The optimisation of the fiber/matrix interface of ceramic and metallic fiber composites has been researched at the IMTCCC for years. Surface treatments with fibre coating can serve many purposes:
- Targeted control of fiber/matrix adhesion
- Reaction and diffusion barrier: protection of fibres against chemical attack
- Increased wettability of fibres with molten metals
- Optimization of the oxidation resistance of carbon fibers
The IMTCCC's approach to fibre coating as an alternative method to chemical vapour deposition (CVD) was systematically investigated in 1998-2004 as part of the DFG's research programme. The coating line at the IFKB is currently designed for the coating of commercial 12k carbon rovings.
