Preparation method of silicon nitride@silicon carbide@boron nitride composite fiber felt
The invention discloses a preparation method of a silicon nitride@silicon carbide@boron nitride composite fiber felt, and relates to a preparation method of a composite fiber felt. The invention aims to solve the problem that the use temperature of an existing ceramic fiber material is lower than 1200 DEG C. The preparation method comprises the following steps: 1, preparing a Si3N4 fiber felt; 2, coating a carbon layer; 3, preparing a Si3N4@SiC fiber felt; and 4, loading a BN layer. The method is used for preparing the silicon nitride@silicon carbide@boron nitride composite fiber felt.
