Thermoplastic Carbon Fiber Prepreg (Kyron™ULTRA)
※This is a product in the development stage.
Kyron™ULTRA is a new sheet-like intermediate material
developed by Mitsubishi Chemical, in which carbon fibers are
impregnated with engineering plastics. It is a high performing
carbon fiber composite material in the form of a UD
(Uni-Directional) prepreg with carbon fiber in one
direction.

Features
Kyron™ULTRA, which is benefited from Mitsubishi Chemical's expertise in carbon fiber technology, resin engineering, and composite material design, offers the following characteristics:
Performance
A prepreg that makes the most of the characteristics of carbon fiber and thermoplastic resin with our composite material technology.
High quality
Kyron™ULTRA features ultra-low voids and high dimensional accuracy, making it applicable for thermoplastic ATL (Auto Tape Layup) molding technology, general-purpose stamping technology, etc.
High formability
With ultra-low voids, takt time (process work time) can be shortened in general-purpose stamping. In addition, freezer storage of materials is not required.
This image demonstrates that the internal void is kept to a minimum.
Applications
Making the most of the anisotropic nature of carbon fiber,
UD prepreg can greatly expand the range of product design by
placing the necessary prepreg in the right place.
Harnessing the characteristics of both carbon fiber and
thermoplastic resin, it can be used in a wide range of
fields such as aerospace, industry, mobility, and
snowboards.
