Bumper, wing board, fuel tank... More and more body parts are made of plastic. One day, will the number of plastic parts on the car exceed the metal parts? In fact, when Pierre Burelle pioneered the all-plastic brand 70 years ago, he threatened to use plastic with at least 100 of the car's interior and exterior parts.
According to Steven noyer, President of the Asia division of the all-resistant plastic ingrui (Shanghai) consulting co., LTD., the car industry now has 60 percent of its body parts made of plastic. "Fifty years ago, 100 per cent of the fuel tanks were of metal, with 72 per cent of them being plastic and 90 per cent of new models using plastic tanks."
High-density polyethylene gas tanks that blow molding are on average 20 to 30 percent heavier than conventional steel tanks, thus reducing carbon dioxide emissions. The plastic fuel tank can also meet the highest emission standards, and its own elasticity and toughness ensure higher impact resistance. This explains why 72% of cars around the world are equipped with plastic fuel tanks. Currently, the exterior panels including bumpers, wings, tail doors, spoiler, threshold and threshold trim are all made of thermoplastic plastic sheet, according to Steven noyer. Some models have 50 percent plastic plates on the outside surface.
Thermoplastic technology makes the shape design and aerodynamic components more flexible to reduce weight, reduce fuel consumption and carbon dioxide emissions. In combination with this technique, the all-resistant plastic develops a bumper calf protection system and a wing board bracket that can be used to protect the legs and head of a pedestrian when an accident occurs. In addition, composites are also a kind of plastic. Compared with steel, the body weight of the composite material used in fiberglass was 30 percent, and carbon fiber was reduced by 50 percent. Therefore, the wide application of composite materials will provide a significant reduction in vehicle weight.
