Abstract

During the process of manufacturing the prosthesis sockets in the lamination process, a chemical reaction occurs between the mixture of materials used in the lamination process after being placed inside a mold covered with layers of PVA, Perlon stockinet and with the existence of materials to strengthen the socket or not. This chemical reaction causes the emission of heat from within the sample. The emission continues until the sample is cooled by natural convection, which lasts for 30 minutes or less depending on the amount of hardener material used in the laminating process. The current work focused on observing the thermal distribution occurring on the surface of the hot sample during the cooling period, in order to see areas with high thermal concentration from other regions. Then put the thermal gradient map for the whole sample that helps to understand thermal stress which is used to evaluate the stresses induced by some thermal load, which is in the form of thermal images that's taken by using a thermal camera known as FLIR i7, which shows thermal distribution on each side of the sample. For more results, three molds were made for different levels of amputation (above knee amputation (AK), below knee amputation (BK) and Syme amputation. Then use the thermal camera to obtain thermal distribution images for each sample.
