Honda is again paving the way to create better technology and better cars in the future. Strike that. Honda is paving the way to create better cars starting in March.
Honda engineers developed a way to create a steel-aluminum door panel, including how to join the two materials, technology to prevent corrosion, and technology to control thermal deformation. Traditionally, door panels are made of strictly steel; by using aluminum for part of the door, Honda reduced the door weight by 17 percent.
Naturally, any amount the car weight is decreased will help with Honda’s industry-leading gas mileage. And, no doubt, Honda engineers have managed to decrease the weight without compromising the integrity of the vehicle or safety of the passengers.
Here’s what it took to make this new technology work according to this article:
- “Technology to join dissimilar materials: adoption of “3D Lock Seam” structure, where the steel panel and aluminum panel are layered and hemmed together twice (see figure 1).
- Technology to prevent electrical corrosion: adoption of highly anti-corrosive steel for the inner panel and a new form that assures the complete filling of the gap with adhesive agent (see figure 2).
- Technology to control thermal deformation: adoption of adhesive agent with low- elastic modulus and optimized position of the 3D Lock Seam.”
Leave it to Honda to innovate some of the latest and greatest technologies!
