Continuous Heat Treatment: Carbon Fibres
Carbon fibers or carbon fibres (alternatively CF, graphite fiber or graphite fibre) are a modern material for high-tech applications. The fibers are about 5–10 micrometres in diameter and composed mostly of carbon atoms. Carbolite Gero offers three main types of furnaces for carbon fibre R&D and production.
The precursors for carbon fibres can be introduced into a tube furnace with metal work tube for debinding through inert gas counter flow flanges.
When introduced into a tube furnace with a ceramic work tube pre-sintering of the carbon fibres up to 1300°C can be achieved.
For temperatures above 1800°C, a water cooled vessel with graphite heaters and insulation is required for final sintering of the carbon fibres up to 2200°C.
Up to 4 fibres can be heat treated in one furnace at the same time.
