Composite honeycomb material

Abstract

The invention relates to a composite honeycomb material which comprises a plurality of honeycomb plate bodies and a plurality of partition plates, a layer of honeycomb plate body is laid on each partition plate to form a composite group, and a plurality of composite groups are sequentially stacked; the honeycomb plate body is of a Miura folded structure, when each honeycomb plate body is laid on the corresponding partition plate, the top and the bottom of the honeycomb plate body are connected with the adjacent partition plate, namely, the honeycomb plate body is communicated with the corresponding partition plate, and airflow flows in the honeycomb plate body; according to the invention, the number and angle of the laying layers can be adjusted according to the stress condition, the design space is large, the Miura folded structure is adopted, and the composite honeycomb material has good in-plane shear resistance, in-plane isotropy, deformability and connectivity, so that the corrosion resistance and energy dissipation capacity of the composite honeycomb material are improved.

Description

technical field [0001] The invention relates to a composite honeycomb material, belonging to the technical field of honeycomb panels. Background technique [0002] Honeycomb panels are widely used in construction, shipbuilding, aerospace and other fields due to their good environmental performance and cushioning performance. Traditional honeycomb panels mostly adopt regular hexahedral honeycomb lattice structure, which is more beautiful and has excellent performance. [0003] The honeycomb panel is an anisotropic material, and its coplanar bearing capacity is much lower than that of the different plane, which makes the traditional honeycomb panel unable to withstand large in-plane impact loads, and the bearing capacity of traditional honeycombs in the plane is different. , which greatly limits the application range of honeycomb panels. In addition, the traditional honeycomb panels are closed, and corrosion often occurs inside the honeycomb panels due to moisture condensati...

AI Technical Summary

Problems solved by technology

[0003] The honeycomb panel is an anisotropic material, and its coplanar bearing capacity is much lower than that of the different plane, which makes the traditional honeycomb panel unable to withstand large in-plane impact loads, and the bearing capacity of traditional honeycombs in the plane is different. , which greatly limits the application range of honeycomb panels

In addition, traditional honeycomb panels are closed, and in actual use, corrosion often occurs inside the honeycomb panel due to water vapor condensation, which greatly reduces the service life of the honeycomb panel

Therefore, it is imminent to improve the in-plane isotropy, shear resistance and corrosion resistance of honeycomb panels. However, it is very difficult to improve the performance of honeycomb panels without changing the structure and materials of traditional honeycomb panels.
