"Carbon fiber" is a material said to have a strength ten times that of steel and a weight one-fourth of it. We utilize two types of carbon fiber with different raw materials: "PAN-based carbon fiber," which has high strength, and "pitch-based carbon fiber," which features high elasticity, for various applications. It is mostly used not as carbon fiber alone but as a composite material combined with resin. There are various case studies of its introduction in applications such as FPD transport devices, semiconductor manufacturing equipment, train pantographs, industrial machinery, and picking robots. *For more details, please refer to the PDF materials 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 variety of carbon fibers by utilizing both PAN-based and pitch-based raw materials. The characteristic properties of carbon fiber are that it is lightweight, has 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. 【Product Example】 ■ Application: Semiconductor manufacturing equipment ■ Adopted part: Pick ■ Required characteristics: Lightweight/high rigidity/vibration damping/heat resistance ■ Size: Total length 400mm/total width 150mm/total height 2mm ■ Weight: 80g *For more details, please refer to the PDF document or feel free to contact us.

CFRP is a composite material made of carbon fibers and resin. 【Benefits of CFRP】 - High specific modulus (modulus of elasticity ÷ weight), enabling lightweight parts, thin-walled designs, and reduced deflection. - Excellent vibration damping properties, allowing for high-speed operation. - Low thermal expansion coefficient, enhancing dimensional stability. - High thermal conductivity, enabling lightweight heat dissipation components. 【Common Needs】 - Desire to make products thinner and reduce deflection due to limited vertical space in equipment. - Need for materials with high Young's modulus because the weight of the workpiece has increased. - Requirement for lightweight components for high-speed operation. - Need to suppress vibrations to shorten tact time. 【Main Applications of CFRP】 Parts for FPD manufacturing equipment, semiconductor manufacturing equipment, automotive manufacturing equipment, medical device parts, machine tool parts, parallel link robot parts, conveyor equipment parts, inspection equipment parts, and other industrial robot parts, etc. 【What Mitsubishi Chemical Can Do】 In addition to manufacturing and selling carbon fibers and prepregs, we can also mold, process, assemble, coat, and inspect these materials, making delivery possible. *For more details, please refer to the PDF materials or feel free to contact us.

"Pitch-based carbon fibers" not only have lightweight and high rigidity but also possess the characteristics of low thermal expansion rate and high thermal conductivity. By utilizing the features of anisotropic materials, it is possible to impart physical properties (such as elastic modulus and thermal conductivity) in a targeted direction, as well as to design for zero thermal expansion in both the X and Y directions. As a manufacturer of pitch-based carbon fibers, we can propose appropriate CFRP designs that leverage the characteristics of the material. [Features] - Weight reduction of 40-60% possible (compared to aluminum and ceramics) - Quick vibration damping allows for reduced takt time - Thermal expansion rate can be made nearly zero - Can be used for parts where dimensional changes due to heat need to be minimized - High thermal conductivity prevents ignition due to heat dissipation - Can be used for heat dissipation applications *For more details, please refer to the PDF document or feel free to contact us.

CFRP, or carbon fiber reinforced plastic, is a composite material made of carbon fibers and resin. Due to its lightweight, high strength, and high elasticity characteristics, CFRP enables the reduction of weight in parts such as aluminum and stainless steel. By utilizing a "honeycomb structure" inside the CFRP, further weight reduction is possible. 【Benefits of CFRP】 - High specific modulus (modulus of elasticity ÷ weight) allows for lightweight parts, thin-walled designs, and reduced deflection. - Excellent vibration damping properties enable high-speed operation. - Low thermal expansion coefficient enhances dimensional stability. - High thermal conductivity allows for lightweight heat dissipation components. 【Common Needs】 - Desire to design in original shapes rather than off-the-shelf products. - Want to reduce weight while maintaining rigidity. - Aim to increase size without adding weight. 【Main Applications of CFRP】 Propellers for drones and eVTOLs, etc. 【What Mitsubishi Chemical Can Do】 In addition to manufacturing and selling carbon fibers and prepregs, we can also mold, process, assemble, coat, and inspect these materials, making delivery possible. *For more details, please refer to the PDF document or feel free to contact us.

"Pitch-based CFRP" features lightweight and high rigidity, enabling the reduction of weight in wafer transport hands and minimizing load deflection. Additionally, wafer transport hands made from pitch-based CFRP exhibit rapid vibration damping, contributing to shorter equipment cycle times. **Benefits of Using CFRP in Wafer Transport Hands** - High specific modulus (modulus of elasticity ÷ weight) allows for lightweight, thin designs and reduced deflection. - Excellent vibration damping properties enable high-speed operation and reduced cycle times. - Enhanced conductivity allows for static electricity prevention. **Common Needs** - Due to limited space within the equipment, there is a desire to reduce the thickness of the hands and minimize deflection. - As the weight of the workpieces increases, there is a need to adopt materials with high Young's modulus. - Lightweight hands are necessary for high-speed operation. - There is a need to quickly suppress vibrations in the hands to shorten cycle times. **What Mitsubishi Chemical Can Offer** We can manufacture and sell carbon fibers and prepregs, as well as design products using these materials. Furthermore, we can provide comprehensive support from molding, processing, assembly, coating, to inspection. *For more details, please refer to the PDF materials or feel free to contact us.*
