Investigating the effective parameters on the mechanical properties of composites reinforced by jute fiber in the compression molding process

The development of the use of reinforced composites, as well as the increasing progress of technology in various industries, such as aerospace, biomedicine, and structures, has increased the investigation of production processes. Reinforcement of polypropylene composites with natural jute fibers is a suggested solution to protect the environment and also improve the quality of the composite. On this basis, it is necessary to study the effect of the influencing parameters on the manufacturing process of composites reinforced with jute fibers. In this research, by using existing linear regression equations, the sensitivity analysis of various parameters affecting tensile strength, flexural strength, and impact strength has been investigated. The effect of molding temperature parameters, compression pressure and compression time has been investigated using the E-fast sensitivity analysis method. Molding temperature is determined as the most influential variable in the compression molding process with the greatest impact compared to other variables. Compression pressure parameter and compression time are known as the second and third influential parameters after the mentioned parameter. The importance and influence of defined variables in the compression molding process will be considered in creating the desired quality and mechanical properties.
