jute Fiber Reinforced Unsaturated Polyester Resin (UPR) Composites

Abstract :
Jute fiber reinforced unsaturated polyester resin (UPR) composites were fabricated by hand lay-up technique where cobalt octoate is used as an accelerator. This work presented the UPR jute mat composite’s behaviour towards different moulding pressure and duration of moulding in mechanical and thermal properties and trying to investigate the possibility to use as a good source of natural fiber composite as well. This study reveals that with the increase of moulding load mechanical properties such as flexural strength, ultimate tensile strength (UTS), elongation is increased but with excessive moulding pressure the UPR is comes out from the composite and increases the % of fiber content which causes reduction the values of mechanical properties. We also tried to optimize the moulding load and time of pressing. Our result shows that 180KN pressure for 240 minutes gives the best mechanical and physical properties.
