Abstract

In a process for fabricating a panel with a corrugated core, a filling material in liquid state is introduced into the corrugations of a sandwich panel, the resin is hardened by cooling and the panel formed as for a plane panel. The fusion point of the filler is chosen so that in conjuction with base material, an assembly with optimum mechanical properties is obtained. The liquid is pref. an aq. compsn. which can be solidified by a cooling bath such as liquid N2 at -196 degrees C. Austenitic stainless steel of the class Z 12CN 18-8 may be used for the corrugations. After fabrication the filling liquid is removed. The sandwich materials have a wide range of plasticity in the solid state and can be simply and economically formed.
