A structural component is formed with an outer shell of sintered, solid, powder particles, and a porous core of sintered, hollow, bodies arranged in layers. The hollow bodies are of increased diameter in the layers in a direction from the outer periphery of the core towards the center of the core. T

A structural component is formed with an outer shell of sintered, solid, powder particles, and a porous core of sintered, hollow, bodies arranged in layers. The hollow bodies are of increased diameter in the layers in a direction from the outer periphery of the core towards the center of the core. The material of the outer shell and of the core is a metal or ceramic.

A structural component comprising an outer shell including external and internal shell portions spaced from one another in generally parallel relation, and a core within a space formed between said external and internal shell portions, said internal and external shell portions each being constituted of sintered, solid, powder particles, said core comprising sintered, hollow, bodies arranged in juxtaposed layers one on the next in approximately parallel relation between said internal and external shell portions, said hollow bodies having graduated increased diameters in said layers in a direction from an outer peripheral region of the core at said internal and external shell portions towards a center of the core, said hollow bodies in each of said layers being substantially of the same diameter and disposed in the respective layer approximately parallel to said internal and external shell portions.
