According to a survey report conducted by the American Automotive Research Annual Management Symposium, the current part of the automotive industry that tends to lose weight is the powertrain. High-performance engineering plastics can help the engine to reduce weight and replace metal materials to meet the needs of environmental protection and weight reduction.
The survey, co-sponsored by DuPont and Wards Auto, shows that 24% of respondents said that engine and transmission systems are the primary weight-reduction parts of their car manufacturing process; 12% of respondents believe that car chassis The use of lightweight design is imperative; the proportion of respondents who agree to slim down the body and interior of the car is 11% and 9% respectively.
Jeff Sternberg, DuPont's Automotive Technology Business Unit, said that successful cases of weight reduction in other parts of the car prompted component manufacturers to turn their attention to the powertrain. The material consumption of the parts and components in this part is very large. This is a great opportunity for lightweight plastics for vehicles.
At the seminar, GM materials engineers said that when choosing plastics for vehicles, they are more concerned about the high temperature and corrosion resistance of the materials. Currently, plastics and their composites are widely used in general-purpose vehicle power systems. There is a high-performance engineering plastic in the Fleet Cruz engine parts.
In order to reduce the weight of the car, in recent years we have begun to use a variety of different plastics such as PA, PPS (polyphenylene sulfide), PEEK (polyether ether ketone) to replace metal materials. These plastics are excellent in high temperature and corrosion resistance. And our material suppliers are constantly improving the performance of their products and actively developing some new environmentally friendly plastics. Derek Ewing, GM's business unit engineer, said.
