Abstract: The present invention relates to a polymer foam laminate structure (1), comprising—a first solid layer (101) having a density of more than 1000 g/l, which is covered by at least one first functional layer (103), —a polymeric foam layer (105) provided on the at least one first functional layer (103), —a second solid layer (109) having a density of more than 1000 g/l, which is covered by at least one second functional layer (107), the at least one second functional layer (107) being in contact with the polymeric foam layer (103), wherein the polymeric foam layer (105) has a density of 20 g/l to less than 1000 g/l. The present invention further pertains a method for preparing a polymer foam laminate structure (1) and a composite component (1000) inter alia comprising the polymer foam laminate structure (1).
