Bespoke C/C Composites

Not all Industries are the same and not every application is the same. And even though Neftec have produced one of the best multipurpose C/C Composites in the form of PC70. There may still be a requirement from customers to have a C/C composite that is suited to their specific needs. 

Industries such as Glassware, Magnet production, Heat-treatment for Medical appliances and Oil and Gas industry are just some whom can have specialist requirements. Our expertise allows us to produce and supply materials that suited to our customers specific industry requirements.

Neftec offers a range of bespoke services, this includes bespoke C/C Composite production. This is a composite that is manufactured to suit a specific environment. This can include different structural properties, C/C coatings to custom sizes and thicknesses. Neftec will work with you design to manufacture your bespoke C/C material which is unique to you and your application requirements. 

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, quickly and competitively. Neftec engineers will work with you  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.
