Abstract (en)
A core (200) is disclosed, formed as a three dimensional body presenting a first face (201) upon which a facing sheet (320) is attachable. The core (200) comprises a wall structure defining a plurality of channels (202), each having a longitudinal axis (203) intersecting the first face (201) at an angle (±) thereto. The angle (±) is less than 90 degrees. A board formed from such a core is also disclosed, as well as a block of material for providing the core. Methods for producing the block of material, the core and the board are also disclosed.
