Foamed aluminum automobile anti-explosion oil tank

Abstract

The invention discloses a foamed aluminum automobile anti-explosion oil tank. The main technical scheme of the foamed aluminum automobile anti-explosion oil tank is that the wall of an automobile oil tank is made into a sandwich structure, and a foamed aluminum layer (1) is formed by filling a space between two layers of steel plates (2) with a novel foamed aluminum material. According to the foamed aluminum automobile anti-explosion oil tank disclosed by the invention, a foamed aluminum layer sandwich structure has the characteristics that the mass is light, the specific stiffness is high, good vibration damping (damping) performance is obtained, the action of slowing down explosive shock waves is obtained when fuel in the inner part of the oil tank is exploded, the damage to surrounding people or articles due to the explosion is reduced or is even prevented, in addition, the oil tank can be prevented from being subjected to gun shooting when the oil tank is used on a military vehicle, and the safety performance of the military vehicle is increased.

Description

Technical field: [0001] The invention relates to an automobile explosion-proof fuel tank, in particular to an automobile explosion-proof fuel tank made of aluminum foam. Background technique: [0002] Porous metal foam is composed of metal skeleton and pores, and is a functional material developed in recent decades. Since its inception, as a structural material, it has the characteristics of light weight and high specific strength; as a functional material, it has many physical properties such as porous, vibration reduction, damping, sound absorption, sound insulation, heat dissipation, impact energy absorption, electromagnetic shielding, etc. In addition to its recyclable characteristics, it adapts to the needs of current development and has been more and more widely used in general industrial fields and high-tech fields at home and abroad. The porous metal foam materials that have been developed so far include foamed aluminum (and foamed aluminum alloy), foamed nickel...

AI Technical Summary

Problems solved by technology

[0004] The fuel tank of a car is a container for fuel. If an accident occurs in the car and the fuel tank ruptures, the fuel will flow out. In this case, if a fire is accidentally caused, the fuel tank will easily explode.

In addition, for some special military vehicles, if the fuel tank is shot and a large amount of fuel leaks, this situation will easily affect the escape of the vehicle, and it is not suitable to get out of the vehicle to repair the fuel tank in complicated and dangerous situations.
