Sažetak
Polyurethane (PU) foams are widely used as core materials for sandwich structures as insulating systems, in construction, marine application, etc. An important part of the sandwich structure is the core, which usually carries shear loads. Choosing a reliable test method and knowing the exact shear properties of the core used in structural design is useful for engineering practice. The shear properties of the core can be determined by several test methods described in ASTM C273 [1] and ISO 1922 [2] standards. Determination of shear properties of PVC foam according to ASTM C273 standard and using DIC technology is described in [3]. This paper aims to present the ISO 1922 standard test method used to determine the PU foam core shear modulus using two procedures of measuring the displacements, in a standard known as Procedure A and B. While Procedure A is only recommended for obtaining shear strength, Procedure B is recommended for obtaining shear modulus using extensometers. The aim of this paper is to determine the influence of the accuracy of displacement measurement obtained by Procedure A and B on the shear modulus of PU foam.
