In the early stage of the development of materials science, there was no shortage of surprises caused by various accidents, and perhaps adding guano to the boiling slime glue would also produce miracles.

Charles was holding a palm-sized white and yellow slime hard rubber board in his hand, knocking here and there from time to time, and he couldn't imagine that he would come up with such a thing after adding the wrong additives.

As soon as his thumb and forefinger strained, the rubber plate did not deform much, and one corner was broken. It seems that the hardness of this rubber sheet is not low, but it is somewhat brittle.

Lang Sha said on the side: "Can this hard rubber be used?"

Charles thought and said, "It's still brittle, I think it will be better if you put a skeleton in it." ”

Lang Shake said, "What are you going to use to make a skeleton?"

This is a difficult time for Charles, who is familiar with materials such as fiberglass cloth that are not available in this world.

"I'll look for it. Charles said, "You first find a way to prepare enough hard rubber board raw materials, and I will start experimenting when I find the skeleton materials." ”

Lang Sha could only agree: "Okay then, I'll prepare the additives today, and tomorrow Enrico and they will come back and start mass production." ”

After confirming that the amount of additives was sufficient, Charles left Langsha's office.

Now it is less than half an hour after the meeting just now, and everyone's task in the morning is to make all kinds of preparations, find people, prepare materials, and start formal work in the afternoon.

Charles walked to the faculty building to seek help from the professors, thinking about the reinforcement materials used in the hard plywood.

Although the relationship between the slime hard rubber as the base and the skeleton is like concrete and steel bar, the processing is almost the same as that of FRP.

The process of making FRP is not difficult for him, he has participated in the production and installation of FRP ventilation pipes in a project when he just worked in his last life, and he is clear about the production and processing process of FRP components, and it will be used for this time.

Now this reinforcing material needs to have enough tensile strength firstly, secondly it needs to have enough bond strength with the substrate, and thirdly, it is best to have ready-made ones, and the price should not be too high.

Limited by the current level of productivity, Charles found the material a little difficult to find.

At this moment, the faint smell of perfume wafting around him caught his attention.

A pair of twin girls in beautiful dresses walked past him with parasols.

A pair of eyes instantly focused on the stockings under the girl's skirt, and it should be possible to use fabric as a reinforcement material.

It's just that the silk stockings wrapped around the girl's jade feet are too smooth, and I'm afraid it can't be effectively bonded to slime glue. Moreover, silk and spider silk are afraid of high temperatures, and slime glue that is still hot may cause damage to it.

After vetoing silk and spider silk, Ruyan searches around the campus for inspiration.

At this time, a roll of cloth in the hand of a girl who approached attracted Charles's attention. It was a sparse warp and weft linen, and the other side of the cloth could be seen when you were close.

Charles thought that if the linen used to make the mosquito net was strong enough, it would seem good to use it as a reinforcement material.

Many professors in the college would be in the office on the morning of their day off to deal with official business, Charles came to the floor where the professors of materials science were, and found Henry with the note that the president had just written. Professor Bhatsia.

Professor Battisa is the college's chief professor of materials science, a master of steel materials, and Charles was sitting behind his desk wiping his glasses when he knocked on the office door.

The door opened automatically, and the guests were a little surprised to see that it was opened by a robotic arm fixed to the wall behind the door, which automatically closed the door after Charles walked into the office.

Charles went to the extraordinarily long desk and handed over the headmaster's note, explaining his intentions.

"Sit down. Professor Bhatsia asked him to sit down in the chair opposite, "Tea or juice, wine is fine." ”

Charles replied: "Tea is fine, I don't drink alcohol at work." ”

The professor was very satisfied with his answer, saying, "The rule of 'don't drink when you go to work, and don't go to work if you drink' is something that everyone should follow." ”

Charles was not surprised by the professor's words, because there was a palm-sized golden hammer on the desk, which exuded the red divine power of the forging god, proving that the other party was the priest of the forging temple.

Professor Battisia pressed a few buttons on a row of buttons next to his desk, and the large box at one end of the desk partially opened, and several slender metal arms stretched out from it, some of them placed the teacup in front of the two of them, and the other arm poured a small spoonful of tea into the teacup, and the last arm came over with a steaming kettle and poured most of the boiling water into the teacup.

Charles was stunned by his hand, but his face remained unchanged as he watched the mechanical arms retract before finally picking up the lid and closing it back.

Professor Bhatsia smiled and said, "My tea here is not very good, please forgive me." ”

Charles also smiled and nodded, this tea pouring machine is indeed a powerful tool to improve the grade of the office.

He placed a slime rubber plate on the table and talked about the idea of using reinforcement materials to strengthen the toughness of the material.

Professor Batisia held the teacup and nodded slightly, but said, "Do you want to use steel wire to inlay in, like reinforced concrete?"

As a big bull in the materials science industry, "Charles Rebar" will naturally know about this kind of thing.

Charles replied, "I'm not going to use metal this time, because the bond between slime glue and metal is insufficient. ”

As a result, Professor Bhatsia looked at this guy with a "hehe" look and said, "That is to say, if the two can be tightly condensed together, then it is qualified?"

Charles nodded and replied, "Yes, and in addition to the production relationship." ”

Professor Bhatsia got up and left his desk and pulled out a thick book from the nearby information cabinet.

Charles was amazed at the weight of the book when he took it, and even more surprised at its contents when he opened it.

On each page of the parchment in the book is a thin piece of metal mesh woven into a wire about the thickness of a human hair, and the characteristics of these metal nets are written in the margins.

Professor Bhatsia said: "In recent years, the research on mesh armor has been very popular, and our college has achieved a lot of results, and I think it can be used this time." ”

Charles looked at the specimen and was shocked to realize that he had neglected the magic of forging the temple, which seemed to be able to bond the two materials together.
