"Development of Technology for Recovery and Reutilization of Carbon Fibers from Waste CFRP Using Alkaline Hydroxide" is a document about research that promotes the decomposition of resin without breaking down carbon fibers by conducting thermal decomposition of CFRP (carbon fiber reinforced plastic), which is a composite material made of carbon fibers and resin, in the presence of alkaline hydroxide. It provides detailed explanations on the research background, objectives, the effects of thermal treatment on carbon fibers in the presence of sodium hydroxide, as well as experimental results such as the strength evaluation of recovered carbon fibers. Comparisons with combustion methods and applications to various products are also included with accompanying photographs.

Carbon nanotubes have a structure that resembles a cylindrical shape formed by rolling graphite sheets with carbon atoms arranged in a hexagonal pattern, but their properties change significantly depending on the way they are rolled (chirality). CNTs exhibit unique electrical characteristics due to their high aspect ratio, as they are very long relative to their diameter, and can become semiconducting or metallic depending on the size of the diameter and the way the graphite sheets are rolled. They have various features such as high electrical conductivity and thermal conductivity, and high mechanical properties. Ultra-fine/lightweight: Nano-sized/half the weight of aluminum High mechanical strength: About 100 times that of steel High conductivity: About a thousand times that of copper, higher than silver High thermal conductivity: About 10 times that of copper, higher than diamond High melting point: Over 3000 degrees (in an oxygen-free state) Flexibility: Very flexible and strong against bending and stretching Chemical stability: Stable against chemical reactions Temperature stability: Stable against temperature changes High corrosion resistance: Excellent corrosion resistance High lubricity: Excellent lubricity

It is composed of zonotlite crystals with excellent heat resistance, making it suitable for applications where molten aluminum alloys come into direct contact. By reinforcing with special fibers, it can withstand thermal shock caused by high-temperature molten aluminum, achieving continuous use and long lifespan. Due to its low thermal conductivity, it has a high temperature retention effect for molten aluminum, contributing to energy savings in manufacturing equipment. It has excellent machinability and can be used for cast components with complex shapes. (It is also possible to machine various shapes.)

The reason why the market does not respond to conventional recycled products is that... we become too fixated on the format and start considering risks from the beginning. a. To establish CFRP recycling, it is necessary to ensure material traceability and a stable supply of waste materials. b. We will conduct demonstrations to build a system for consistent processing from carbon fiber recovery to the final product. c. I believe it is necessary to continue addressing business challenges such as building product recipes, quality control, stable supply, and evaluating business viability in collaboration with specific customers. d. I believe that developing while balancing "environmental conservation," "social benefits," and "economic advantages" is what constitutes a sustainable society. Of course, I think the above content is very important. However, before that... I believe it is more of a priority to take action and build what the market needs.

The classification technology has existed since ancient times, but our crushing and classification technology does not have a dynamic structure in the classification part, allowing us to consistently maintain a uniform particle size distribution regardless of the passage of time. It is a unique method unlike any other.

The silica sand sorted according to JIS standards is particularly lacking in larger particles because the starting material is finely ground. Therefore, our company has developed a new product to replace the JIS-grade silica sand. Additionally, while markets with high prices, such as biomass and fluid sand, have stable supply, there is a shortage in lower-priced materials like construction materials. Since our company owns a mine, we have been able to secure a supply quantity of several yen per ton per month by intervening from the production stage.

Introduction to Micro Silica Powder CFP-M3: While conventional ceramics were made by sintering particles of about several tens of micrometers, fine ceramics have achieved the following advancements: 1. The particles of the sintered body have been reduced to several micrometers. 2. Dimensional accuracy has improved. 3. It has become possible to manufacture thin films, fibrous materials, and fine particles. 4. The control of pore diameter in porous bodies has become precise. These characteristics indicate that the technological scope of fine ceramics has broadened. Even with the same material, different forms lead to different functions, and consequently, different applications, which expand the field. One of the significant differences between fine ceramics and traditional ceramics lies in the extent of artificial processing applied to naturally occurring raw materials. Therefore, it is not an exaggeration to say that research on fine ceramics begins with the synthesis of starting raw powder and the study of fine powders. The general characteristics required for raw materials to obtain high-performance fine ceramic sintered bodies are as follows: - They must be fine particles. - There should be no particle agglomeration. - The particle distribution should be narrow (with uniform particle size). - The particle shape should have low anisotropy (spherical). - They must be chemically high purity.
