Quartz fiber reinforced SiO2-BN multiphase ceramic composite material as well as preparation method and application thereof
The invention discloses a quartz fiber reinforced SiO2-BN multiphase ceramic composite material as well as a preparation method and application thereof, and belongs to the field of ceramic composite materials. The ceramic composite material provided by the invention is prepared from the following raw materials in percentage by volume: 45-55% of a quartz fiber woven part, 40-48% of SiO2 and 5-7% of BN. The preparation method comprises the following steps: firstly carrying out heat treatment on a quartz fiber woven part, then carrying out dipping curing twice in a silica sol solution, and then carrying out dipping curing twice with borazine to obtain the SiO2f/SiO2-BN composite material. The composite material disclosed by the invention is excellent in mechanical property, simple in preparation process, relatively low in preparation cost and relatively small in loss of mechanical property and thermophysical property, meets the requirements of spaceflight and high-end weaponry on material performance, and has a very good application prospect in the fields of spaceflight radomes and high-end weaponry.
