We offer various forms of materials including UD prepreg in which carbon fibers are drawn uni-directionally and impregnated with resin and cross prepreg which is carbon-fiber-woven cloth impregnated with resin.
In particular, products using DIALEAD, that is ultra-high modulus pitch-based carbon fiber are widely used as materials essential for manufacturing of parts and components for various industrial machines represented by carbon rollers and robot hands. Other applications include sports, construction / civil engineering, and aerospace industries.
The HX1 Series is a prepreg impregnated with special epoxy resin developed on the assumption of use in a high temperature range. Using this prepreg, it is possible to expand the range of applications of CFRP products.

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.

Mitsubishi Chemical continues to develop an ever-expanding value chain from raw materials to final product through the use of PAN-based carbon fiber and pitch-based carbon fiber.

Carbon fibers are one quarter the weight of steel but have about 10 times the strength; thereby creating a light and tough material that is stronger than conventional metal materials. Carbon fibers have a variety of features that include being electrically conductive, strongly wear-resistant, and transparent to X-rays. They are mainly used in composite materials in combination with plastics.
Mitsubishi Chemical's carbon fibers have obtained the Japan Industrial Standard of quality management system for the aerospace and defense industry (JIS Q 9100), and we are continuing to raise our quality control levels further still.

PYROFIL™ carbon fiber and its composites, are advanced high-performance materials born from technology centered on synthetic high polymer chemistry, in which Mitsubishi Chemical excels. We have an integrated framework for production that includes polymerization of acrylonitrile (PAN), spinning of PAN fiber (precursor),carbonization of a precursor (carbon fiber), weaving, prepregging, and chopping of carbon fiber.
