Science Museum (Kudanshita, Chiyoda-ku)It is a continuation of the story. Various experiments and hands-on programs are carried out in the museum, and all of them are available for immediate participation just by applying or going to the place (paid, but small amount ... some, but most of them. Things are free).
On the weekend I went with my children, when I passed in front of the experimental stadium on the 4th floor, my sister asked me, "I'm going to do an experiment now! I decided to take a look without.
The experiment was held by Toray and is called "Mystery of Senui". The content says, "You can see the mysterious phenomenon caused by the artificially created" sen "."
Hmmm, about fibers? Well, let's take a look. I started to look at it with ease, but Toray's older sister who was experimenting brought out a digital microscope and zoomed in on the fibers and weaves of "cotton" and "heat tech", and steam. It visually measures how the heat rises with cotton and heat tech in the situation where it is applied, and teaches children that "that's why heat tech is warm".
…When. At that time, the experiment was approaching the end. Isn't your sister saying, "Then, do you know carbon fiber next? It's a material that has recently come to be used in airplanes, etc."!
Until then, I had the feeling that I was watching the experiment with the children, but suddenly my eyes shined and I started to get excited about things that seemed to be related to cars, saying, "Because that is carbon fiber!" I did (laughs).
The older sister begins to give the children two boards, "The darker one is carbon fiber and the other is iron. Which is lighter?"
The children said, "Ah, the black one is lighter!" I actually compared carbon fiber of the same size and thickness with iron, and realized that "Oh, it's so different!" It was so light that it was no exaggeration to say that it was really different! That should be lighter.
Then, the older sister said, "But if it is so light, it may be weaker than iron, isn't it?" To the next experiment. "Deflection" was measured by placing 500 ml PET bottles on carbon fiber and iron of the same size and thickness cut into rectangles.
When this is "iron". It's quite a deflection. (The memory that represents the deflection is quite high).
Next, carbon fiber. Oh! Overwhelmingly little deflection!
"That's right. Carbon fiber is by far lighter than iron, but stronger than iron!" Well, it's understandable that supercars are already using a lot of carbon fiber!
While listening to this experiment and explanation, I was excited to show my children a picture of the smartphone and said, "Look! Is there a similar pattern in this Lamborghini Urus? The carbon fiber of the experiment I'm doing now is used! ", Said the heat valve (laughs). I'm not sure if this is a design or really carbon fiber (laughs).
Finally, while my sister was asking the children, "Do you have any questions?", I, my parent, asked me. I've been wondering for a while. "Why do all carbon fibers have the same pattern as carbon fiber?" I thought it would be nice to have more designs.
My sister said, "Because it is a carbon fiber weaving method (knitting method), this is what happens." However, it seems that carbon fiber is now being woven with various designs, so it seems that there is a possibility that various designs will come out.
Well, I'm glad I could unexpectedly experience the difference between carbon fiber and iron! It might have been an experimental classroom for me (laughs)! !!
