Abstract

The preparation method of a ceramic bullet-proof plate provided by the present invention is to use a solvent-based adhesive to bond bullet-proof ceramic sheets and high-performance fiber laminates together through a negative pressure forming process, and then press and shape the bullet-proof plate in a special mold. The specific preparation method is as follows: firstly, the bulletproof ceramic sheet is neatly placed on a high-performance fiber fabric laminate coated with a solvent-based adhesive according to the designed shape; then, the ceramic sheet and the laminate are placed horizontally on a negative pressure forming machine ( The forming machine is used to form a negative pressure in a certain space), adjust the air pressure to 0.1-0.5 atmospheres, keep it for 5-10 minutes, then take it out, and manually adjust the displacement of the bulletproof ceramic sheet; finally, press and shape it in the mold, The molding condition is 0.3~1Mpa pressure at room temperature for 12 hours.

Description

technical field

[0001] The invention belongs to a forming method and process of bulletproof ceramics, and relates to a hard bulletproof plate used in the field of personal protection and armor, which is used to protect bullets with high penetrating power fired by light weapons with bullet speeds above 700m / s. Background technique

[0002] The general ceramic bulletproof plate is mainly used in the field of human body protection and armor of tanks and aircraft. The former is inserted in the front and rear pockets of the bulletproof vest, and the latter protects the key parts of the vehicle, aircraft seats, and fuel tanks. It is made of High-hardness bulletproof ceramics and high-performance fiber fabrics are laminated with adhesives.

[0003] At present, the composite method of bulletproof ceramics and fiber fabric laminates is to use thermosetting adhesives, such as modified phenolic resins, modified epoxy resins, etc., to be composited at one time under hot pressing conditi...
