A method of producing a panel comprises the following steps: - placing an assembly comprising core elements and impregnatable material webs extending along and between the core elements on a mould, which assembly comprises a first side and a second side which is situated opposite the first side, - enclosing said assembly under a cover layer in a sealing manner with respect to the mould, - introducing at least one inlet for injection material, which inlet ends at a first side of the assembly, - connecting the space which is enclosed by the cover layer and the mould to a discharge, - injecting injection material via the inlet on said first side of the assembly and causing the injection material to move along via the paths formed by the material webs between the core elements, - discharging air and/or gas from the enclosed space via the discharge by means of under pressure at a position which is at a different level to the position where the inlet ends.

SANDWICH PANEL AND METHOD FOR PRODUCING SUCH A PANEL
A panel possessing mutually averted panel surfaces and a periphery which delimits the panel surfaces is made up of a series of elongated core elements positioned parallel to one another, as well as material strips which are affixed to the core elements and which each extend between respectively two neighboring core elements and along both panel surfaces. Such a panel can expediently be constructed by placing a number of core elements and strips of flexible material side by side, or by stacking these one upon the other.
