Young’s Modulus and Poisson’s Ratio of Polyurethane Adhesive in Lightweight Floor System


The Lightweight Floor System with aluminum foil (LFS-L) has high thermal efficiency and meets the conditions of comfortable use. With this in mind, research work in the field of civil engineering began, which resulted in the development of an original lightweight technical solution for the heating floor. The layer connecting floor tiles with aluminum foil, which dissipates heat in LFS-L is polyurethane adhesive. To develop a computational model for a lightweight floor without screeds was appointed the strength indicators of this adhesive, such as Young’s modulus and Poisson’s ratio, which are not available in the literature. They were determined using tensile strength tests of polyurethane adhesive.
