Beschreibung
Zusammenfassung:	The invention relates to a material (1) with a sandwich-type structure to be thermocompressed, comprising a core (2) arranged between a first skin (3) and a second skin (4), said first skin (3) comprising a first polymer matrix (3a), said second skin (4) comprising a second polymer matrix (4a), characterised in that said core (2) comprises a third polymer matrix (2a), wherein a porosity agent (5) configured to create a porosity in the core (2) is distributed, such that when said material (1) is thermocompressed, the first (3a) and second (4a) polymer matrices adhere to the third polymer matrix (2a), and the porosity agent (5) is further configured to maintain or increase said porosity in the core (2) when said material (1) is thermocompressed.
