CERAMIC-POLYMER COMPOSITE BODY, METHOD FOR ITS MANUFACTURE AND TERMINAL Russian patent published in 2023 - IPC B29C45/14 H05K5/00 H04M1/02 

FIELD: composites.

SUBSTANCE: group of inventions can be used in the manufacture of a mobile phone, tablet computer or laptop case. The ceramic-polymer composite body comprises a ceramic element and a polymer element moulded on the ceramic element by injection moulding. The surface related to the ceramic element and connected to the polymer element comprises a plurality of holes in the form of strips extending from this surface into the interior of the ceramic element. The strip-shaped apertures are open apertures whose pore sizes are between 700 nm and 500 mcm and at least some of the apertures are greater than 100 mcm and less than or equal to 1000 mcm in length. Holes in the form of strips are filled with a polymeric material. A layer of nitrogen compound is attached to the inside walls of the holes, which reacts exothermically with the liquid resin penetrating the strip-shaped holes to provide heat to keep the front end of the liquid resin flowing continuously. A method for manufacturing a ceramic-polymer composite body, a terminal and a mobile phone are also proposed.

EFFECT: group of inventions makes it possible to increase the adhesion strength of ceramic and polymeric materials in a ceramic-polymer composite.
