The best of both worlds
The new hybriCor roll design takes advantage of the combined properties of steel and carbon fibre for the design of high-speed rolls.
As a result, the runability and performance can be optimised to match a specific position.The core of a hybriCor roll is made of a stiff, lightweight CFRP tube produced in a fully integrated manufacturing process. The entire tube including journal connection is completed in a single manufacturing step before the final CFRP cure. This eliminates the need for bonded joints or bolted connections, ensuring a durable load transfer, high safety and enhanced manufacturing consistency.
The hybriCor shell is made of steel or stainless steel, which can be provided with delicate surface structures and patterns optimised for a specific installation position of the roll. In this way, the hybriCor concept brings together the unique properties of carbon fibre and steel in one.
