Pitch-based carbon fibers have the characteristics of being lightweight and high rigidity. Machine parts made utilizing these characteristics have the advantages of low deflection and low moment of inertia, as well as a high natural frequency, significantly contributing to the performance improvement of components such as rolls and propeller shafts. In recent years, their application to high-speed rotating bodies such as motor covers and flywheels is anticipated. *For more details, please refer to related products and catalogs, or feel free to contact us.*

We would like to introduce examples of the utilization of carbon fiber/carbon fiber reinforced plastics (CFRP). Mitsubishi Chemical provides a variety of carbon fibers by utilizing both PAN-based and pitch-based raw materials. These carbon fibers, combined with resins, are widely used in aerospace, sports and leisure, and industrial applications. The use of CFRP improves lightweighting, reduces deflection, and enhances vibration damping, making it possible to shorten tact time. *For more details, please refer to related products and catalogs, or feel free to contact us.

CFRTP refers to fiber-reinforced plastic that uses CF (carbon fiber) as a reinforcing agent and employs thermoplastic resin instead of thermosetting resin as the matrix resin. Compared to conventional thermosetting resin CFRP, it significantly shortens the molding cycle and enables bonding through thermal fusion, thus achieving improved productivity and lower costs. Additionally, it excels in impact resistance and fatigue properties, and can also provide flame retardancy and heat resistance depending on the type of resin used. *For more details, please refer to related products and catalogs, or feel free to contact us.*

We will introduce examples of the use of carbon fiber/carbon fiber reinforced plastics (CFRP) for semiconductors. Mitsubishi Chemical provides a diverse range of carbon fibers by utilizing both PAN-based and pitch-based raw materials. The characteristic properties of carbon fiber are its light weight, high strength, and high elasticity. As carbon fiber composite materials combined with resin, they are widely used in aerospace, sports and leisure, and industrial applications. *For more details, please refer to related products and catalogs, or feel free to contact us.

C/C (Carbon Fiber Reinforced Carbon) composites are reinforced with carbon fibers using carbon as the matrix. They possess high strength, high elasticity, high toughness, and ultra-high heat resistance, making them usable at temperatures above 1000°C. They are suitable for applications such as brake materials and heat-resistant components in industrial machinery. *For more details, please refer to related products and catalogs, or feel free to contact us.*

"Diaryl Composite" expands the design flexibility in various industrial fields due to the lightweight and high rigidity characteristics of pitch-based carbon fibers, which provide excellent vibration damping and improved critical rotational speed. It has higher thermal dimensional stability than metals and allows for zero thermal expansion coefficient design. It possesses the characteristics of plastics and is not affected by magnetic forces. One of its features is that it has a higher thermal conductivity compared to general plastics. *For more details, please refer to related products and catalogs, or feel free to contact us.*

Mitsubishi Chemical Corporation offers "Ceramic Matrix Composite Materials (CMC)" that combine lightweight properties, rigidity, and moldability. Our CMC materials, which combine carbon fibers and metal materials, possess characteristics such as high rigidity, high heat resistance, high thermal conductivity, lightweight, wear resistance, and low dust generation, and are used as brake materials in mobility and as components in industrial machinery. Additionally, we are also exploring high moldability and associated cost reduction while maintaining the characteristics of these CMC materials. *For more details, please refer to the related products and catalog, or feel free to contact us.*

Mitsubishi Chemical Corporation has developed a carbon fiber reinforced plastic (CFRP) that balances lightweight properties, rigidity, and high heat resistance. By using phenolic resin as the base material, this product achieves high heat resistance that does not degrade even at 300°C. In addition to its characteristic high thermal conductivity, high rigidity, and lightweight properties, the addition of high heat resistance enables the provision of solutions to customer challenges. *For more details, please refer to the related products and catalog, or feel free to contact us.

The demand for lightweight materials is increasing in mobility applications such as aircraft and automobiles, as well as in industrial machinery applications that require responses to the sophistication and complexity of manufacturing processes along with efficiency improvements. The use of CFRP, which combines lightness and strength, is expected to advance further in the future. Mitsubishi Chemical has developed CFRP with high heat resistance that maintains its properties even at 300°C by using phenolic resin as the base resin. This CFRP, which uses phenolic resin, not only possesses the high thermal conductivity, high rigidity, and lightweight characteristics of CFRP based on epoxy resin but also offers high heat resistance, enabling solutions to customer challenges that have been difficult to address until now. *For more details, please refer to related products and catalogs or feel free to contact us.

"Carbon fiber" is a material said to have a strength ten times that of steel and a weight one-fourth of it. We utilize the characteristics of two types of carbon fibers with different raw materials: "PAN-based carbon fiber," which has high strength, and "pitch-based carbon fiber," which features high elasticity, for various applications. Most cases involve using carbon fiber not alone, but as a composite material combined with resin. There are numerous examples of its application in various fields, including FPD transport devices, semiconductor manufacturing equipment, train pantographs, industrial machinery, and picking robots. *For more details, please refer to related products and catalogs, or feel free to contact us.*

We have created a document summarizing the key points of CFRP component development for designers, developers, and engineers who are considering the use of CFRP materials. In the previous edition, we discussed design aspects, but this time we have compiled points related to manufacturing, which have received many inquiries, so we hope you find it helpful.

We have prepared a document that outlines the key points for CFRP component development for designers, developers, and engineers considering the use of CFRP materials. It clearly summarizes the points of CFRP design, including the differences from isotropic materials, and we would greatly appreciate it if you could take a moment to read it.

Mitsubishi Chemical manufactures lightweight material "carbon fiber." In addition to selling carbon fiber, we also perform molding and processing, allowing us to deliver in the form of final products. By using carbon fiber composite materials, which have characteristics of high strength, high elasticity, and low specific gravity, it is possible to reduce the weight of parts, so please take a look at the materials first.
