Abstract
The present invention relates to a process for the production of a composite article comprising a structured porous body (PB) and a particle foam (PF), wherein the provided structured porous body (PB) is inserted into a mould (M) and the mould (M) is filled with expanded foam beads (EFB) so that the expanded foam beads (EFB) are in contact with each other and the structured porous body (PB) is at least partially in contact with the expanded foam beads (EFB). Then, the expanded foam beads (EFB) are thermally welded, wherein the particle foam (PF) is built and the composite article is obtained. Moreover, the present invention relates to a composite article obtained by this process, as well as to a composite article comprising a structured porous body (PB) and a particle foam (PF). The present invention further relates to the use of the inventive composite articles in the shoe industry, in the sports and leisure sector, in vehicle construction, in the medical sector, in mechanical engineering and in the logistics sector. Furthermore, the present invention relates to a composite article comprising a structured porous body (PB) and a foam (F), wherein the structured porous body (PB) and the foam (F) comprise the same polymer (P).
