Abstract

The subject of this paper is to determine the idealised stress-strain diagram (primal curve) as well as a numerical expression of a straight line and a parabolic curve for glass fibre reinforced polymers (GFRP). The intention is to create a tool, by which one could define the stress-strain diagram for any given glass fibre based on tensile strength. GFRP is a material that is increasingly being used in structures. Because of that we need to know some of its basic characteristics or of other similar composite materials, so as to be able to calculate these structures. This paper presents the modulus of elasticity determined by testing glass fibre reinforced polymer samples and a proposition of an idealised stress-strain diagram as well as a numerical determination of the modulus.
