Porous beam structure

摘要

The porous structure (1) comprises beam-shaped elements (3, 3', 3'', 3''',6', 6'', 6''', 6''''), which consist of linearly passing beam-shaped elements and curved beam-shaped elements. A distance of the beam-shaped elements and/or a thickness of the beam-shaped elements vary in a plane. The distance and/or the thickness and/or a height of the beam-shaped elements vary in the plane opposite to a lower layer. The beam-shaped elements: are rectangular in cross-section; and pass the plane directly over the beam-shaped elements of preprocessing elements.

The beam-shaped elements: are rectangular in cross-section; pass the plane directly over the beam-shaped elements of preprocessing elements; pass the plane between the beam-shaped elements of the preprocessing elements; and consist of a metal and ceramics. The porous structure has locally different porosities at different places on a surface, and a porosity gradient in vertical direction. An independent claim is included for a method for producing porous structure.
