As the competition of the automotive industry has risen. efficient plastic materials are now being used to reduce weight. cost. and noise. These apply to underhood parts as well as interior/exterior parts in automobile. The representative plastic example of replacing aluminum materials in underhood parts is an air intake manifold which is to be used nylon resins as substitute materials. As nylon air intake manifolds continue to grow in automotive applications. trends in assembly techniques and system integration will affect material performance requirements and final material selection. Keeping these trends in mind. this paper will examine several nylon materials in relation to material requirements( heat resistance. chemical resistance. weld ability . burst pressure test etc )

Incoming environmental legislation is expected to impose recycling activities on automotive industry. Disassembly of end of life vehicle is needed in order to make recycling economically viable in the current .state of the art of reprocessing technology. thus avoiding the future high disposal costs. this study gives an overview of disassembly research at research centers and automotive companies. pointing out ongoing topics and trends for future activities. Among them. major attention has been paid to basic technological development. product design. process design and system design. A result of the study is that futher developments on disassemble of existing products is needed allow future products to be designed with recycling considerations in minds.

In this paper. the outline of LCA(Life Cycle Assessment) was introduced and the trend of LCA was reviewed. The Automobile manufactures in Europe. America and .Japan have already conducted the LCA in components of vehicle and complete vehicle. This paper contained the content of LCA conduct. Daewoo Motor Company also conduct the LCA of Bumper and Camcover by material difference. The Automobile manufacturers will be able to use the LCA as tool to evaluate the environmentally friendlier product.

A vehicle contributes to current environmental situations such as air pollution and wastes. In recent years there have been increasing demands for car manufacturers to solve these problems. In order to respond to these claims, much researches or actions at the car manufacturers are already underway.<br/> This paper summerizes the current trends of environmental pressures : environmental regulation, environmental standard, the relation between environment and trade. In addition, this paper tries to propose some methods to respond to these issues.<br/>

The selection of the plastics material for the automotive parts is very important step because it should be considered the all factors from the weight down. cost reduction. quality improvement at the application step to the recyclability at the disposal step. Nowadays. the material trend of the automotive parts is enlarging the amount of the environment-friendly material and using the environmentally harzadous materials such as PVC is being restricted gradually. So. in this study. some automotive parts are selected. and PP/SBS blend material is developed with considering the requirements for the each part as PVC replacing material.
