Mounting foams : Making of specimens and mechanical testing

Abstract

The article deals with the design of the technology of production of polyurethane foam (PU) specimens and with their mechanical testing. A simple procedure is proposed to produce specimens with complex shapes. The procedure is tested on two different mounting foams. These specimens were subjected to several experiments. The article presents experimental results for only one mounting foam. The tests were performed on a Testometric M500-50CT testing machine. Specifically, these are a tensile/compression test, a 3-point bending test, a shear test, and a modified indentation test. For each specimen, the displacement was also measured in the selected area with Digital Image Correlation Method. These measured data are presented in the article.
