Preparation method of silicon carbide/silicon nitride composite fiber felt
The invention discloses a preparation method of a silicon carbide/silicon nitride composite fiber felt, and relates to a preparation method of a composite fiber felt. The invention aims to solve the problems that an existing SiC/Si3N4 composite material is long in heat preservation time, the quantity of Si3N4 in the product is difficult to meet, or the yield is low and the heat prevention and insulation performance of the product is poor. The preparation method comprises the following steps: 1, preparing an SiC fiber felt; and 2, preparing the SiC/Si3N4 composite fiber felt. The method is used for preparing the silicon carbide/silicon nitride composite fiber felt.
