Lightweight multidirectional buffer energy-absorbing structure of stainless steel ultra-thin strip and preparation method of lightweight multidirectional buffer energy-absorbing structure

Abstract

The invention provides a lightweight multidirectional buffering energy-absorbing structure of a stainless steel ultra-thin strip and a preparation method, the lightweight multidirectional buffering energy-absorbing structure comprises a honeycomb sandwich structure, panel structures are arranged on the upper surface and the lower surface of the honeycomb sandwich structure, and each panel structure comprises a plurality of single-layer corrugated boards; the arrangement directions of the corrugated groove layers in the upper single-layer corrugated board and the lower single-layer corrugated board which are adjacent to each other are perpendicular to each other; the multidirectional buffering and energy-absorbing structure is provided with a bearing structure in each direction, and can resist impact, compression, bending and other load effects from different directions; meanwhile, a stainless steel ultra-thin strip is adopted as a main component material of the structure, and compared with an aramid paper honeycomb and aluminum honeycomb structure, the mechanical property is greatly improved, and the service temperature is greatly increased; in addition, by regulating and controlling the sizes of grooves in the honeycomb sandwich structure and the corrugated groove layer and selecting filling materials in the corrugated groove layer, the actual requirements of different protection structures can be met, and the designability is high; and finally, the selected ultra-thin stainless steel strip has good machinability, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the field of design and preparation of lightweight protective structures, in particular to a lightweight multi-directional buffer energy-absorbing structure of ultra-thin stainless steel strips and a preparation method thereof. Background technique [0002] The honeycomb sandwich composite material is usually a lightweight material with a composite structure formed by bonding fibers or metal panels on the upper and lower surfaces of the honeycomb core by using a bonding process. This kind of honeycomb sandwich composite material is widely used in wings, fuselage, empennage, aircraft floor, radar, etc. Covers, liquid hydrogen storage tanks and other aerospace vehicle structural components. [0003] In the panel manufacturing of honeycomb sandwich composite materials, different types of fibers or metal sheets are usually used as the component materials of the panel, and the corresponding resin glue is used for bonding and lamina...
