“…In recent years, research studies [4][5][6][7][8][9] have shown that the typical relationship between a mechanical property of a polymer composite and temperature under isothermal condition (that is, constant temperature throughout the material) is generally that shown in Figure 5. Since limited data exist on individual mechanical properties, such as modulus and strength, it is assumed for convenience that all mechanical properties can be fitted to the typical mechanical property versus temperature relationship shown in Figure 5.…”

“…The authors have, on the basis of previously published research on the high temperature performance of polymer composites [4,5,6,7,8,9], selected a sigmoid curve based on a hyperbolic tangent function [4,5,6] to describe the mechanical and bond property degradation of GFRP composites. In this study, was taken to be 1.0 because, based on TGA, the resins do not experience any significant amount of decomposition until 350°C and was the average of the observed values of the property at room temperature.…”

One of the greatest impediments to using fibre reinforced polymer (FRP) composites in buildings and parking garages is their susceptibility to degradation when exposed to elevated temperatures and the limited knowledge on the thermal and mechanical properties of these composites at such temperatures. Glass FRP (GFRP) tensile coupons and single lap-splice coupons were tested in tension to study the mechanical properties under steady-state and transient thermal conditions. Tests were conducted at a range of temperatures between room temperature and +200°C. In terms of tensile strength, approximately half of the strength of the FRP was lost near the glass transition temperature of the epoxy resin matrix. However, 40% of the room temperature strength of the GFRP was still retained at 200°C. The lap-splice tests showed that the FRP-to-FRP bond strength was affected even more by high temperature exposure with 90% loss in lap-splice near the glass transition temperature. An analy...

Abstract. The Mulliken-Boyce constitutive model predicts the dynamic response of crystalline polymers as a function of strain rate and temperature. This paper describes the Mulliken-Boyce model-based estimation of the constitutive parameters in a Bayesian probabilistic framework. Experimental data from dynamic mechanical analysis and dynamic compression of PVC samples over a wide range of strain rates are analyzed. Both experimental uncertainty and natural variations in the material properties are simultaneously considered as independent and joint distributions; the posterior probability distributions are shown and compared with prior estimates of the material constitutive parameters. Additionally, particular statistical distributions are shown to be effective at capturing the rate and temperature dependence of internal phase transitions in DMA data.

“…The degradation of the tensile strength of pultruded GFRP composites at elevated temperatures is much lower than that of the shear and compressive strengths because the former property is mainly governed by the fibres while the latter properties is dominated by the resin [5]. As a result, various empirical and mechanisms-based models that predict the temperature-dependent properties of composites have been developed, which are generally functions of either mass (or density) and/or temperature [7,[10][11][12][13][14]. Nevertheless, Correia et al [5] stated that additional experimental data are needed to validate previous results and that further research works are needed regarding the other important properties of pultruded composites profiles, particularly the shear modulus, the elastic modulus in the transverse direction and the interlaminar shear strength (ILSS), which is the limiting design characteristic for pultruded FRP [15].…”

A comparative study was conducted to evaluate the temperature-sensitive mechanical properties of glass fibre reinforced polymer (GFRP) composites in the longitudinal and transverse directions. GFRP coupons with different shear span-to-depth ratios were tested under three-point static bending test at temperatures ranging from room temperature up to 200 o C. Timoshenko Beam Theory-based procedure was then adopted to calculate the flexural and shear moduli of the GFRP laminates under moderate and elevated in-service temperatures.The results showed that the mechanical properties of the transversely cut specimens is affected more by the increase in temperature than the longitudinally cut specimens. Similarly, the interlaminar shear and flexural strengths of GFRP composites were found influenced more by elevated temperature compared to the stiffness properties. Moreover, the shear modulus undergone more severe degradation compared to the flexural modulus. Simplified empirical models were proposed to estimate the mechanical properties of the GFRP pultruded laminates in both the longitudinal and transverse directions at varying temperatures.
