In the field of lightweight materials, light metal, high-strength steel, and plastic parts can be used instead of metal parts (plastic-made steel) to achieve weight reduction.
The plastic parts have a low density. Generally, the specific gravity of the plastic is between 0.9 and 1.5, and the specific gravity of the fiber reinforced composite material does not exceed 2.0. The specific gravity of the metal material is 7.6 for A3 steel, 8.4 for brass, and 2.7 for aluminum. This makes plastic materials the preferred material for lightweight vehicles. Among the many weight-reduction schemes, “plastic-based steel” is in a rapid growth period with great development potential and obvious advantages.
Plastic-based steel technology, mainly using PP (polypropylene), PC (polycarbonate) and ABS (acrylonitrile-butadiene-styrene copolymer) and other engineering plastics, replacing traditional steel, as a body parts, making The weight of the vehicle is reduced to 1/4-1/8 of the original weight, which makes the car lighter and reduces the fuel consumption of the car.
