Problems solved by technology

[0003] Although boron carbide has excellent properties such as high hardness, high strength, high elastic modulus, and low density, its bending strength and fracture toughness are low, and its brittleness is large, so its ability to resist multiple bullets is poor.

Abstract

The invention provides a ceramic-based composite material capable of defensing 12.7mm armor piercing incendiary. The material comprises a polyurea layer, an aramid fiber layer, a ceramic layer and a PE layer, wherein the aramid fiber layer, the ceramic layer and the PE layer are sequentially arranged from top to bottom and are bonded together through a bonding agent to form a middle layer; the polyurea layer is sprayed and coated at the upper surface and the lower surface of the middle layer; the thickness of the polyurea layer is 0.5mm; the thickness of the aramid fiber layer is 1mm; the thickness of the ceramic layer is 15mm; the thickness of the PE layer is 18mm.

Description

technical field [0001] The invention belongs to the field of ceramic materials, in particular to a ceramic-based composite material capable of defending against 12.7mm armor-piercing incendiary bombs. Background technique [0002] At present, the demand for helicopter bulletproof is constantly increasing at home and abroad, and the aircraft is required to be equipped with armor materials that can resist various caliber bullets. At the same time, due to the limitation of weight load, higher requirements are put forward for the weight reduction of lightweight bulletproof armor. The smaller the surface density, the better. Advanced ceramic materials have gradually become the mainstream in the field of bulletproof materials due to their high hardness, relatively low density, and high bulletproof performance. The three most widely used ceramics are alumina, silicon carbide, and boron carbide. Boron has the highest hardness and lightest density among the three ceramic materials, m...
