Society is increasingly demanding automobiles centered on environmental factors and fuel efficiency. Accordingly many studies have examined the use of Al, Mg and composites for lightweight automobiles. We implemented a microcellular plastic (MCP) designed for a lightweight automobile using axiomatic design. The results show that the physical properties of MCPs are most affected by the size and uniformity of the MCPs, and that a weight reduction of about 15% is possible by applying MCPs to bumper covers. In conclusion, the MCP bumper design was proved to be a decoupled design, demonstrating the applicability of MCPs to bumpers.
