[0174] 3. The preparation process of these multifunctional ceramics is different from the traditional preparation process and will include additional steps, which include the integration of the core material into the prepared initial ceramic slurry (also called ceramic green body), and the sintering process. Extra steps. The present invention provides the basic steps to be followed in the preparation of multifunctional ceramics, starting from the traditional method of combining refractory powders and then sintering, but does not exclude other potential routes and preparation methods that can be simply changed to achieve the same result.

[0175] The design of multifunctional materials can be performed using one of many commercially available numerical simulation software (such as Ansys, Comsol, HFSS, etc.), and in the case of simpler configurations, can even be derived intuitively (based on field experience) or theoretically. Once the ceramic refractory powder and core materia...

Embodiment 1

[0283] A preparation method of ultra-light glass foam with periodic porous pores:

[0284] Ceramic powder composition: low-temperature sintered ceramic mixed powder (LTCC, mainly Al, Si, B\mainly alumina, boron, silicon dioxide, may also add magnesium, cobalt, nickel or selenium);

[0285] Core material: PP (polypropylene) core with circular unit cells;

[0286] Ethanol (C 2 h 6 O) and methyl ethyl ketone (MEK) mass ratio is the solution of 70:30, and both are mixed. Divide low-temperature sintered ceramic mixed powder (LTCC, mainly Al, Si, B\mainly alumina, boron, silicon dioxide, and possibly magnesium, cobalt, nickel or selenium) with a sintering temperature of 800-900 °C into two Step addition: first add 31.35g powder and mix, then add 187.44g and mix. 218.79 g powder was prepared in 108.48 g ethanol / MEK solution.

[0287] In the first compound, 10.76 g of PVB (polybutyral C 8 h 14 o 2 ). The solution contained 25 parts PVB, 125 parts (MEK / ethanol solution). Typi...

Embodiment 2

[0296] A kind of preparation method of dense glass (LTCC ceramics) of honeycomb porosity:

[0297] Ceramic powder composition: low temperature sintered ceramic mixed powder (LTCC);

[0298] Core material: epoxy resin core of honeycomb unit cell;

[0299] 20g LTCC glass powder, 2% PAA, 70:30 ethanol and MEK solution (2% PVB), mixed.

[0300] Add ceramic powder, dispersant and other fillers to the honeycomb core when a certain uniform water-based consistency is obtained. The ceramic slurry is allowed to dry and then compressed. Sintering process:

[0301] 1. 5°C / min, reach 50% sintering temperature (400°C) within 4 hours, burn core and remove gas;

[0302] 2. Maintain a stable temperature at 500°C for 1 hour to remove all gas in the sample;

[0303] 3. Rise to 800°C and reach the final temperature within 3 hours;

[0304] 4. Stabilize at 800°C for 2 hours, then cool.

[0305] A dense glass with cellular porosity was obtained.

Abstract

The invention discloses multifunctional ceramic and a manufacturing method and application thereof. The multifunctional ceramic comprises a traditional ceramic material and a core material, wherein the core material can be any material with a cellular structure, a cellular structure with any shape and size and a cellular structure with different cell wall thicknesses, the prepared multifunctionalceramic is a ceramic body with a periodic cellular structure, unit cells are periodically arranged, the core material can also be a material without periodic cells, and characteristics of the multi-functional ceramic are combinations of characteristics used to create their original materials that are selected in consideration of the particular properties required for the final material. The invention further discloses the manufacturing method of the multifunctional ceramic, and compared with a traditional preparation process, the manufacturing method comprises additional steps determined by selection of the core material and the ceramic body material. A performance enhancing material can be prepared, and a new material with additional functions can also be prepared. The invention also discloses the application of the multifunctional ceramic.

Description

technical field [0001] The invention relates to a ceramic and its manufacturing method and application, belonging to the fields of ceramic materials and multifunctional materials, and in particular to a multifunctional ceramic and its manufacturing method and application. Background technique [0002] Technology 1 High Impact Strength Material Technology and Fragment Confinement [0003] Due to their excellent compression and impact strength, ceramic materials are widely used in ballistic / shock and general high-speed impact protection materials and systems, especially in the field of protection technology, including products for helmets, ballistic jackets, for space vehicles / satellite applications / aviation Armors and materials for applications / marine applications etc. up to extreme impact conditions or compression and high temperatures. In this case, reinforced ceramics and ceramic layered systems are commonly used (Ep0287918a1, US2009 / 0114083). [0004] In ballistic prote...
