Metal plated CFRP rolls
CFRP (Carbon Fiber Reinforced Plastics) means plastics reinforced with carbon fibers; typically used for fishing rods and golf club shafts.

Features
Super light weight
It has only one-fifth of steel, realizing low inertia moment.

Various surface treatment techniques
Metal plating, ceramic thermal spraying, rubber lining are accommodated.

Low thermal expansion coefficient
Thermal expansion coefficient is almost zero, enabling high dimensional accuracy.

Vibration damping effect
It has high vibration absorption features, enabling high damping effect.
The damping time of CFRP is only one-third of that of steel roll in the same size.
