The Innovators of the Auto Industry: Enhancing Safety and Performance through Optimized Sheet Metal Materials
Date：2024-03-05 11:41
The unending quest for safety and performance makes the automobile industry what it is today. As an authority on automotive materials engineering, I have seen up close how the evolution of sheet metal materials has changed both the design and the manufacturing processes of vehicles. In this article, we will look at the kinds of advancements in sheet metal materials that are moving the auto industry forward and give some concrete (and successful) examples of these advancements from the real world.
The ever-growing need for safer and more fuel-efficient vehicles has caused the automotive industry to pivot toward using advanced high-strength steel (AHSS) alloys. These materials afford a superior strength-to-weight ratio, yielding lightweight, strong structural components that deliver even better vehicle performance. Lightweighting is not just about fuel economy, and it is definitely not about diminished vehicle births. It is about driving the vehicle with better overall acceleration, deceleration, and handling—vehicle dynamics that directly involve you and me. Vehicle dynamics that, let's acknowledge it, we pay good money to experience.
An excellent instance of material optimization is Ford's switch to military-grade aluminum in their F-series trucks. Starting with the 2015 F-150, Ford introduced aluminum body panels that reduced the truck's weight by nearly 700 pounds without sacrificing durability. This revolutionary move in the truck segment certainly redefined what is possible regarding fuel economy and performance.
Attention is not exclusively being paid to traditional metals; composite materials are now gaining ground in the auto industry. One of the most exciting developments in this area is the use of carbon fiber-reinforced polymers (CFRPs), which are employed in everything from body panels to chassis components in a number of today's sports cars. They are lightweight, but more importantly, they are very rigid. In fact, with regard to weight and rigidity, they are unmatched by any other material. And their use in the auto industry is a direct result of their use in the aerospace industry.
The use of carbon fiber in cars is championed by BMW. When it came to producing electric vehicles, the automaker saw the opportunity to rethink the EV, bringing new forms of efficiency and safety to this otherwise mundane auto body style. The BMW i3, introduced in 2013, takes full advantage of carbon fiber and, as a result, has the lowest mass of any electric vehicle. And get this: the only thing occupying more space than the battery pack in the i3 is the passenger cell, which is a first in that it is completely made of carbon fiber.
The processing of materials is another area where technology is advancing. Hydroforming, hot stamping, and tailored rolled blanks are changing how sheet metal is worked in ways that are beginning to allow the production of structural parts that meet the letter of the law in terms of safety without wasting materials and, hence, without incurring penalties in terms of the weight and volume those parts take up.
Hydroformed metal parts are a tremendous asset to sports cars, well-suited to the performance and appearance required of these vehicles. The Chevrolet Corvette, in particular, stands out among hydroformed cars, having used this technique since the C5 generation of the early 2000s. Hydroforming produces not only lightweight but also rigid parts—two essential attributes for a car's frame. The C5, C6, C7, and now the C8 have all benefited from a single-piece main frame to which the suspension is mounted, an enormous construction that swallows up both sides of the car and runs from the front through the rear.
Sheet metal material innovation is pushing the automotive sector inexorably toward vehicle efficiency, driving enjoyment, and, most importantly, occupant safety. As industry professionals, we understand that the essence of these developments comes from continued research and dedicated development in the scientific discipline of material formulation and processing. Yet our embrace of those fresh ideas is no guarantee of arriving at the good-natured, problem-identified solutions that future vehicles demand. Staying ahead of the demands made by consumers and regulators is no easy task.
