Chapter 279 Radial Tires (Fourth update, please subscribe)

Radial, wire tires.

Although he had an idea, Li Yian really didn't understand what radial tires were.

After all, he's really not a professional.

But from amateur to professional, all you need is... a system.

The system requires certain conditions to be activated.

Such as learning opportunities.

Whatever you say, do it as soon as you say it. Don't put it off, because things will just be put off again and again. So no matter what you do, the key is not to think about it, but to do it. This is the truth that Li Yian summed up as a laborer.

Because it was the weekend, he didn't want to disturb others, so he decided to go to the library to find some books to see if there were any books related to tires in the library, which might give him some inspiration.

To be precise, it activates the learning function of the system.

"Calculation and Design of Automobile Tires"

"Tire Design Technology"

"Tire Design Theory and Methods"

I have to say that this library, which was moved from Germany, has a very complete collection of books, although most of the books are in German.

After selecting a few books from the science area, Li Yian planned to study them carefully.

To be honest, judging from the current situation in Borneo, the first pot of gold should indeed be tires. There is no way. This is the resource advantage. Borneo's rubber production accounts for 60% of the world's total production.

The industry most suitable for Borneo at the moment is the tire manufacturing industry, and Li Yi'an also planned this. Even when he was still in North Africa, he had already ordered equipment for tire production from the United States. When the troops arrived in Zamboanga, the annual output was 100 million. The tire production equipment arrived in Zamboanga. Why did the United States respond so quickly? Because tires are an urgent need. If tires can be produced in Borneo, they can be supplied to the U.S. military and allied forces in the Pacific nearby.

For this reason, the United States not only provided a loan for the tire factory in the Lend-Lease Act, but the equipment was provided by the tire giant Goodyear, and even the factory drawings were provided by Goodyear. Not only were installation engineers sent to assist in building the factory, but also production engineers were sent to guide production.

In short, people are surprisingly generous when they have a plan.

Holding a stack of books, Li Yian went straight to the reading area, opened the books and started reading. As soon as I opened the book, the system popped up a series of prompts.

[Discovered in the location "Calculation and Design of Automobile Tires", you can learn the skill "Calculation and Design of Automobile Tires". Do you want to learn it? 】

Sure enough, System Dad is still as awesome as before. As long as you get the book, you can learn skills!

Li Yian quickly chose yes, and knowledge of the skills quickly poured into his mind.

Level 1 tire design skills not only allow Li Yian to understand the knowledge of tire design, but also the design characteristics and various rules of various tires.

"There are radial tires."

The knowledge in his mind made Li Yian's lips curl up. He knew that the system could "smuggle technology".

The technical level of the current system is roughly equivalent to that of the early 1950s. Although it is only slightly imitated, for Li Yian, this is definitely a treasure trove of technology that can be borrowed directly.

Then Li Yian opened the "skill information exchange" of the system, and soon found the information about radial tires under the "tire design skills" column.

"It actually costs 2000 experience points, but the technology is expensive!"

While sighing, he looked at the message "Whether to extract "Radial Tire Design" flashed on the light screen. When he clicked "Extract", along with the white light that was not visible to outsiders, a thick, unpublished The book appeared out of thin air in Li Yian's hands without a printing date.

Afterwards, Li Yian looked at the information and "designed" the radial tires with a pen.

Once people focus, they forget time. Li Yian, who was obsessed with design, got up again in the evening. Although he didn't have lunch, he went straight to the tire company in the industrial park after leaving the library.

As a key enterprise in the first phase of construction, Borneo Tire Company has completed the overall construction and installed all equipment in the factory. Although it has not yet been put into actual production, the first batch of tires was produced at the beginning of the month.

Although it was already seven o'clock in the evening when we arrived at the factory, there were still many people busy in the factory area - the factory building was completed, but the greening of the factory area, office buildings and corresponding ancillary buildings were still under construction.

"The carcass cords of this kind of tire are not arranged crosswise with each other, but are nearly parallel to the tire section, like the earth's meridian arrangement, so I call it a "radial tire." Its cord angle is small, usually 0°. There is no maintaining intersection between the carcass cords..."

In the design room of Office Building No. 1, when Li Yian explained the design of radial tires, Weeks and several other engineers listened extremely seriously. At first, they did not believe the tires designed by Chief Li, but now As he explained, these people were all keenly aware that this tire would bring about earth-shaking changes to the tire industry.

"... When the tire is driving, the stress around the crown increases, which will cause circumferential stretching and the carcass to form radial cracks. Therefore, the buffer layer of the radial tire uses a cord layer arranged close to the circumferential direction, which is in contact with the carcass The cord angles intersect at 90°, forming a rigid annular belt that is almost inextensible, fixing the entire tire and limiting the circumferential deformation of the tire. This buffer layer bears 60% to 70% of the internal stress of the entire tire, becoming the main component of the radial tire. It is a force-bearing component, so it is called the belt layer of a radial tire.”

Weeks, the tire expert sent by Goodyear to guide production, realized from Li Yi's explanation that traditional fibers would definitely not be able to meet its requirements.

"Sir, this belt must have very high material requirements!"

"Yes, the design of the radial tire belt is very important. It must have good rigidity. It can use multiple layers of materials with large angles, high strength and not easy to stretch, such as steel wires..."

Li Yi'an, who originally wanted to say "nylon", stopped when he said it, because Dupont would definitely worry about the application of nylon after the war. For him who wanted to take away the golden doll, he naturally stopped talking.

It took almost an hour for Li Yian to explain his design clearly, and then looked at Weeks and the others and asked.

"How about it? When can we produce it?"

Looking through the design drawings carefully, Weeks thought for a while and said.

"The factory has a test workshop, and the raw materials are readily available, but there is no suitable steel wire. It requires very thin and high-strength steel wires as cords, so..."

Before he could finish speaking, Li Yian said.

"You can also use Manila hemp. Although the performance is slightly inferior, it can still meet the basic needs."

Manila hemp is sisal. Because of the strong strength of sisal fiber, it has long been used in tire manufacturing. During the war, in order to obtain enough sisal to produce various materials including tires, the U.S. military sent out troops to African and other producing areas. The commissioner is in charge, and the curtains used in the factories in Borneo are made of sisal because they are close to the Philippines. Before the war, the Philippines was also an important producer of hemp, otherwise it would not be called Manila hemp.

Moreover, radial tires can be divided into three types according to different materials: all-steel radial tires, semi-steel radial tires and all-fiber radial tires. The carcass and belt layer of full-fiber radial tires are all made of nylon or other fiber cords. The belt cords should be low-elongation cords. This type of radial tire is generally used on low-speed cars or tractors. This type of tire is used Just right on a farm tricycle.

Since we are going to invent radial tires, we should get the patents for these three types of radial tires in our own hands.

Taking other people's paths and leaving others with no way to go is the correct way for a time traveler to operate.

"After we get the appropriate steel wire, we can manufacture steel wire tires and tires that are a mixture of steel wire and fiber wire. For now, we will use fiber wire."
