Vehicle weight reduction becomes important at the view point of fuel efficiency improvement and CO2 reduction in India also as well as developed countries.
With this background, High tensile and Super high tensile steel application has become increasing.
Similarly, weight reduction of big plastic parts like bumper face is one of the most important items, so Honda has developed Thin-wall and light weight bumper face.
In the development of light weight bumper, rigidity, impact strength and flowability which are main requirement are contradictory property. It is necessary to develop new material to achieve this technical concern.
Moreover, we verified part shape and thickness optimization to achieve part requirement.
Established high property material and part manufacturing technology were applied for current CITY firstly, and it has been expanded to other models sequentially to contribute weight reduction for Honda vehicles.
In this report, we report the analysis and verification result example of high rigidity and light weight bumper material development in India.
