Abstract:
The invention relates to a method of manufacturing a sandwich panel comprises the steps of: a) providing a plate-shaped assembly of a first cover part and a second cover part and between these cover parts a core part of a thermoplastic material containing a physical blowing agent, b) heating the assembly resulting from step a) under pressure between press tools in a press to a foaming temperature below the glass transition temperature of the thermoplastic material in the core part, thereby effecting adhesion of the foamed core part to the first and second cover parts c) foaming the thermoplastic material in the core part under pressure and at the foaming temperature wherein the spacing between the press tools is increased; d) a cooling step of cooling the foamed sandwich panel resulting from step c), while the sandwich panel is maintained under pressure between the press tools; e) removing the thus cooled sandwich panel from the press; and f) drying the sandwich panel thus obtained;   wherein the cooling step d) comprises.a first substep d1) of cooling the foamed assembly from the foaming temperature to an intermediate temperature in the range of 70-100° C. at a first cooling rate and a second substep d2) of cooling the foamed assembly from the intermediate temperature to ambient temperature at a second cooling rate, the second cooling rate is less than the first cooling rate.

Claim (Index 9):
Method according to  claim 8 , wherein the thermoplastic of a cover part is selected from the group consisting of polyetherimide (PEI), polyethersulfone (PES), polyphenylsulfone (PPSU) and polysulfone (PSU).
