Abstract

The invention discloses a manufacturing method of a yawing composite ceramic bulletproof plate. The manufacturing method comprises the following steps that (1) an organic or inorganic light material is selected to restrain a ceramic ball to form a light yawing layer; (2) a material of the ceramic ball is selected; (3) a yawing unit is prepared; (4) the ceramic bulletproof plate is prepared; (5) aback plate is prepared; and (6) compression molding forming is conducted. According to the manufacturing method, by ingeniously restraining the ceramic ball, when being shot into the composite bulletproof plate, a bullet makes contact with the ceramic ball firstly, the running trajectory of the bullet is changed through the circular-arc surface of the ceramic ball and the light material, thus thebullet vertically shot into the bulletproof plate is yawed, the kinetic energy component of the bullet striking the bulletproof plate is lowered, and the bulletproof capacity of the bulletproof plateis improved; and according to the yawing composite bulletproof plate manufactured through the method, the bulletproof property of the bulletproof plate is improved, the surface density is lowered, andthe bulletproof plate is suitable for substituting an existing bulletproof armor.

Description

technical field [0001] The invention belongs to the technical field of composite ceramics, and in particular relates to a method for manufacturing a yaw composite ceramic bulletproof plate. Background technique [0002] With the continuous update of weapons and equipment, the speed of various kinetic energy bullets and the performance of armor-piercing materials have been continuously improved, which puts forward higher requirements for bulletproof materials and bulletproof structures. The bulletproof plate made of a single bulletproof material can no longer satisfy the blocking of kinetic energy bullets. It is quite difficult to reduce the surface density and ensure the bulletproof requirements of land or aviation equipment with a single structure bulletproof plate. The invention uses ceramic balls constrained by light materials to play a yaw effect on the incident bullets, so that the kinetic energy component of the bullets acting on the ceramic bulletproof plate is reduc...
