Fiber/ceramic/metal composite material bulletproof plate and manufacturing method thereof

Abstract

The invention discloses a fiber / ceramic / metal composite material bulletproof plate and a manufacturing method of the fiber / ceramic / metal composite material bulletproof plate. The fiber / ceramic / metal composite material bulletproof plate is characterized in that the bulletproof plate comprises at least one metal lateral restraint resin composite plate, and a fiber layer, a ceramic layer and the metal lateral restraint resin composite plate form a sandwich structure. The manufacturing method includes the steps of manufacturing a titanium alloy frame through laser welding, manufacturing an ultra-high molecular weight polyethylene plate according to the size of a titanium alloy cavity, fixing the ultra-high molecular weight polyethylene plate into the cavity of the titanium alloy frame through adhesives, connecting a carbon fiber layer with the ceramic layer through adhesives, and connecting the ceramic layer with the metal lateral restraint resin composite plate through a ceramic surface metallization method. The bulletproof plate is high in rigidity, good in tenacity and good in tear resistance, the problems that the phenomenon that the layers are separated due to vibration happening when the bulletproof plate is impacted occurs, and the metal can not play a good role in resisting bullets when directly serving as a bullet bearing face are solved, and the bulletproof performance of the bulletproof plate is improved. The fiber / ceramic / metal composite material bulletproof plate can be widely applied to armored cars and aircrafts which need to be protected.

Description

Technical field: [0001] The invention relates to a preparation method of a composite bulletproof plate, in particular to a fiber / ceramic / metal composite bulletproof plate and a preparation method thereof. Background technique: [0002] There are mainly three types of existing bulletproof plates. The first type is alloy steel bulletproof plate, which has good toughness but low hardness. The second type is ceramic bulletproof plate, which has low density and high hardness, but has poor impact resistance and is easily broken. The third type is metal / ceramic laminated composite bulletproof plate. The strength of the combination of metal plate and ceramic plate is low, and the effect of absorbing projectile energy is not ideal under the impact of high-speed projectiles. [0003] The traditional laminated composite bulletproof plate usually uses a relatively hard ceramic as the front plate and a tough metal or fiber composite material as the back plate, and the two are bonded wit...
