Aerospace.

 

Carbon Carbon composites (C/C) are a stable part of the aerospace industry, this includes for the construction and manufacturer of aerospace components to being used in aircraft brakes.

Typically production within the Aerospace industry requires strict controls and safety measures means and as such only the very best materials can be used. When it came to composites 3D Carbon/Carbon was always a primary choice and still is for some applications. But with the advancement of our 2.5D Short-fibre Carbon Carbon which offers a similar performance. Many applications and users can now switch to a more economical Carbon Carbon composite, especially if their primary use is for Heat-treatment applications.

No mater where the Carbon Carbon Composite is used in the aerospace sectors, it has to meet the highest of requirements and demands. Neftec offers a material that can meet these demands and go beyond the customers requirements.

Providing fixtures and fittings for Heat-treatment is a growing market, replacing existing heavy graphite and alloy fixtures is allowing our aerospace customers to increase output, reduce overheads and provide a higher performing product.

While another big drive for Neftec is increasing our activities in the commercial space exploration. Helping companies produce next generation satellites and deep space engine components.

Applications

  • Heat-Treatment fixtures and fittings for Turbine blades
  • Aviation Brake materials
  • Next Generation aerospace engines – C/C Composite Grids for Ion drives
  • Engine components – Sealing vanes, bearing guides
