CFC Composite Friction Materials.

CC Composites for Heat-Treatment

CFC Composite Friction Materials

Neftec has a long standing history with Motorsport and many early developments of their Short-fibre came from the development of high performing friction materials since the late 1980s. Neftec’s expert knowledge was gained by working closely with leading manufacturers and Motorsport teams including Formula Atlanta series in Japan. This lead to the development CFC Composite friction materials for , differentials and clutches and brakes for both automotive and aerospace applications. 

Neftec doesn’t just focus on motorsport applications, we have also worked on researching and developing applications for general automotive use as rail as rail applications, which includes Pantograph sliding boards for electrical pickups. 

The advantages of Neftec’s CFC Composite friction materials are; weight savings, resistances to fade, long-life and strength. And in today’s modern world where energy savings and economy are key, these attributes are vital for today’s automotive and aerospace industries.  

Using Neftec Carbon/Carbon Composites can offer significant weight savings thus reducing energy consumption. Typically Carbon Composites used for Automotive and Aerospace brake rotors can be between up 50-65% lighter than their steel counterparts.

While Carbon/Carbon Composite clutches help reduce the rotating mass in a vehicles transmission, thus helping to reduce energy consumption. At Neftec we offer class leading friction materials that can be specifically tailor made to suit our customers’ needs.
