Bespoke CFC Composites.

High function CC Composites materials

Bespoke CFC Composites

Whether it be Robotics used in Glassware, Magnet production, medical furnaces or sealing valves used in Oil and Gas industries. Our expertise allows us to produce and supply materials that suited to our customers specific industry requirements.

Sometimes a stock CFC Composites will not be adequate for very specific application which is why users need to consider a bespoke CFC composite. At Neftec we are able to design and manufacture Bespoke CFC Composites which are unique to our customers specific requirements. Bespoke composites can range from non-standard sheets and plates to changes in the technical aspects of the composite itself. This can include higher density, electrical resistivity or even ash content. 

Due to our unique ability to be able to quickly alter the properties of our CFC composites with ease. We are able to produce a bespoke CFC composite efficiently and competitively.  Our engineers will work with you and Neftec will help develop a CFC Composites materials and product that is specific to you. Allowing your business to overcome obstacles that you once had with your existing methods and ultimately allowing you to grow. Key points:

  • Exceptionally high inter-laminar strength
  • Can quickly increase the density of our composites
  • Retains strength throughout continuous heat cycles
  • Reduced costs and overheads
  • Fast lead-times.
