This paper is to investigate the tensile strength of new palm oil based wax/HDPE/Palm oil fiber blends was investigated by using 2³ factorial design experiment. The palm oil based wax exhibits the potential of replacing the existing industrial blue wax which apply in prototype making. The industrial blue wax is widely used to produce part prototypes from the machining process. Hard and self-lubricating are the factors which this material are has been choosing in the industries and educational purposes. The. Hardness results has been taken to compare with the industrial blue wax. The result shows that the tensile strength of new palm oil based wax/HDPE/Palm oil fiber blend was obtained is higher compared to the existing industrial blue wax. However, since the cost of this new palm oil based wax is lower, it will be an attractive option to replace the existing industrial blue wax for prototype application. [ABSTRACT FROM AUTHOR]

This paper is to find the possibility of developing a new blend composite in order to produce a prototype for engineering application. The new palm oil based wax is a waste material produced from palm oil refining process. Recent prototyping activity, industrial blue wax is normally used to produce part prototypes from the machining process. Hence, the tensile strength of new palm oil based wax/LLDPE/Palm oil fiber blends was investigated. The result shows that the tensile strength of new palm oil based wax/LLDPE/Palm oil fiber blend was obtained is higher compared to the existing industrial blue wax. Machinability study covered surface roughness, chip formation characteristic, dimensional consistency and cutting tool wear. The higher tensile strength of the blend was selected to preceed for the machining test. The comparison results between LLDPE/palm oil based wax/ Palm oil fiber blends and Industrial blue wax were recorded. However, since the cost of this new palm oil based wax is lower, it will be an attractive option to replace the existing industrial blue wax for prototype application. [ABSTRACT FROM AUTHOR]

This research was conducted to study the thermal stability of cooking palm oil when subjected to heat in an attempt to study its ability as viscosity index improver. Four samples of mixture of Shell Rimula X SAE 40 engine oil and cooking oil at different compositions were heated over a three-hour cooking period, to provide a time course of changes in mixed oil temperature, vapor temperature, and mass of mixed oil. The significant data change of the temperature and mass over time proposes that the thermally stable cooking oil is a suitable viscosity index improver. The effect of heat on mixed oil temperature, vapor temperature, and mass are evaluated to analyze the reliability of cooking oil as Viscosity Index Improvement (VII) based on thermal stability. The Shell Rimula X SAE 40, after being added with fresh cooking palm oil, is expected to exhibit a stable viscosity-temperature curve. [ABSTRACT FROM AUTHOR]
