Problems solved by technology

Continuously reinforced ceramic matrix composite materials are relatively mature in the market at present, and their reinforcements are mainly short fibers, whiskers, particles, etc., and the materials are formed by simple methods such as slurry casting method and hot pressing sintering method. Low cost, but defects such as uncontrollable material structure and solid phase bonding hinder the further development of materials
Discontinuously reinforced ceramic matrix composites can control the structure of the material, and can be used in many working environments such as strong acid and alkali, high temperature, high impact and self-cleaning coatings, but due to its high cost and long production cycle, it is not currently available. Realize large-scale popularization and application [Bolin H E, Jia S. Materials Review, 2009.]
[0004] The current ceramic matrix composites have not achieved low-cost control of the material structure. The production mode is mainly based on traditional ceramic production modes such as dry mixing, wet mixing, and high-temperature sintering. The current research focus is mainly on the resin content, In terms of heating system, type of ceramic powder, length of fiber, type of fiber and other factors, future research will try to control the solid-state reaction process through accurate control of grain size, distribution and structure, and achieve low temperature, simple, Low-cost structuring control and high-performance ceramic matrix composite production

Abstract

The invention discloses a preparation method of a multilayer reticular zirconium oxide fiber reinforced resin-based material. According to the method, industrial ceramic waste is recycled and utilized, test methods which are easy to operate such as solid-phase reaction, infiltration and coating are adopted, and substances such as PTFE, resin, ethylene glycol, sodium carbonate and absolute ethyl alcohol related to the method are simple and easy to obtain. According to the structural characteristics of ceramic powder and zirconium oxide fiber cloth, a two-way interface modification mode is adopted, so that the bonding between interfaces is improved; the zirconium oxide fiber cloth with impact resistance, stress stretching resistance, light weight and high temperature resistance is combined with the ceramic powder by virtue of the excellent wrapping compatibility of the resin and the zirconium oxide fiber cloth, so that a zirconium oxide fiber cloth-resin-ceramic powder multi-element system with a reticular structure is constructed. The method has the advantages of greenness, environmental friendliness, low cost, simplicity and feasibility. The prepared reticular zirconium oxide fiberreinforced resin-based material is stable in structure, excellent in friction and wear resistance, high in high-temperature resistance, large in friction coefficient, light in weight and high in strength.
