Abstract
The appropriate compression molding parameters of the fabrication process of fiber reinforced polymer (FRP) composites materials are important to ensure the quality of composite samples. Therefore, this paper presents the determination of optimal compression molding parameters for pineapple leaf fiber (PLF)/polypropylene (PP) composite to get larger values of tensile strength through Taguchi method. The Taguchi’s L9 orthogonal array has been used as a design of experiment (DOE) while the tensile strength is assumed to be quality characteristic (responses). In order to determine optimal compression molding parameter, four parameters of compression molding, which were temperature, pressure, pre heat duration and compression duration have been analyzed. The nine samples of the composites were fabricated with 60 wt% fiber loading and 30 mm fiber length with random orientation. From the analysis of tensile test result, it was determined that the optimum compression molding parameters for PLF/PP composite which are 30 kg/cm2 for pressure, 175 °C for temperature, 6 and 4 min to pre heat and compression duration respectively and give the higher tensile strength of 34.57 MPa. From this result, it is concluded that the 60/40 wt% (PLF/PP) composite ratio with 30 mm fiber length that were fabricated with optimal compression molding parameters is the best combination to get high value of tensile strength. There are only slight differences between the predicted and experimental values, where the experimental tensile strength only decreased by 1.9% compared to the predicted value.
