Abstract

The invention provides a production method of a silicon carbide and titanium diboride compound ceramic material and application of the silicon carbide and titanium diboride compound ceramic material,and relates to the technical field of compound materials. The method comprises the following steps that methyl methacrylate, a cross-linking agent TAIC and polyvinylpyrrolidone are added into distilled water, and stirring and heating are conducted; titanium diboride and modified carbon fiber powder are added, ball-milling is conducted for 5-10 hours, then silicon carbide, cobalt powder, an emulsifying agent and polyethylene glycol are added, and after ball-milling is conducted continuously for 10-20 hours, mixed slurry is obtained; ammonium persulfate is added into the mixed slurry dropwise asan initiating agent, after dropping is completed, vacuumizing is conducted, a mixture is heated to 30-35 DEG C for reaction and transferred and injected into a mould, after heat preservation reactionis carried out at 45 DEG C for 10-20 hours, heat preservation reaction is carried out at 75 DEG C for 2 hours, finally, heat preservation reaction is carried out at 95-DEG C for 30 minutes, the mouldis taken out, and a green body is obtained; the dried green body is placed in a muffle furnace for heating and rubber discharging; the green body subjected to compression is placed in a sintering furnace for sintering. The silicon carbide and titanium diboride compound ceramic material is mediate in Young modulus and high in hardness, has certain impact toughness and a good effect of defending continuous multiple hits and can effectively protect the target.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a method for manufacturing a silicon carbide and titanium diboride composite ceramic material and its application. Background technique [0002] Bulletproof materials have always been the top priority of the research of military enterprises in various countries. Since the 1970s, the United States has begun to develop a new generation of ceramics, ceramics / composite bulletproof materials, among which alumina / high-performance polyethylene fiber, boron carbide / Aramid composite material is the representative. [0003] Since 2000, China has gradually started to develop and produce ceramic bulletproof materials. At present, domestic bulletproof materials mainly include alumina, boron carbide, and silicon carbide, each of which has its own advantages and disadvantages. The density of alumina is high (3800kg / m 3 ), low hardness (1800kg / mm 2 ), but cost-effective; boron car...
