Embodiment 1

[0049] An anti-collision strip for an automobile body, the core of which is a particle-reinforced foamed aluminum-based composite material, the core is wrapped with an elastic material layer, and the outer layer of the elastic material is a rectangular steel pipe, which is characterized in that:

[0050] The particle-reinforced foamed aluminum-based composite material is prepared by the following preparation method:

[0051] Prepare an aluminum alloy ingot, its composition percentage is: Mg6﹪, Si1﹪, Sn0.6﹪, Cr0.35﹪, Fe0.65﹪, Ce1.3﹪, Y0.6﹪, Mn0.1﹪, the balance is Al ;

[0052] Melt the above-mentioned aluminum alloy and raise the temperature to 700°C-760°C, pass through protective Ar gas to refine and keep it warm for 10 minutes;

[0053] Add thickener accounting for 6-7% of the total weight of the melt and add silicon carbide and / or alumina particles accounting for 10-12% of the mass fraction of the melt, stir the molten metal at a speed of 500-800rpm for 2-3 minutes, and the...

Abstract

Disclosed is a bumper strip for an automotive body. The core portion of the bumper strip is a particulate reinforced aluminum foam matrix composite and is wrapped with an elastic material layer, and a rectangular steel tube is arranged outside the elastic material layer. An iron-base alloy material fully meets the requirement for external strength. By the adoption of aluminum-base alloy, it is better guaranteed that the impact resistance of the product is higher, and meanwhile product quality is improved.

Description

technical field [0001] The invention relates to an anti-collision strip for an automobile body, belonging to the technical field of auto parts. Background technique [0002] When we drive daily, we will inevitably encounter small scratches and bumps, which will seriously affect the body of our car. If we don’t go out for a long time, it is easy to rust. In order to protect our car models, many car owners Began to install car anti-collision strips for cars, which are also called protective strips, anti-scratch strips, etc. Prevent the side of the car body from being scratched or bruised by foreign objects, and play a protective role. The existing anti-collision strip has complicated processing technology and poor anti-collision effect. Contents of the invention [0003] An anti-collision strip for an automobile body, the core of which is a particle-reinforced foamed aluminum-based composite material, the core is wrapped with an elastic material layer, and the outer layer ...
