Interaction and Optimization of Machine Parameter towards Mechanical Properties of New Composed Composite: Dynaglass PPG3637

Abstract

This study reveals the interaction and optimization of machine parameter towards mechanical properties of new composed composite. The new composed composite is polypropylene reinforced with fiber glass composite. Injection molding machine is utilized in this study. The processing parameters involved on the experimental are melting temperature (MeT) (250°C – 280°C, injection pressure (IP) (22 MPa – 28 MPa) and cooling time (Ct) (60s – 90s). The optimum processing parameters value that gives highest tensile strength, highest tensile modulus and shortest elongation were studied. From the result analysis, it is found that the injection pressure is the most significant parameter that affected tensile strength and percentage of elongation. Meanwhile, melting temperature shows the most significant parameter affected on the tensile modulus. The optimum parameters affected the tensile strength are 250°C for MeT, 22 MPa for IP and 77.97s for Ct. Further, optimum parameters affected the tensile modulus are 262.4°C for MeT, 27.0 MPa for IP and 60s for Ct. Finally, optimum parameters affected the percentage of elongation are 250°C for MeT, 28 MPa for IP and 90s for Ct.
