Specific hardness? Plastic means not afraid of metal!
In people's daily lives, plastic products are everywhere. But do you think that one day, can plastic replace metal? At present, Lanxess has produced a plastic that can match the hardness of steel, and it is used in the air filter of Mercedes-Benz, which greatly saves costs, maybe in the near future. In the future, the price of Mercedes-Benz will also drop!
Lanxess has synthesized a series of high glass fiber reinforced polyamide (nylon) to replace the metal in the automotive air filter carrier. The material is expected to be applied to Mercedes-Benz auto parts in early 2017. These structural parts were made of Durethan AKV 50 H2.0 (nylon 66 containing 50% by weight of glass fibers). At present, the material is used as a plastic carrier for load-bearing structural components and was first used in the air filtration system of Mercedes-Benz vehicles.
According to Jürgen Horstmann, Account Manager at Lanxess, “This structural material has significantly reduced costs compared to previous steel structural components while meeting high dynamic strength. In addition, this structural component is lighter in weight and overall reduced. 2.9 kg, about 50% of the total weight."
The air filter, together with the fenders installed underneath it, weighs 7.9 kg. During actual operation, the weight of the assembly may increase due to dust in the air filter and dirt on the components in the wheel arch. The two filter carriers not only need to carry the weight of the assembly, but also carry high dynamic forces of the exposed components, such as vibrations caused by bumps on the construction site. Therefore, the plastic carrier must be designed to meet the same stiffness as the original steel carrier.
According to Lanxess, the plastic carrier fixes the filter directly to the carrier compared to the steel carrier, avoiding the use of the bushing and thus saving a lot of cost.
