Abstract

The invention provides a preparing method for a novel light high-strength protection armor plate. The armor plate is of a multi-layer sandwich biscuit type composite structure. The middle of the composite structure is connected with unilateral interlayer metal plates with different materials and thickness through thermal diffusion. The preparing method for the armor plate comprises the steps that firstly, raw materials are mixed; secondly, a bag sleeve for powder containing is prepared; thirdly, sample mixed powder is placed in the prepared bag sleeve; fourthly, physical powder sintering and metal plate thermal diffusion connection are carried out; fifthly, the solid solution heat treatment is carried out; and sixthly, aging thermal treatment is carried out. The armor plate is suitable for a bulletproof armor layer adopted by light armored cars and gunships for resisting the attack of light weapons and anti-equipment weapons and a preparing method for the armor plate.

Description

technical field [0001] The invention relates to a bulletproof equipment plate, in particular to a preparation method of a novel lightweight high-strength protective armor plate. Background technique [0002] my country's light armored vehicles have always used steel bulletproof armor, and armed helicopters have used titanium alloy bulletproof armor. However, future warfare will put forward higher and higher requirements for the army's long-range projection capability and the payload capability of armed helicopters, which puts forward strict requirements on the weight of equipment, making the steel armor and titanium alloy armor previously used It can no longer meet the needs of future weapons and equipment development. Therefore need to provide a kind of low density, good bulletproof effect, anti-shock, low cost, easy mass production, be applicable to the technical scheme of the armor plate of light armored vehicle and armed helicopter resist light weapon and anti-materiel ...
