Title:
HONEYCOMB CORE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2023/000644
Kind Code:
A1
Abstract:
A honeycomb core material. The honeycomb core material is formed by means of welding a plurality of honeycomb corrugated bands, and comprises a plurality of honeycomb elements. The honeycomb corrugated band comprises free edges (1) and node edges (2), which are continuously arranged. The node edges, which are correspondingly welded together, form a honeycomb element node, and the honeycomb element nodes are welded by means of laser or resistance spot-welding. Welding spots of spot-welding are uniformly distributed, the distance between two adjacent welding spots in a direction perpendicular to the cross section of the honeycomb element is d, the length of an edge at the honeycomb element node is A, and the value of d is less than or equal to the value of A. The value of d is set to be less than or equal to that of A, such that it is ensured that there is support of at least one welding spot within progressive shrinkage deformation during the compression of honeycomb elements, cracking and distortion also do not occur even in the smallest unit inside a honeycomb core material during compression, instability does not occur in the smallest unit during honeycomb compression, and thus instability certainly does not occur in the whole honeycomb, thereby ensuring high stability of a whole crush curve of the honeycomb core material, and controlling and adjusting the crush strength and the fluctuation of the crush curve.
