There is still a long way to go from concept to mass production of "plastic cars"
light and solid design is the core of current automobile development, and it has become a trend for cars to enter the "plastic era". What's more dazzling is that the latest plastic plates can realize the whole body plasticization of cars from the skeleton to the panel
the industry believes that driving "all plastic" cars requires not only the cost of manufacturers, but also the strong support of policies and regulations. Otherwise, it will be difficult to blossom, or it will fall into an embarrassing situation like new energy vehicles
"sandwich" makes cars light and changeable.
Bayer materials technology in Germany recently announced a new research and development achievement - A-surface composite material. Its whole structure is like a "sandwich", from glass fiber reinforced polycarbonate matrix material to polyurethane foam inner core, and then to a two-component exterior decoration coating system made of polyurethane raw materials. Such a design can not only make the car lighter, but also maintain the temperature in the car, insulate it from the outside, effectively reduce the pressure of the air conditioning system, and make a great contribution to energy conservation and environmental protection
Bayer Materials Technology Asia Pacific passenger car market manager key told that if steam is also an important factor in the success of the experiment and the accuracy of the experimental results, the car manufacturer is willing, this material can be directly extended from the sunroof to the rear hatchback door, integrate many independently assembled metal parts, increase strength where needed, reduce materials and reduce weight where not needed, Greatly reduce the cost of traditional metal material assembly. In addition, this "sandwich" structure can significantly improve the impact resistance, and the price is much lower than that of carbon fiber reinforced composites
when will new technologies fly into the homes of ordinary people
"it has developed from light design to small batch production, and then to affordable and affordable driving for ordinary people. In addition to the further improvement of technology, it also requires the input of automobile manufacturers into production, as well as the encouragement of consumption policies and regulatory constraints. This rule is only applicable to the common promotion of single 1 faults." The key is to say
impact testing machine of raw materials and detection under low temperature
automobile expert Jia Xinguang also said that at present, car companies are developing various new technologies, but they are mainly focused on accessories and interior upholstery. If you want to use this new material in whole vehicles, further tests are needed. For example, developing better systems to handle raw materials, reducing costs, and how supply chains can better cooperate with each other
in addition, although electric vehicles have much higher requirements for lightweight than traditional vehicles, and the improvement of high-performance materials can greatly promote the development of electric vehicles, the interview found that this market prospect is not so optimistic
"for example, in terms of pure electric vehicles, since the state introduced the pilot policy to encourage private purchases of pure electric vehicles in 2009, up to now, some of the six pilot cities have not introduced local implementation rules, and the national pilot subsidy policy cannot be implemented." Said Yang Zhao, manager of the public relations department of BYD Automobile Sales Co., Ltd
in fact, from the perspective of environmental protection, the development of the electric vehicle industry is also related to the establishment of an inter ministerial coordination mechanism by government departments to speed up the formulation of supporting policies and measures. Experts believe that only when there is a binding force can there be motivation and force the "zero emission" electric vehicle to "accelerate"
