Method for manufacturing an object, in particular an orthopaedic object (10, 10'), with an elastically compressible composite body (1, 1') having a plurality of elements (2, 2', 2"), comprising: - providing a first plate-shaped body of a first material, wherein the first material is expanded, wherein the first body has a first contact face, - providing a second plate-shaped body of a second material, wherein the second body has a second contact face, wherein the first and the second material each include a crosslinkable component comprising a crosslinkable polymer, wherein the crosslinkable polymer of the first body is in a partially crosslinked form, wherein the crosslinkable polymer of the second body is in a partially crosslinked form, wherein the first body is manufactured in that initially a first base material is manufactured, by mixing together the crosslinkable component in uncrosslinked form, a chemical blowing agent and a crosslinking agent, in that subsequently the chemical blowing agent and the crosslinking agent are activated in such a way that the base material expands and the crosslinkable polymer becomes partially crosslinked, so as to obtain the expanded material of the first body with partially crosslinked polymers, wherein the first body is softer than the second body, wherein the first body has a hardness between 5 and 50 Shore A, wherein the second body has a hardness between 20 and 75 Shore A, and - manufacturing the composite body (1, 1') with a durable connection between the first and the second body (3, 4), in that the first body and the second body are heated and the first contact face of the first body is brought into contact with the second contact face of the second body and held in contact for a period of time. - providing a first plate-shaped body of a first material, wherein the first material is expanded, wherein the first body has a first contact face, - providing a second plate-shaped body of a second material, wherein the second body has a second contact face, wherein the first and the second material each include a crosslinkable component comprising a crosslinkable polymer, wherein the crosslinkable polymer of the first body is in a partially crosslinked form, wherein the crosslinkable polymer of the second body is in a partially crosslinked form, wherein the first body is manufactured in that initially a first base material is manufactured, by mixing together the crosslinkable component in uncrosslinked form, a chemical blowing agent and a crosslinking agent, in that subsequently the chemical blowing agent and the crosslinking agent are activated in such a way that the base material expands and the crosslinkable polymer becomes partially crosslinked, so as to obtain the expanded material of the first body with partially crosslinked polymers, wherein the first body is softer than the second body, wherein the first body has a hardness between 5 and 50 Shore A, wherein the second body has a hardness between 20 and 75 Shore A, and - manufacturing the composite body (1, 1') with a durable connection between the first and the second body (3, 4), in that the first body and the second body are heated and the first contact face of the first body is brought into contact with the second contact face of the second body and held in contact for a period of time.
