Abstract

In this work, the effect of processing temperature of polypropylene (PP) on the viscosity and the melt flow index (MFI) is studied towards the best fabrication of PP/kenaf composites. PP with MFI grade 41 and as density value of 0.95 g/cm3 is used as a raw material. The compression moulding machine is utilized to produce the moulded samples from PP pallets. The viscosity and the MFI tests have been selected as criteria to determine an optimum processing temperature. As optimum temperature 230°C has been found.

Kurzfassung

In der diesem Beitrag zugrunde liegenden Studie wurde die Wirkung der Prozesstemperatur für Polypropylen auf die Vis – kosität und den Schmelzindex untersucht, um die beste Herstellung von Polypropylen-Kenaf-Kompositmaterialien zu ermöglichen. Poly propylen mit einem Schmelzindex von 41 und einer Dichte von 095 g/cm3 wurde dabei als Rohmaterial verwendet. Die Formpressmaschine wurde verwendet, um Formstücke aus dem Polypropylen-Granulat herzustellen. Die Viskosität und der Schmelzindex wurden als Kriterien gewählt, um die optimale Prozesstemperatur zu bestimmen. Als optimal Temperatur stellte sich dabei 230°C heraus.


Bernard Maringgal, born 1984, obtained his degree in Bachelor of Engineering (Biological and Agricultural) in 2007 at the Universiti Putra Malaysia. Now he is master student at the Department of Biological and Agricultural Engineering, Faculty of Engineering, Universiti Putra Malaysia.

Aidy Ali is Associate Professor for Mecha – nical Engineering at the University Putra Malaysia (UPM). He received his first degree in Mechanical Engineering from the University Putra Malaysia, 1999, then continued studies at the University Kebangsaan Malaysia (UKM) in Manufacturing System Engineering, leading to the Master degree. He is working on simulating crack propagation of elastic plastic material under mixed mode loading conditions.

He was awarded with a M. Eng. degree in 2002. After that, his pursued his Ph.D degree in 2003 by performing research on improving the fatigue life of aircraft components at the Sheffield University, UK. He was awarded a Ph.D degree in December 2005. His expertise is related to mechanical fatigue and fracture of metallic materials, failure assessment, failure prevention analysis, reliability engineering, and crash analysis.
