Carbon Carbon composites (C/C) are a stable part of the aerospace industry, this includes components for satellites, aircraft braking system to general heat-treatment for aircraft components.

Typically production within the Aerospace industry requires strict controls and safety measures and as such only the very best materials can be used. When it came to CFC 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 it now offers a similar performance to 3D Carbon/carbon however 2.5D is far more economically viable. And today we are seeing a shift in this industry with more uses switching to Neftec’s short-fibre composites. Especially if their primary use is for Heat-treatment applications.

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

We provide fixtures and fittings for Heat-treatment, including bespoke design services. And help our customers transition from existing heavy graphite and alloy fixtures to lighter, more robust CFC fixtures and fitting.  This switch allows our aerospace customers to increase output, reduce overheads and provide a higher performing product.

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.
