One example is a continuous production process for chemical vapor infiltration of silicon doped boron nitride onto individual filaments of multiple parallel processed silicon carbide fiber tows. The Si doped BN is used as an interphase to control the fiber-matrix bonding and transfer load between the fiber and the matrix in such a way that prevents brittle fracturing of the CMCs.

New Swedish Company To Develop Hot-wall CVD …

Much of the pioneering research around silicon carbide was done at Linköping University in Sweden, where the highly successful hot-wall CVD reactor type was developed. The hot-wall CVD reactor has been the workhorse in R&D labs all over the world, and a large nuer of scientific papers have been published around material grown in them.
