Embodiment Construction

[0039] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0040] like figure 1 , figure 2 , image 3 , Figure 4 As shown, an integral silicon carbide ceramic bullet-proof plate of the present invention includes an integral bullet-proof plate body 1 that can be bonded to an adhesive backing plate. The bullet-proof plate body 1 is composed of several curved surfaces. The convex arc surface of the plate body 1 is provided with several relief grooves 1.2 which divide the bulletproof plate body 1 into a plurality of unit blocks 1.1.

[0041] There is a distance between each crack relief groove 1.2 and the side of the bulletproof plate body 1 , that is, the crack relief groove 1.2 and the side that does not reach the bulletproof plate body 1 , thereby affecting the entire bulletproof plate body 1 .

[0042] The unit block 1.1 may be one or a combination of circles, ellipses, rectangles and polygons. ...

Abstract

The invention discloses an integral type silicon carbide ceramic elasticity-proof plate which comprises an integral type elasticity-proof plate body (1) which can be attached to an adhesion back plate. The elasticity-proof plate body (1) is composed of a plurality of curved faces. The integral type silicon carbide ceramic elasticity-proof plate is characterized in that the outer convex arc face of the elasticity-proof plate body (1) is provided with a plurality of crack arrest grooves (1.2) which divide the elasticity-proof plate body (1) into a plurality of unit blocks (1.1). The integral type silicon carbide ceramic elasticity-proof plate has the elasticity-proof effect of both the integral type elasticity-proof plate and small block elasticity-proof plates, and is relatively low in cost under the condition of the same thickness. The invention further discloses a manufacturing method of the integral type silicon carbide ceramic elasticity-proof plate. According to the method, continuous production is achieved, repeatability is good, production efficiency is high, deformation is small in plate drying process and sintering process after molding, and the elasticity-proof performance is good.

Description

technical field [0001] The invention belongs to the field of protective equipment made of ceramic products, in particular to an integral silicon carbide ceramic bulletproof plate and a manufacturing method thereof. Background technique [0002] Body armor is commonly used protective equipment for soldiers, policemen, security guards and other special staff and other personnel in special environments. Its main purpose is to effectively prevent gunshots and ensure the safety of personnel. Bulletproof vests are generally composed of bulletproof panels, bonded back panels and bulletproof fiber materials. The bulletproof plate as the main body of the bulletproof has been developed from the past hard metal panel and polymer material panel to the ceramic material panel. Ceramic material panels are mainly made of alumina, silicon carbide, boron carbide and other composite ceramic materials [0003] At present, the commonly used ceramic bulletproof panels are commonly used in two t...
