Measurement of Gas Solubility and Mechanical Property for Bumper Polymer

범퍼용 수지의 gas용해도 및 물성 측정

Today, the industries use polymer material for many purpose. Specially, it is important in automobile industry because tile costs of polymer hold high proportion of the overall cost. If we reduce the weight of automobile, fuel efficiency of car is raised and cost of bumper is lower. Therefore there are many efforts to reduce of car currently. The purpose of this paper is to reduce polymer used in car bumper.
