Carbon ceramics, or to give the full name, Carbon Fibre Reinforced Ceramics, are carbon composite materials which combine the stiffness and strength of carbon fibre in a carbon matrix, with the high temperature resistant properties of ceramics such as silicon carbide, which replace part of the carbon matrix material.
Melt infiltration with silicon is often used for the formation of the ceramic phase. Molten silicon has a very low viscosity and will flow, water-like through the carbon composite, reacting with carbon to form silicon carbide. The design of equipment to facilitate this process and to deliver high quality composite materials is part of the expertise we offer.
There are other methods including the use of pre-ceramic polymers containing SiC within their chemical structure. Starfire Inc. of the USA is a leading developer of this technology.
