Abstract
Molding process parameters decide the quality of the composite. Optimization of Molding Process Parameter will improve the quality of the composite. In this paper, molding process parameter optimization is carried out for molding Jute Reinforced Polylactic Acid polymeric Composite in the compression molding machine. Response surface methodology with the composite design is used. Curing temperature, curing time, pressure and mold temperature are taken as an input factor and tensile strength, hardness and impact strength are taken as a response. The analysis is evident that that smaller changes in the mold temperature will reduce the mechanical properties of the mold. With molding process parameters of 190 o C curing temperature, 1300 seconds curing time, 80 bar pressure and 190 o C mold temperature gives composite with significantly improved mechanical properties.
