Abstract

The invention provides a preparation method for a novel light-weight and high-strength protection armor plate. The armor plate material is of a multi-layer sandwich biscuit type composite structure. The middle of the composite structure is connected with single-edge interlayer metal plates of different materials and thicknesses through thermal diffusion. The preparation method for the armor plate includes the steps that firstly, raw materials are mixed; secondly, bag covers used for containing powder are prepared; thirdly, sample mixed powder is contained in the prepared bag covers; fourthly, powder physical sintering and metal plate thermal diffusion connection are conducted; fifthly, solid solution heat treatment is conducted; and sixthly, ageing thermal treatment is conducted. The preparation method is suitable for bulletproof armor layers adopted for attacks of fighting light arms such as light armored cars and gunships and anti-material weapons, and production and preparation of the bulletproof armor layers.

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 ...
