Arched composite alloy protection plate module and production technology thereof

Abstract

The invention belongs to the technical field of vehicle protection, and relates to an arched composite alloy protection plate module and a production technology thereof. The arched composite alloy protection plate module is arched and mainly composed of metal matrixes and a metal mesh, and the metal mesh is composited in the metal matrixes. The arched composite alloy protection plate module is produced with an FV casting technology. The production technology includes the steps: (1) producing a full mold, and using polystyrene foam beads for forming a protection plate template by foaming; (2) coating the template of the protection plate module with fireproof paint, and after drying, placing the dried template into a vacuum casting box for vacuumizing prior to molding by casting; (3) subjecting the arched composite alloy protection plate module molded by casting to heat treatment, and sequentially performing annealing, normalizing and tempering. Vehicle bodies are sufficiently protected against damage caused by shock waves of explosive, personal safety of passengers is protected sufficiently and effectively, and particularly effect in protecting against the explosive less than 10 kilos is better.

Description

technical field [0001] The invention belongs to the technical field of vehicle protection, and in particular relates to an arched composite alloy guard plate module and a production process thereof, which are used for bottom protection of wheeled vehicles, especially for bottom protection of wheeled armored vehicles. Background technique [0002] Since the beginning of the new century, asymmetric low-intensity warfare such as anti-terrorist wars and anti-insurgency has made wheeled vehicles, especially wheeled armored vehicles, the main tool for transporting soldiers. Normally, the bottom of an ordinary wheeled vehicle is parallel to the ground, which cannot decompose and absorb the energy of the shock wave generated when the explosive explodes. The shock wave of the explosion will cause damage to the vehicle body and casualties of the occupants. All over the world, the threat from landmines, roadside bomb attacks is increasing, and the casualties are increasing. In this re...

AI Technical Summary

Problems solved by technology

This kind of structural design decomposes the damage to the bottom of the car body caused by the shock wave of the mine explosion, but there are still three disadvantages: one is that the metal energy absorbing components inside the bottom part absorb less energy and cannot prevent the fragments of the guard plate from being damaged. Spraying and avalanche cannot sufficiently resist the damage to the car body caused by the shock wave of explosives, and cannot effectively protect the personal safety of the occupants; the second is that the V-shaped bottom is a whole, the production process is difficult, and it is inconvenient to disassemble and repair. When replacing, the required material is huge and the cost is high; the third is that the distance between the V-shaped sharp point of the V-shaped bottom and the ground is small, and it often collides with the ground, especially in rough road conditions, which affects the driving of the vehicle.
