近年来由于汽车轻量化、抗冲击能力的更高要求,塑料件已成为汽车的重要部分。现在,它们在汽车上使用得越来越多,包括保险杠和翼子板、延长板、装饰件、散热器面罩、翼子板内加强板、油管、燃油箱、防石板、仪表板等。许多新型强化塑料的强度和刚性都已接近钢材,其尺寸稳定性更好,具有极强的耐腐蚀性能。目前,正在试验塑料发动机和塑料车架。塑料生产商还在设法更多地用塑料来制造车厢地板、车窗、转向轴、弹簧、车轮、轴承和其他机械零件。汽车特别是轿车上所采用的塑料品种也多种多样,包括聚乙烯、聚丙烯、ABS、聚
In recent years due to lighter cars, higher impact resistance requirements, plastic parts have become an important part of the car. They are now more and more used in automobiles, including bumpers and fenders, extension plates, trim, radiator masks, fender stiffeners, tubing, fuel tanks, stone slabs, dashboards and more. Many new reinforced plastics are close to the strength and rigidity of steel, its dimensional stability is better, with strong corrosion resistance. Currently, plastic engines and plastic frames are being tested. Plastic manufacturers are also trying to make more use of plastic to make car floor, windows, steering shafts, springs, wheels, bearings and other mechanical parts. Cars, especially cars are also used in a wide variety of plastic varieties, including polyethylene, polypropylene, ABS, poly
