Abstract
The invention discloses a method for preparing a fiber-reinforced ceramic matrix composite material with a low thermal expansion coefficient, comprising: firstly, carrying out structural weaving of a fiber preform, and the material of the fiber preform is carbon fiber or silicon carbide fiber, or a combination of the two ; secondly, the interfacial phase is prepared on the surface of the fiber preform; thirdly, the chemical vapor deposition process is used first, and then the fiber preform is densified by the impregnation and cracking process of the organic precursor. The invention can obtain the fiber-reinforced ceramic matrix composite material with low coefficient of thermal expansion.
Description
A kind of preparation method of fiber-reinforced ceramic matrix composite material with low thermal expansion coefficient Technical field [0001] The present invention relates to the technical field of ceramic matrix composite preparation, in particular to a fiber augmenter with a low coefficient of thermal expansion A method for preparing a strong ceramic matrix composite. Background technique Along with the rapid development of space technology, my country's space exploration depth and breadth are improving rapidly, and this is to space remote Sensitive detection systems put forward higher and higher requirements. The core of the space remote sensing detection system is the optical system, which is mainly composed of Composed of primary reflector, secondary reflector and camera barrel. The camera lens barrel is one of the very important components, and its front end supports Supporting the secondary reflector, the rear end is directly connected with the primary mirr...
