Engineering plastics have been applied to automobile components to reduce the weight of an automobile and in essence, improve fuel efficiency. In this study, the application of polycarbonate/acrylonitrile-butadiene-styrene copolymer (PC/ABS) based composite material to the car audio chassis was investigated with respect to the key properties of a car audio chassis mainly through vibration analyses, injection molding analyses and electromagnetic interference shielding effectiveness (EMI SE) tests. A PC/ABS based composite material was designed for replacing carbon steel of current car audio chassis. Before mocking up a prototype of a car audio chassis, two key factors, i.e. injection molding analyses and vibration analyses, were investigated numerically. Next, an actual injection molding of a car audio chassis based on the injection molding analysis results was carried out for various temperature conditions and two types of catapults. The optimum temperature condition and catapult type were determined by observing the distributions of composite fillers of the injection molding chassis microscopically. In addition, base excitation vibration tests were executed to obtain the vibration characteristics of the car audio chassis. Finally, EMI SE of the newly designed car audio chassis was measured to determine whether the injection molding chassis satisfied the EMI SE regulation.
Environmental regulations require the improvement of automobile fuel efficiency. This can be achieved mainly by reducing the weight of automobile components. In this study, polycarbonate/acrylonitrile-butadiene-styrene copolymer (PC/ABS) based composite mixed with glass fibers and metal fibers wa...
Fused deposition modelling (FDM) is a filament based rapid prototyping system which offers the possibility of introducing new composite material for the FDM process as long as the new material can be made in feedstock filament form. Swinburne has been undertaking extensive research in development...

A method based on an environment-cost analysis diagram is proposed here for the identification and prioritisation of product elements requiring improvement. The method involves quantification of environmental and cost aspects of assemblies, components, and materials of a product in its disposal s...
The present study is aimed to investigate micro-milling performance of thermoplastics with different parameters, namely laser beam absorptivity, latent heat of vaporization, laser power and cutting speed. The 25-W CO2 (CW) laser engraving machine is used for the investigation. In total 50 differe...
We report the development of a novel light-weight Al (520) alloy-based composite reinforced with particles of a Cu-based (Cu54Zr36Ti10) metallic glass by mechanical milling followed by induction heated sintering. The consolidation of the composite is performed at a temperature in the super-cooled...
Reflection type photoelastic experiment can be used more effectively than a transmission type photoelastic experiment especially in industrial fields. Moreover, composite materials have been widely used in engineering applications and structures because of their outstanding advantages which indiv...
The main aim of this paper is a development of the semi-analytical probabilistic version of the finite element method (FEM) related to the homogenization problem. This approach is based on the global version of the response function method and symbolic integral calculation of basic probabilistic ...
This paper surveys the most important developments in resin-based dental composites and focuses on the deficits (e.g. polymerization shrinkage) and strengths of the materials and their clinical implications. Moreover, differences between composite categories, such as hybrid, nanohybrid, microfill...
