A new era!

This is the conclusion given by Zhou Jingming for the future application of carbon fiber materials in the automotive field.

Limited by the influence of technology and cost and other factors, at present, Tianming Group is only in the all-aluminum body of a small piece of back plate using carbon fiber materials, and has not reached the degree of popularization, with the progress of technology in the future, carbon fiber will appear more and more in the car, not only the body, the wheel, and even the engine shell, can use carbon fiber materials to achieve the goal of lightweight.

By that time, the mass of the whole vehicle will be lighter than ever before.

As early as last year, Tianming Group has been at the request of Zhou Jingming, and the former Runzhou Institute of Technology, now renamed the Agricultural Machinery College of Jiangsu Provincial University of Technology, jointly established the Institute of Automotive Materials, funded by Tianming Group, research and development of various new automotive materials, carbon fiber materials are Zhou Jingming's name to focus on the research area.

With the help of scientific research institutes, Zhou Jingming is confident that Tianming Group will be in a leading position in the research and development of carbon fiber materials.

Although the reporters at the scene didn't quite understand the meaning of carbon fiber materials, since Zhou Jingming valued it so much, it naturally made sense, so more than a dozen cameras suddenly pointed at the carbon fiber plate on the body.

"In addition to making great improvements in the body materials, the connection methods of various material joints are also very testing our technological level, in order to be able to meet certain standards, we have a mix of cold connection methods such as crimping connection, adhesive edge banding technology, riveting, etc., or using the latest laser welding, in terms of body quality assurance, each body has more than 2,000 inspection points......

In the following time, Zhou Jingming gave a detailed introduction to the rest of the innovations, and the crowd of onlookers became more and more interested.

People are always curious about the unknown.

"Mr. Zhou, about the all-aluminum body, I still have two questions, one is the safety issue, many consumers believe that the all-aluminum body reduces the quality of the vehicle at the same time, but also makes the safety performance of the vehicle greatly reduced, Tianming Group has always paid attention to the safety performance of the vehicle, this time your company's new car adopts the all-aluminum body, will the safety performance of the vehicle be sacrificed?"

After explaining how to connect, a German journalist asked in broken English.

"I think this question is very valuable, and the safety performance of the all-aluminum body is also a point I want to clarify with everyone, and it is also the point that everyone misunderstands the most about the all-aluminum body. ”

For a long time, the biggest misunderstanding of many people about the all-aluminum body is that the all-aluminum body is very unsafe. Even Audi's use of all-aluminum bodies in production models has not been able to dispel everyone's doubts.

"First of all, I want to correct that there is no causal relationship between the safety of the car and the quality of the whole vehicle, compared with the impact of the weight of the body, the structural stiffness of the key parts of the body and the overall body frame design can better reflect the safety level of a car, and the lightweight of the vehicle will not be exchanged for sacrificing safety performance. ”

Zhou Jingming paused, and then continued, "Our Tianming Group has always been known for its safety performance, and this time the all-aluminum body will only strengthen the safety performance. Please see ......"

At Zhou Jingming's suggestion, the multimedia screen behind the exhibition area suddenly lit up, and then the three-dimensional design of the entire all-aluminum body was displayed in front of everyone.

"As the most critical part of the whole body, we have adopted different strength designs for the upper and lower parts of the B-pillar, and the cross-sectional thickness of the entire B-pillar is also in the form of variable cross-sections, and different thicknesses are made by rolling and thermoforming processes. ”

"The different thickness distribution of the B-pillar and the different cooling times of the upper and lower parts make the upper part of the B-pillar stronger, and the lower part is slightly weaker, when the vehicle has a side impact, the upper part of the B-pillar ensures the integrity of the cabin, and the lower part can slow down the impact of the collision, so that the occupants in the car are safer. ”

In the video on the screen, the entire B-pillar deformation process after the side impact is even simulated, and anyone who knows a little about car safety can see that from the simulation effect alone, the safety performance of this all-aluminum body will definitely not be worse than the previous cars!

“…… In addition, the body is made of hot-formed ultra-high-strength steel at the location of the engine firewall and in front of the front passengers, so that the engine does not invade the interior of the cabin in the event of a frontal impact...... The engine compartment bracket is made of cast magnesium alloy for excellent stiffness...... In terms of structural design, a large number of annular structures are adopted, which greatly improves the torsional resistance and increases the rigidity of the whole vehicle......"

With the assistance of Zhou Jingming's explanation and the video behind him, everyone also has a great understanding of the safety of this all-aluminum body.

"If it's really like what he said, then our misunderstanding of the all-aluminum body is really not small. ”

"I'm afraid that the princess sells melons and boasts about herself. ”

"It's a great feat to be able to achieve such a high level of safety while achieving the goal of lightweighting. ”

For so many people's discussions, Zhou Jingming just smiled, "The specific safety performance, we will be announced after the completion of the new car research and development, the results of the crash test will be announced simultaneously, please wait and see, as for the second question of this reporter friend, I guess it should be maintenance." ”

"I have to admit that the maintenance of the all-aluminum body, to a certain extent, is indeed more difficult than the ordinary body, which is due to his unique design, we have carried out a lot of structural optimization on the all-aluminum body, greatly improving the convenience and feasibility of maintenance, from this point of view, the all-aluminum body is not more expensive than the ordinary steel body maintenance, and with the deepening of our research, it will not be long before the all-aluminum body will be like the ordinary body, into thousands of households. ”

…………

In the next time, Zhou Jingming answered a few reporters' questions, and then returned to the lounge accompanied by the staff, and after Zhou Jingming's publicity, everyone paid more and more attention to the all-aluminum body of Tianming Group.

However, for ordinary tourists, the all-aluminum body is mysterious, but the ornamentation itself is not high, but many reporters and professional evaluators flocked over, they have a hunch that Tianming Group's all-aluminum body will definitely cause a sensation in the international automobile industry in the future.

"I didn't see it, Jingming, the incitement ability is quite strong, if you want me to say that you come to the sales company. Seeing more and more people gathered around the booth with an all-aluminum body, Xu Weidong couldn't help but quip.

"What is the ability to incite, am I convinced people with reason?" Zhou Jingming replied angrily, and then, Zhou Jingming looked at the crowded exhibition hall again, "I have said everything that should be said, it depends on how these media react." ”
