Trend toward weight reduction of automobile body in Japan 2000-05-0240
With society demanding automobiles that provide higher fuel
efficiency, safety of occupants in collisions and that at the end
of their service life can be recycled with low environmental
impact, the steel industry is tackling the needs of the automobile
industry by developing ever-higher performance steel materials and
simulation technologies that can demonstrate the performance of
steel materials at the development stage without the need for
costly prototype testing. In this paper, weight reduction of
automobile body in Japan will be discussed.
The main items will be as follows: (1) Development of Automobile
Steel Sheets, (2) Materials for Automobile Bodies, (3) Materials
and Technologies (Tailored Blanks, Hydroforming and Locally
Quenching) for Reducing the Weight of Panels and Reinforcing
members, (4) Future Prospects.
