Pitch-based Carbon Fiber(CF)DIALEAD

DIALEAD is a pitch-based carbon fiber supported by many proprietary technologies as a result of coal chemistry by Mitsubishi Chemical over many years. The product is widely applied to fields such as aerospace, industry, and sports.

Key features and their characteristics

High Purity

DIALEAD has a high carbon content ratio, maintaining chemical stability of composite materials.
It has a structure in which graphite plates are highly oriented in the vertical direction of fiber.
This results in such features as lightweight, high stiffness, high thermal conductivity, and ultra low thermal expansion coefficient.

High Modulus

A full range is available to meet required strength and modulus.

  • Properties

Milled fiber

When mechanical strength is very different from that of carbon fiber or when carbon fiber is added to a matrix with low viscosity at the time of kneading, composite materials with excellent dispersibility can be obtained by making fiber short beforehand.

Standard grade

K6371M, K223HM

For the modulus of elasticity in tension and tensile strength of each grade, please refer to the relevant Physical Properties.

  • Properties

Fabric

We offer various fabrics, UD cloths, and prepregs.

Standard grade

F637400, FT37Y960, FT3C224

  • Properties

Applications

Aerospace

The coefficient of thermal expansion can be controlled by optimizing carbon fiber mixing, and can be made to zero, depending on design.
In addition to low thermal expansion, lightweight, and high stiffness, heat sink and other thermal controls can be realized, utilizing the product's property of thermal conductivity only in the orientation of the fiber.
