Foamed aluminum ribbed sandwich panel

Abstract

The invention discloses a foamed aluminum ribbed sandwich panel which comprises two aluminum panels, at least one foamed aluminum and at least one rib, wherein the at least one rib and at least one foamed aluminum are adhered to form a foamed aluminum sandwich structure of which the shape and size are completely the same as those of the cross section of each aluminum panel; the at least one rib is perpendicular to the top surface and bottom surface of the foamed aluminum sandwich structure; and the two aluminum panels comprise an upper aluminum panel and a lower aluminum panel and are respectively adhered to the top surface and the bottom surface of the foamed aluminum sandwich layer. The foamed aluminum ribbed sandwich panel with the structure is applied to serve as an energy absorption buffer device for bearing impact loads which are uniformly distributed and has the advantage of high energy absorption efficiency.

Description

technical field [0001] The invention relates to a foamed aluminum composite plate structure, in particular to a foamed aluminum ribbed sandwich panel. Background technique [0002] Aluminum foam is a good energy-absorbing material, and its application has covered automobile anti-shock shields, aircraft landing gear, elevator safety pads, high-speed grinding machine protective cover energy-absorbing linings, etc. At present, the common foamed aluminum composite plate structure is the foamed aluminum sandwich panel, etc., which not only exerts the characteristics of the foamed aluminum material but also utilizes the advantages of the high strength of the metal panel, and has excellent performance when subjected to local loading and dynamic penetration loading. Energy absorption effect. However, in addition to the above loading conditions, in engineering practice and daily life, many structures are also vulnerable to damage caused by uniform impact loads. For example, the forc...

Problems solved by technology

[0003] In order to overcome the deficiency of low energy absorption efficiency when the aluminum foam composite plate used as an energy-absorbing buffer device is under the action of a uniform impact load in the prior art, the present invention proposes a foamed aluminum ribbed sandwich panel, which has the same structure as Compared with the aluminum foam sandwich panel with the same cross-section height, the energy absorption is greatly increased when it bears the uniform impact load, which effectively improves the protection effect
