Honda Motor Company, Ltd in Japan. Announced its new technology for door panel. It is introduced as the world's first application to the door panel of the vehicles. In this technology, the developers join the steel and aluminum and employed it to enable adoption of aluminum for an outer door panel.
Honda recently developed 3-technologies in that aluminum is used for the outer door panel. These are as follow:
To control thermal deformation, it includes adhesive agent with low elastic modulus and top position of the 3D Lock Seam.
To join different materials, acceptation of 3D Lock Seam structure, in which aluminum and steel panels are layered and hemmed twice.
To prevent electrical corrosion, embedding of high anticorrosive steel for the inner panel.
This new technology in Honda provides fuel efficiency economically, reducing door panel weight up to 17 percentage as compared to the steel door panel. The weight reduction at the outer side of the vehicle body focus on the point of gravity toward center of the vehicle to improve stability in vehicle guide.
Honda is making lots of efforts to reduce vehicle weight. Company is using Friction Stire Welding (FSW) technology to structure the front subframe of steel-aluminum hybrid.
