Preparation method of FeSi2 modified C/SiC braking material
The invention relates to a preparation method of a FeSi2 modified C/SiC braking material. A method combining CVI with RMI is adopted to prepare the FeSi2 modified three-dimensional needled C/SiC braking material. The preparation method includes: taking FeSi75 alloy powder as a RMI infiltration raw material; obtaining the FeSi2 modified C/SiC braking material through a reactive melt infiltration (RMI) process. By the preparation method, raw material cost is lowered remarkably, and RMI process temperature is lowered; a FeSi2 phase is introduced into a C/SiC composite material, so that strength and heat conductivity of the braking material are improved, friction stability is improved, and wear rate is lowered.
