Chapter 360: Test blast

"The index of carbon fiber is t (tons). T is the unit of physical description of hardness. A cubic meter of material exerts a force of 40 tons upwards and produces a centimeter of deformation. We say that the elastic modulus of this material is 40t. The higher the t value, the higher the strength and elasticity of the material.
Ordinary carbon cloth is generally 20t-30t. hvf is 30t-40t, svf is 40t-60t. svf is lighter than hvf, with higher strength and better elasticity.
The material of ordinary domestic carbon fishing rods is generally 24t carbon fiber cloth.
However, you may have a misunderstanding that you need to pay attention to. High-tonnage carbon cloth is indeed added in the production of high-end fishing rods, but the entire fishing rod is not made of the same label carbon cloth!
As you should have seen just now, the carbon cloth used for winding rods is divided into multiple layers, which are divided into straight and reverse silk, and there are designs that increase the different performances of fishing rods.
According to different requirements, using different carbon cloth, after many times of design, improvement, debugging, and finally made one after another classic fishing rod! "
The system did not know when it was instilled into Yue Feng's mind. When Yue Feng whispered the live introduction, he didn't think much about it, and he spoke it out with his brain.
But when he finished looking up, he found that the students who had walked in the front were all gone, including instructor Yang Wenjian, who looked at Yue Feng with a monster look.
Being able to distinguish between different standards of carbon cloth is not a skill, and anyone with a little research in this area can be distinguished according to the label.
However, the standard that can clearly explain the carbon cloth tonnage is not what ordinary people can do. Even Yang Wenjian could not explain clearly what the specific T of the carbon cloth tonnage means.
Not to mention, Yue Feng also introduced the different rod making techniques such as smooth silk, reverse silk, and diagonal crossing very clearly and accurately, so that everyone can be surprised and justified.
Seeing so many people looking at themselves, Yue Feng scratched his head and said: "Sorry, it affects everyone to visit!"
Yang Wenjian didn't take it seriously, and said with a smile: "Yue Feng, you guys know enough! Don't be constrained, continue to tell everyone, on the level of business in this area, I'm really not as good as you!"
Yue Feng said modestly: "Yeah, I'm just talking nonsense, and I know nothing about it! I was curious about this before, so I checked the information specially, and I was deeply impressed, so I was ugly!"
The ugliness is a self-proclaimed statement. After some introduction, the impact on the students and the water friends in the live broadcast is still quite big.
Zhao Zheng whispered to Ma Tingting's ear: "What's the matter, my brother's knowledge is enough? Even the technical parameters can be clearly explained!"
Ma Tingting looked at Yue Feng with a slightly complicated look, Xu Jiucai pouted and said, "Cut, this girl knows now!"
...
After a few words, the effect in the live broadcast room was even more bursting.
"66666, Brother Feng talked so well, suddenly bright!"
"In terms of our business capabilities, who else is there in the whole network fishing anchor?"
"Understood, I learned something new!"
"In that case, is the 60t carbon cloth fishing rod on the Internet really chanting?"
Yue Feng shook his head: "As far as I know, this level of carbon cloth should not be used.
Although the high-carbon material is light in weight and strong in strength, it has low toughness and is very easy to break. The 46t carbon cloth used in conventional fishing rods is already a very high standard!
More than 90% of the advertisements that promote 60t, 80t and even higher tonnage materials are fooling! "
Hearing Yue Feng's continued introduction, Yang Wenjian patted his hand and applauded: "Yue Feng is right! Among the high-carbon fishing rods, materials with 30-40t labels are the most used, and 46t ones are generally only used on the previous sections. The head weight is used to increase strength.
However, the high-grade carbon cloth is rarely used, and it is generally only used on tens of meters of cannon poles! All those who promote ultra-high-tonnage carbon cloth are deceptive! "
After some introduction, everyone had a preliminary understanding of the material and production process of the fishing rod, and soon left the first workshop and came to the second workshop from the side door.
The structure of this workshop is a little more complicated. Most of the places are still very empty, but it is close to the northeast corner and separates a space. A lot of workers are assembling sections of fishing rods, and then fishing weight test, and then put the packing box into the storage,
"This is the R&D room of our fishing rod, and the last place to test the weight of the finished product before leaving the factory! Take everyone to see our professional testing equipment!"
Under the leadership of Yang Wenjian, everyone quickly came to the cubicle.
When I walked to the front, I discovered that the entire wall next to the compartment was drawn with a grid of horizontal and vertical lines, and the horizontal and vertical axes were marked with different data.
At the root of the wall, a professional test equipment is placed there, next to various weights.
"This is our professional testing machine for fishing rod testing! Let's take a look at the actual operation!"
Introduced briefly, Instructor Yang called out a staff member wearing staff clothing from the house.
After a brief exchange, the staff took out an unpainted black stick material rod, and then fixed it on the machine with three, five, and two, and added a weight to the position of the rod.
Press the machine switch, the fishing rod will be raised under the action of the machine. Soon due to the force of the weight, it bent into a radian.
Now everyone knows why the square on the wall is used.
The arc after the fishing rod is stressed can have a clear and intuitive understanding of the bending arc against the background grid. This can be much more scientific and reasonable than the normal test of the rod in the fishing gear store.
"This is the new pole material we are still testing! If you look at it now, the overall strength is performing well! Here's an excitement to give everyone a shot!" Yang Wenjian said.
Everyone looked forward to hearing about the explosion of the rod. ~EbookFREE.me~ Soon, the staff changed the weights on the rod in turn, and they picked it up again and again, and soon came to the 2000g mark.
"Everyone pay attention, according to the previous data, the top fishing limit of this test rod should be around 2000g, let's try to add a weight to 2100g! Everyone backed away, don't be affected by the shot!"
Soon, the staff added another 100g weight and fixed the machine and started the machine.
I saw that the lever kept rising under the action of the machine, the whole rod showed a perfect arc, and even the front end of the big began to deform.
Slowly, the largest two weights left the ground, followed by a small weight added later. At the moment when the weight just moved, only a crackling sound was heard, and the big curved bow a moment ago shattered, It exploded into more than ten festivals.
Ordinary fisherman hangs the blaster on the side of the mouth. This is the real blaster. Except for the front tip and the rear end of the handlebar, most of the other parts are 30 to 40 centimeters, especially the waist force. The position of the heavy three or four sections is extremely uniform.
