Abstract
Provided is a honeycomb core material. The honeycomb core material is formed by welding a plurality of honeycomb corrugated bands, and includes a plurality of honeycomb elements. The honeycomb corrugated band includes free edges (1) and node edges (2) that are continuously arranged. The node edges that are correspondingly welded together form a honeycomb element node, and honeycomb element nodes are welded by laser or resistance spot welding. Welding spots of spot welding are uniformly distributed, a distance between two adjacent welding spots in a direction perpendicular to a cross section of the honeycomb element is d, a side length at the honeycomb element node is A, and a value of d is less than or equal to a value of A.
